description: Cell membranes are a key element of life because they keep the genetic material and metabolic machinery together. All present cell membranes are made of phospholipids, yet the nature of the first membranes and the origin of phospholipids are still under debate. We report here the first detection in space of ethanolamine, NH$_2$CH$_2$CH$_2$OH, which forms the hydrophilic head of the simplest and second most abundant phospholipid in membranes. The molecular column density of ethanolamine in interstellar space is $N$=(1.51$\pm$0.07)$\times$10$^{13}$ cm$^{-2}$, implying a molecular abundance with respect to H$_2$ of (0.9-1.4)$\times$10$^{-10}$. Previous studies reported its presence in meteoritic material but they suggested that it is synthesized in the meteorite itself by decomposition of amino acids. However, we find that the proportion of the molecule with respect to water in the interstellar medium is similar to the one found in the meteorite (10$^{-6}$). These results indicate that ethanolamine forms efficiently in space and, if delivered onto early Earth, it could have contributed to the assembling and early evolution of primitive membranes.

description: Software startups continue to be important drivers of economy globally. As the initial investment required to found a new software company becomes smaller and smaller resulting from technological advances such as cloud technology, increasing numbers of new software startups are born. Typically, the main argument for studying software startups is that they differ from mature software organizations in various ways, thus making the findings of many existing studies not directly applicable to them. How, exactly, software startups really differ from other types of software organizations as an on-going debate. In this paper, we seek to better understand how software startups differ from mature software organizations in terms of development practices. Past studies have primarily studied method use, and in comparison, we take on a more atomic approach by focusing on practices. Utilizing the Essence Theory of Software Engineering as a framework, we split these practices into categories for analysis while simultaneously evaluating the suitability of the theory for the context of software startups. Based on the results, we propose changes to the Essence Theory of Software Engineering for it to better fit the startup context.
Investigating the metabolic regulation of male fertility
Creators: name: Dimakopoulou, Anastasia
Publisher: name: Imperial College London
Year: 2019

description: Infertility is the inability to achieve pregnancy after 12 months of regular intercourse and is associated with male factors in 40% of couples. Currently, the diagnosis of male infertility is based on conventional semen analysis and management options involve assisted reproduction therapies for the female partner. The regulation of male fertility therefore remains under investigated. Recurrent pregnancy loss is the loss of 3 or more pregnancies before the 24th week of gestation. As half of the female partners have normal investigations, their male partners may be contributing to a significant extent, but male partners are not commonly investigated. By using a direct chemiluminescence assay to measure semen oxidative stress, my data showed markedly elevated oxidative stress in the semen of male partners affected by recurrent pregnancy loss. The main source of semen oxidative stress is leucocytes derived myeloperoxidase, a hyperactivated enzyme in chronic inflammatory states such as obesity. I have performed an in vivo study investigating the effect of a novel myeloperoxidase inhibitor on reproductive function in mice with diet-induced obesity. Having established that obesity has detrimental effects on male fertility from previously published studies, I investigated the effects of weight loss on obese male. Caloric restriction for weight loss was given to obese men over a period of two months and their semen parameters were compared to a control group who received simple observations over the same time period. In summary, I have identified a novel diagnostic marker for male partners of women with recurrent pregnancy loss. My weight loss study was the first randomised controlled study to identify the effects of caloric restriction in sperm function of obese men. These data have important implications for the diagnosis of male infertility and could provide an effective intervention for couples with male factor infertility associated with obesity.

description: This is a follow-up to our earlier work on the energies and radial distributions of heavy-light mesons. The heavy quark is taken to be static (infinitely heavy) and the light quark has a mass about that of the strange quark. We now concentrate on the energies of the excited states with higher angular momentum and with a radial node. A new improvement is the use of hypercubic blocking in the time direction. The calculation is carried out with dynamical fermions on a 16 cubed times 32 lattice with a lattice spacing approximately 0.1 fm generated using a non-perturbatively improved clover action. In nature the closest equivalent of this heavy-light system is the B_s meson, which allows us to compare our lattice calculations to experimental results (where available) or to give a prediction where the excited states, particularly P-wave states, should lie. We pay special attention to the spin-orbit splitting, to see which one of the states (for a given angular momentum L) has the lower energy. An attempt is made to understand these results in terms of the Dirac equation.

