A search for FRB 121102-like persistent radio-luminous sources -- Candidates and implications for the FRB rate and searches

description: The localization of the repeating fast radio burst (FRB), FRB 121102, suggests that it is associated with a persistent radio-luminous compact source in the FRB host galaxy. Using the FIRST radio catalog, I present a search for luminous persistent sources in nearby galaxies, with radio luminosities >10% of the FRB 121102 persistent source luminosity. The galaxy sample contains about 30% of the total galaxy g-band luminosity within <108 Mpc, in a footprint of 10,600 deg^2. After rejecting sources likely due to active galactic nuclei activity or background sources, I remain with 11 candidates that are presumably associated with galactic disks or star formation regions. At least some of these candidates are likely to be due to chance alignment. In addition, I find 85 sources within 1" of galactic nuclei. Assuming the radio persistent sources are not related to galactic nuclei and that they follow the galaxy g-band light, the 11 sources imply a 95% confidence upper limit on the space density of luminous persistent sources of <5x10^-5 Mpc^-3, and that at any given time only a small fraction of galaxies host a radio luminous persistent source (<10^-3 L_*^-1). Assuming persistent sources life time of 100 yr, this implies a birth rate of <5x10^-7 yr^-1 Mpc^-3. Given the FRB volumetric rate, and assuming that all FRBs repeat and are associated with persistent radio sources, this sets a lower limit on the rate of FRB events per persistent source of >0.8 yr^-1. I argue that these 11 candidates are good targets for FRB searches and I estimate the FRB event rate from these candidates.

description: An overview of space tests searching for small deviations from special relativity arising at the Planck scale is given. Potential high-sensitivity space-based experiments include ones with atomic clocks, masers, and electromagnetic cavities. We show that a significant portion of the coefficient space in the Standard-Model Extension, a framework that covers the full spectrum of possible effects, can be accessed using space tests. Some remarks on Lorentz violation in the gravitational sector are also given.

description: We examine the properties of two galaxy "halos" at z ~ 0.7 in the TON 153 (z_em = 1.01) quasar field. The first absorber-galaxy pair (G1) is a z = 0.672, L_B = 4.3 L*_B, E/S0 galaxy probed at D = 58 kpc. G1 is associated with a remarkable five-component Ly-alpha complex having tau_LL < 0.4, W_r(Lya) = 2.8 A, and a velocity spread of v = 1420 km/s. We find no MgII, CIV, NV, nor OVI absorption in these clouds and infer metallicity upper limits of -3 < log(Z/Z_sun) < -1, depending upon assumptions of photoionized or collisionally ionized gas. The second absorber-galaxy pair (G2) is a z = 0.661, L_B = 1.8 L*_B, Sab galaxy probed at D = 103 kpc. G2 is associated with metal--enriched (log Z/Z_sun ~ -0.4) photoionized gas having N(HI) ~ 18.3 and a velocity spread of v = 200 km/s. The very different G1 and G2 systems both have gas-galaxy properties inconsistent with the standard luminosity dependent galaxy "halo" model commonly invoked for quasar absorption line surveys. We emphasize that mounting evidence is revealing that extended galactic gaseous envelopes in the regime of D < 100 kpc do not exhibit a level of homogeneity supporting a standardized halo model. Selection effects may have played a central role in the development of a simple model. We discuss the G1 and G2 systems in the context of Lambda-CDM models of galaxy formation and suggest that the heterogeneous properties of absorber-galaxy pairs is likely related to the range of overdensities from which galaxies and gas structures arise.

description: We evaluate the model-dependent piece of O(alpha) long-distance radiative corrections to tau^- \to π^- π^0ν_τ decays by using a meson dominance model. We find that these corrections to the di-pion invariant mass spectrum are smaller than in previous calculations based on chiral perturbation theory. The corresponding correction to the photon inclusive rate is tiny (-0.15%) but it can be of relevance when new measurements reach better precision.