Nonideal evolution of nonaxisymmetric, force-free magnetic fields in a magnetar

Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: Recent numerical magnetohydrodynamic calculations by Braithwaite and collaborators support the `fossil field' hypothesis regarding the origin of magnetic fields in compact stars and suggest that the resistive evolution of the fossil field can explain the reorganisation and decay of magnetar magnetic fields. Here, these findings are modelled analytically by allowing the stellar magnetic field to relax through a quasistatic sequence of nonaxisymmetric, force-free states, by analogy with spheromak relaxation experiments, starting from a random field. Under the hypothesis that the force-free modes approach energy equipartition in the absence of resistivity, the output of the numerical calculations is semiquantitatively recovered: the field settles down to a linked poloidal-toroidal configuration, which inflates and becomes more toroidal as time passes. A qualitatively similar (but not identical) end state is reached if the magnetic field evolves by exchanging helicity between small and large scales according to an $α$-dynamo-like, mean-field mechanism, arising from the fluctuating electromotive force produced by the initial random field. The impossibility of matching a force-free internal field to a potential exterior field is discussed in the magnetar context.

Low-energy dipole excitations in $^{20}$O with antisymmetrized molecular dynamics

description: Low-energy dipole (LED) excitations in $^{20}$O were investigated by variation after $K$-projection of deformation($β$)-constraint antisymmetrized molecular dynamics combined with the generator coordinate method. We obtained two LED states, namely, the $1_1^-$ state with one-proton excitation on the relatively weak deformation and the $1_2^-$ state with a parity asymmetric structure of the normal deformation. The former is characterized by a toroidal dipole (TD) mode with vortical nuclear current, whereas the latter is associated with a low-energy $E1$ mode caused by surface neutron oscillation along the prolate deformation. The TD (vortical) and $E1$ modes separately appear as the $K^π=1^-$ and $K^π=0^-$ components of the deformed states, respectively, but couple with each other in the $1_1^-$ and $1_2^-$ states of $^{20}$O because of $K$-mixing, and shape fluctuation. As a result of the mixing, TD and $E1$ transition strengths are fragmented into the $1_1^-$ and $1_2^-$ states. We also obtained the $K^π=0^+$, $K^π=0^-$, and $K^π=1^-$ bands with cluster structures in the energy region higher than the LED states.

4-Dimensional Tissue Engineering via Cell Contractile Forces, Patterned RNA, and Kirigami
Creators: name: Gasvoda, Kaelyn
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Shape evolution within tissue development and healing is necessary for proper tissue function. However, emulating the in vivo curvature within an in vitro environment is difficult. Often in vitro environments are missing the dynamic component their in vivo counterparts have. Recently, there has been headway in implementing 4D engineering strategies by adding an actuator that produces a time-based shape morphing phenomena that occurs post construct fabrication in response to a stimulus. Here, the use of cell contractile forces (CCF) with and without RNAi, and kirigami methodologies in combination with cytocompatible hydrogels for tissue engineering applications was investigated. Both CCF and kirigami strategies coupled with time-based shape morphing have been reported previously; however, the complexity and intracity of these strategies have not been thoroughly explored. First, a bilayer system was investigated to demonstrate uniform shape morphing throughout a single construct, and to show multiaxial directional curvature while maintaining high cell viability. Moreover, this system supports chondrogenic differentiation of encapsulated cells while undergoing a shape transformation. Second, a single layer rapidly degradable hydrogel system was fabricated to produce simple shape morphing constructs that became cell-only condensations after a few days of culture. This system also demonstrated high cell viability of encapsulated cells and high differentiation capacity of encapsulated cells. Third, a single layer rapidly degradable hydrogel system patterned with RNAi to reduce the CCF locally and temporarily within a small region of the hydrogel constructs. Furthermore, this system demonstrated controllable directionality of axial curvature. Fourth, kirigami strategies were explored to fabricate a system that has multiple degrees of deformation within the same construct. Within this system, encapsulated cells exhibit a high cell viability while the hydrogel is undergoing shape deformations, and this system’s curvature produced can be sustained by matrix deposition brought on by chondrogenesis of encapsulated stem cells.

description: We investigate the effect of interspecies interaction on a degenerate mixture of bosonic 87Rb and fermionic 40K atoms in a three-dimensional optical lattice potential. Using a Feshbach resonance, the 87Rb-40K interaction is tuned over a wide range. Through an analysis of the 87Rb momentum distribution, we find a pronounced asymmetry between strong repulsion and strong attraction. In the latter case, the Bose-Hubbard parameters are renormalized due to self-trapping, leading to a marked shift in the superfluid to Mott insulator transition with increasing Bose-Fermi interaction.

description: The H2020 METRO-HAUL European project has architected a latency-aware, cost-effective, agile, and programmable optical metro network. This includes the design of semidisaggregated metro nodes with compute and storage capabilities, which interface effectively with both 5G access and multi-Tbit/s elastic optical networks in the core. In this paper, we report the automated deployment of 5G services, in particular, a public safety video surveillance use case employing low-latency object detection and tracking using on-camera and on-the-edge analytics. The demonstration features flexible deployment of network slice instances, implemented in terms of European Telecommunications Standards Institute (ETSI) network function virtualization network services. We summarize the key findings in a detailed analysis of end-to-end quality of service, service setup time, and soft-failure detection time. The results show that the round-trip time over an 80 km link is under 800s and the service deployment time is under 180s.

description: This paper investigates the impact of coronavirus disease 2019 (COVID-19) on the Chinese stock market. We show that the COVID-19 outbreak not only hurts the stock returns but also affects the stock price sensitivity to firm-specific information. We document heterogeneous effects of the epidemic infection scale and the public attention about the pandemic. The stock market response to firm-specific information is decelerated (accelerated) by the public attention (infection scale). Moreover, the decreasing (increasing) effect of the public attention (infection scale) on such response is more intensive to positively toned (negatively toned) firm-specific news articles. Finally, we observe price reversal (momentum) following the public attention (infection scale).

description: With the fast development of biological techniques, high-throughput omics data is available, which also raises many big problems in other subjects like mathematics: how to deal with such big data so that meaningful biological insights can be found. Among the various omics data, I mainly work on Matrix-Assisted Laser Desorption Ionization Mass Spectrometry and Single Cell RNA Sequencing data. Although there already exist many mature analysis pipelines and machine learning algorithms for analysing these kinds of omics data, there remains improvement space. In this thesis, I firstly describe the relevant challenges of omics data analysis in detail. Then I explain popular analysis pipelines and algorithms which are frequently utilized during the analysis. Finally, I illustrate the modified analysis pipeline, math models and corresponding results.

description: A strong emission line at 6703A has been detected in the optical spectrum for the host galaxy (R=23.1) of the radio source RC J0311+0507 (4C+04.11). This radio galaxy, with a spectral index of 1.31 in the frequency range 365-4850 MHz, is one of the ultrasteep spectrum objects from the deep survey of a sky strip conducted with RATAN-600 in 1980-1981. We present arguments in favor of the identification of this line with Lyαat redshift z=4.514. In this case, the object belongs to the group of extremely distant radio galaxies of ultrahigh radio luminosity (P_{1400}=1.3 x 10^{29}W Hz^{-1}). Such power can be provided only by a fairly massive black hole (~10^9M_\sun}) that formed in a time less than the age of the Universe at the observed z(1.3 Gyr) or had a primordial origin.

Diagnosis of psychopathy in a forensic psychiatric population
Creators: name: Hart, Stephen David
Publisher: name: University of British Columbia
Year: 2010

description: Both researchers and clinicians, especially those working in criminal populations, have long suggested that psychopathy (or antisocial personality disorder) and schizophrenia are associated on an etiological or on some other level (e.g., Eysenck and Eysenck, 1976, 1978). Others (Hare, 1984; Hare and Harpur, 1986; Raine, 1985) argue that psychopathy is not associated (or even negatively associated) with other psychiatric disorders, including schizophrenia. To evaluate these competing positions concerning the psychopathy-schizophrenia association, 80 male prisoners remanded to a forensic psychiatric institute for assessment of their fitness to stand trial were diagnosed using both the Psychopathy Checklist (PCL; Hare, 1980, 1985a) and DSM-III Axis I and II criteria. In addition, clinical global ratings and self-report inventories were used to measure the strength of psychopathy- and schizophrenia-related traits. The results indicated that: a) although diagnoses of psychopathy (according to PCL criteria) did not have perfect specificity with respect to schizophrenia-related clinical diagnoses, the overlap was small, and the PCL scales were either not associated or negatively associated with these disorders; b) diagnoses of antisocial personality disorder (APD, according to DSM-III criteria) were generally not associated with schizophrenia-related disorders, but had lower clinical specificity than did the PCL criteria with respect to both schizophrenia-related and other psychiatric disorders; c) there was no association between psychopathy- and schizophrenia-related clinical ratings; d) psychopathy and APD diagnoses and clinical ratings were not related to scores on other standard rating scales of the severity of psychiatric symptomatology; and e) there was no difference between schizophrenic and non-schizophrenic subjects in the strength of psychopathy-related traits, and no difference between psychopaths and nonpsychopaths (or APD versus non-APD subjects) in the strength of schizophrenia-related traits. As well, self-report measures related to psychopathy and schizophrenia did not correlate with each other, or with clinical ratings of the two disorders. The results are interpreted as supporting the view that psychopathy is not positively associated with schizophrenia or with psychiatric disorder in general. The practical utility of various techniques for assessing psychopathy in forensic psychiatric populations is also discussed.

description: I discuss the relation between inclusive and exclusive dynamics suggested by Bloom-Gilman duality. Duality implies the simultaneous applicability of two distinct limits, the standard DIS limit of hard inclusive processes taken at fixed xB and a limit where the hadronic mass is held fixed. I review experimental evidence for the relevance of the fixed mass limit in inclusive processes at high xF. Semi-local duality suggests that inclusive and exclusive processes occur on the same target Fock states. DIS scaling then implies that the Fock states contributing to hard exclusive processes have a large transverse size, i.e., that the hard scattering occurs off a single parton which carries a large fraction of the hadron momentum.

description: One of the requirements of the population-based approach to Structural Health Monitoring (SHM) proposed in the earlier papers in this sequence, is that structures be represented by points in an abstract space. Furthermore, these spaces should be metric spaces in a loose sense; i.e. there should be some measure of distance applicable to pairs of points; similar structures should then be close in the metric. However, this geometrical construction is not enough for the framing of problems in data-based SHM, as it leaves undefined the notion of feature spaces. Interpreting the feature values on a structure-by-structure basis as a type of field over the space of structures, it seems sensible to borrow an idea from modern theoretical physics, and define feature assignments as sections in a vector bundle over the structure space. With this idea in place, one can interpret the effect of environmental and operational variations as gauge degrees of freedom, as in modern gauge field theories. This paper will discuss the various geometrical structures required for an abstract theory of feature spaces in SHM, and will draw analogies with how these structures have shown their power in modern physics. In the second part of the paper, the problem of determining the normal condition cross section of a feature bundle is addressed. The solution is provided by the application of Graph Neural Networks (GNN), a versatile non-Euclidean machine learning algorithm which is not restricted to inputs and outputs from vector spaces. In particular, the algorithm is well suited to operating directly on the sort of graph structures which are an important part of the proposed framework for PBSHM. The solution of the normal section problem is demonstrated for a heterogeneous population of truss structures for which the feature of interest is the first natural frequency.

description: We present measurements of the fluorine abundance in a Galactic Bulge Asymptotic Giant Branch (AGB) star. The measurements were performed using high resolution K-band spectra obtained with the CRIRES spectrograph, which has been recently installed at ESO's VLT, together with state-of-the-art model atmospheres and synthetic spectra. This represents the first fluorine abundance measurement in a Galactic Bulge star, and one of few measurements of this kind in a third dredge-up oxygen-rich AGB star. The F abundance is found to be close to the solar value scaled down to the metallicity of the star, and in agreement with Disk giants that are comparable to the Bulge giant studied here. The measurement is of astrophysical interest also because the star's mass can be estimated rather accurately ($1.4 \lesssim M/\mathrm{M}_{\sun} \lesssim 2.0$). AGB nucleosynthesis models predict only a very mild enrichment of F in such low mass AGB stars. Thus, we suggest that the fluorine abundance found in the studied star is representative for the star's natal cloud, and that fluorine must have been produced at a similar level in the Bulge and in the Disk.

An examination of the benefits and implementation problems of the transportation/utility corridor concept
Creators: name: Klassen, June Peterson
Publisher: name: University of British Columbia
Year: 2010

description: The value and feasibility of implementing the Corridor concept has been debated for over twenty years. A corridor provides land for the coordinated placement of future linear facilities such as highways, railways, pipelines, powerlines and municipal services. Few corridors have been established, although there has been obvious interest in the concept. A number of studies into the feasibility of establishing corridors have been completed in the United States, Alberta and British Columbia. This thesis examines the benefits, disadvantages and implementation problems associated with the corridor concept. Through a literature review, the factors influencing linear facility right-of-way location and width are examined. Also, from the literature, the benefits and disadvantages associated with corridor implementation and the key factors which have inhibited corridor implementation are identified. The Alberta corridor program is studied and the corridor origins, design, institutional framework and implementation mechanism identified. The case study indicated that a set of unusual circumstances allowed for the establishment of the Alberta corridors. This thesis concludes that corridors do provide net benefits for the community in the long term but that they are difficult to implement. The major planning implication of corridors is that they bring right-of-way planning into the sphere of land use planning and reduce the emphasis on economics and engineering.
Quantum enhancement of N-photon phase sensitivity by interferometric addition of down-converted photon pairs to weak coherent light

description: It is shown that the addition of down-converted photon pairs to coherent laser light enhances the N-photon phase sensitivity due to the quantum interference between components of the same total photon number. Since most of the photons originate from the coherent laser light, this method of obtaining non-classical N-photon states is much more efficient than methods based entirely on parametrically down-converted photons. Specifically, it is possible to achieve an optimal phase sensitivity of about delta phi^2=1/N^(3/2), equal to the geometric mean of the standard quantum limit and the Heisenberg limit, when the average number of down-converted photons contributing to the N-photon state approaches (N/2)^(1/2).
description: 21 pages, including 6 figures. Extended version gives more details on down-conversion efficiencies and clarifies the relation between phase sensitivity and squeezing. The title has been changed in order to avoid misunderstandings regarding these concepts

description: We report the discovery of a new high mass X-ray binary pulsar, XMMU J050722.1-684758, possibly associated with the supernova remnant MCSNR J0507-6847 in the Large Magellanic Cloud, using XMM-Newton X-ray observations. Pulsations with a periodicity of 570 s are discovered from the Be X-ray binary XMMU J050722.1-684758 confirming its nature as a HMXB pulsar. The HMXB is located near the geometric centre of the supernova remnant MCSNR J0507-6847 (0.9 arcmin from the centre) which supports the XRB-SNR association. The estimated age of the supernova remnant is 43-63 kyr which points to a middle aged to old supernova remnant. The large diameter of the supernova remnant combined with the lack of distinctive shell counterparts in optical and radio indicates that the SNR is expanding into the tenous environment of the superbubble N103. The estimated magnetic field strength of the neutron star is $B\gtrsim10^{14}$ G assuming a spin equilibrium condition which is expected from the estimated age of the parent remnant and assuming that the measured mass-accretion rate remained constant throughout.

Identifying Bee Diseases in the Apiary

Subjects: Livestock Production/Industries

description: Excerpts from the report: Bee diseases are found throughout the United States wherever bees are kept. These diseases cause large annual losses in bees, honey, and equipment and materially add to the cost of honey production. Even greater financial losses can result when the field force of pollinating bees is reduced, with consequent lower yield of seed and fruit. Because of the bee's manner of living, any contagious disorder will spread within the colony. The crowding of colonies together in apiaries increases the possibility of the spread of diseases to other colonies by robbing or drifting bees, and the use of movable frames is apt to spread diseases from hive to hive.

description: Human mobility is crucial to understand the transmission pattern of COVID-19 on spatially embedded geographic networks. This pattern seems unpredictable, and the propagation appears unstoppable, resulting in over 350,000 death tolls in the U.S. by the end of 2020. Here, we create the spatiotemporal inter-county mobility network using 10 TB (Terabytes) trajectory data of 30 million smart devices in the U.S. in the first six months of 2020. We investigate its bound percolation by removing the weakly connected edges. The mobility network becomes vulnerable and prone to reach its criticality and thus experience surprisingly abrupt phase transitions. Despite the complex behaviors of the mobility network, we devised a novel approach to identify a small, manageable set of recurrent critical bridges, connecting the giant component and the second-largest component. These adaptive links, located across the United States, played a key role as valves connecting components in divisions and regions during the pandemic. Beyond, our numerical results unveil that network characteristics determine the critical thresholds and the bridge locations. The findings provide new insights into managing and controlling the connectivity of mobility networks during unprecedented disruptions. The work can also potentially offer practical future infectious diseases both globally and locally.

description: Over the last few years instruments such as VLT/SPHERE and Subaru/HiCIAO have been able to take detailed scattered light images of protoplanetary discs. Many of the features observed in these discs are generally suspected to be caused by an embedded planet, and understanding the cause of these features requires detailed theoretical models. In this work we investigate disc-planet interactions using the PLUTO code to run 2D and 3D hydrodynamic simulations of protoplanetary discs with embedded 30 M$_{\oplus}$ and 300 M$_{\oplus}$ planets on both an inclined ($i = 2.86^{\circ}$) and non-inclined orbit, using an $α$-viscosity of $4 \times 10^{-3}$. We produce synthetic scattered-light images of these discs at \emph{H-band} wavelengths using the radiative transfer code RADMC3D. We find that while the surface density evolution in 2D and 3D simulations of inclined and non-inclined planets remain fairly similar, their observational appearance is remarkably different. Most of the features seen in the synthetic \emph{H-band} images are connected to density variations of the disc at around 3.3 scale heights above and below the midplane, which emphasizes the need for 3D simulations. Planets on sustained orbital inclinations disrupt the disc's upper-atmosphere and produce radically different observable features and intensity profiles, including shadowing effects and intensity variation in the order of 10-20 times the surrounding background. The vertical optical depth to the disc midplane for \emph{H-band} wavelengths is $τ\approx 20$ in the disc gap created by the high-mass planet. We conclude that direct imaging of planets embedded in the disc remains difficult to observe, even for massive planets in the gap.
Partially coherent matter wave and its evolution

description: The evolution and propagation of a partially coherent matter wave (PCMW) is investigated theoretically by the correlation function method. The ABCD matrix formalism previously used for a fully coherent matter wave is extended to the PCMW domain. A new ABCD law is derived, using a tensor method to describe the evolution of a PCMW. An analytical solution of the first-order correlation function is obtained that makes the propagation and evolution of a PCMW very simple and clear. As an example, the propagation of a PCMW in a gravitational field is calculated numerically.

Is a soft nuclear equation of state extracted from heavy-ion data incompatible with pulsar data?

description: We discuss the recent constraints on the nuclear equation of state from pulsar mass measurements and from subthreshold production of kaons in heavy-ion collisions. While recent pulsar data points towards a hard equation of state, the analysis of the heavy-ion data allows only for soft equations of state. We resolve the apparent contradiction by considering the different density regimes probed. We argue that future measurements of global properties of low-mass pulsars can serve as an excellent cross-check to heavy-ion data.

On the Vertical Shear Instability in Magnetized Protoplanetary Disks

description: The vertical shear instability (VSI) is a robust phenomenon in irradiated protoplanetary disks (PPDs). While there is extensive literature on the VSI in the hydrodynamic limit, PPDs are expected to be magnetized and their extremely low ionization fractions imply that non-ideal magneto-hydrodynamic (MHD) effects should be properly considered. To this end, we present linear analyses of the VSI in magnetized disks with Ohmic resistivity. We primarily consider toroidal magnetic fields, which are likely to dominate the field geometry in PPDs. We perform vertically global and radially local analyses to capture characteristic VSI modes with extended vertical structures. To focus on the effect of magnetism, we use a locally isothermal equation of state. We find that magnetism provides a stabilizing effect to dampen the VSI, with surface modes, rather than body modes, being the first to vanish with increasing magnetization. Subdued VSI modes can be revived by Ohmic resistivity, where sufficient magnetic diffusion overcome magnetic stabilization, and hydrodynamic results are recovered. We also briefly consider poloidal fields to account for the magnetorotational instability (MRI), which may develop towards surface layers in the outer parts of PPDs. The MRI grows efficiently at small radial wavenumbers, in contrast to the VSI. When resistivity is considered, we find the VSI dominates over the MRI for Ohmic Elsässer numbers $\lesssim 0.09$ at plasma beta parameter $β_Z \sim 10^4$.

Constraints on large scale inhomogeneities from WMAP-5 and SDSS: confrontation with recent observations

description: Measurements of the SNe Ia Hubble diagram which suggest that the universe is accelerating due to the effect of dark energy may be biased because we are located in a 200-300 Mpc underdense "void" which is expanding 20-30% faster than the average rate. With the smaller global Hubble parameter, the WMAP-5 data on cosmic microwave background anisotropies can be fitted without requiring dark energy if there is some excess power in the spectrum of primordial perturbations on 100 Mpc scales. The SDSS data on galaxy clustering can also be fitted if there is a small component of hot dark matter in the form of 0.5 eV mass neutrinos. We show however that if the primordial fluctuations are gaussian, the expected variance of the Hubble parameter and the matter density are far too small to allow such a large local void. Nevertheless many such large voids have been identified in the SDSS LRG survey in a search for the late-ISW effect due to dark energy. The observed CMB temperature decrements imply that they are nearly empty, thus these real voids too are in gross conflict with the concordance LCDM model. The recently observed high peculiar velocity flow presents another challenge for the model. Therefore whether a large local void actually exists must be tested through observations and cannot be dismissed a priori.