description: One of the main challenges of securing broadcast communication is source authentication, or enabling receivers of broadcast data to verify that the received data really originates from the claimed source and was not modified en route. This problem is complicated by mutually untrusted receivers and unreliable communication environments where the sender does not retransmit lost packets. This article presents the TESLA (Timed Efficient Stream Loss-tolerant Authentication) broadcast authentication protocol, an efficient protocol with low communication and computation overhead, which scales to large numbers of receivers, and tolerates packet loss. TESLA is based on loose time synchronization between the sender and the receivers. Despite using purely symmetric cryptographic functions (MAC functions), TESLA achieves asymmetric properties. We discuss a PKI application based purely on TESLA, assuming that all network nodes are loosely time synchronize

description: Herbert Meyer was born in Cologne in 1911 of Jewish heritage. His PhD studies in organic chemistry were disrupted in the late 1930s, but he managed to get his PhD in only two years at the University of Cologne and escaped to England in 1939. He applied to be a pilot in the RAF but was rejected as still a German national. He managed to gain employment at Phillip Mineral and Chemical corporation at Brimsdown, Enfield where he was in charge of research on phosphorescent chemicals (phosphors) used to coat cathode ray screens which light up to produce the pictures on TV, oscilloscope or radar screens. He developed a machine for automated testing of large numbers of novel materials to improve the performance of the screens. He rarely ever spoke about his wartime experiences, but as an old man he once proudly mentioned his unlikely role in the Battle of Britain.He said that although he had failed to become a pilot, during the war, he was the only civilian in Britain to hold a pass in to any military base in the country! This was because he was supplying screens for radar with improved phosphors which glowed for longer. This allowed operators of radar to follow the flight of enemy bombers continuously as lines rather than as a series of flashes which faded until the next flash appeared.I did not pay much attention at the time although the unique permit did seem very strange. It was clarified years later (after his death) when I saw a TV programme on the Battle of Britain which explained that radar information on enemy bombers heading to bomb airfields with fighter planes on the ground was sent to a central control room at Uxbridge RAF, from which a message to 'Scramble' was issued just in time to get the fighters airborne and so preserve ther fighter squadrons until they were able to carry the fight to the enemy. It seems likely that the quality of the radar data was critical to carry out these rapid escapes of pilots and planes, which in the long run led to victory in the Battle of Britain. Only then did I realise the potential importance of my father's work and his unique military pass.From the information I have, I do not know if his work and his pass was valid during the Battle of Britain or only later during the war. Presumably the MOD may retain information on when the pass was issued, but it may have been/still be an official secret.
Hardness-Intensity Correlations in Magnetar Afterglows

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We explore the hardness-intensity correlations observed in several AXPs and SGRs within the framework of a thermally emitting magnetar model. Using our detailed atmosphere models and taking into account reprocessing of the surface emission by the magnetosphere, we show that the hardness of the surface spectra increases with increasing temperature and hence the changes in the effective temperatures of the outer layers of the star alone can account for the observed correlations. We conclude that the slow release of the heat deposited in the deep crust during a magnetar burst naturally accounts for the spectral changes during the afterglow. The correlations are further enhanced by changes in the structures of the magnetic currents during or following a burst. However, the additional hardening produced by scattering of the surface photons off the magnetospheric charges saturates at moderate values of the scattering optical depth.

description: Comets are icy objects that orbitally evolve from the trans-Neptunian region (the Kuiper belt and beyond) into the inner Solar System, where they are heated by solar radiation and become active due to sublimation of water ice. Here we perform end-to-end simulations in which cometary reservoirs are formed in the early Solar System and evolved over 4.5 Gyr. The gravitational effects of Planet 9 (P9), hypothesized to circle the Sun on a wide orbit, are included in some of our simulations. Different models are considered for comets to be active, including a simple assumption that comets remain active for Np(q) perihelion passages with perihelion distance q<2.5 au. The orbital distribution and number of active comets produced in our model is compared to observations. The orbital distribution of ecliptic comets (ECs) is well reproduced in models with Np(2.5)=500 and without P9. With P9, the inclination distribution of model ECs is wider than the observed one. We find that the known Halley-type comets (HTCs) have a nearly isotropic inclination distribution (with only a slight preference for prograde orbits). In our model, the HTCs appear to be an extension of the population of returning Oort-cloud comets (OCCs) to shorter orbital periods. The inclination distribution of model HTCs becomes broader with increasing Np, but the existing observational data are not good enough to constrain Np from orbital fits. Np(2.5)>1000 is required to obtain a steady-state population of large active HTCs that is consistent with observations. To fit the ratio of the returning-to-new OCCs, by contrast, our model implies that Np(2.5)<10, possibly because the detected long-period comets are smaller and much easier to disrupt than observed HTCs.

Experimental values of $S_{η' K}$ are now seen to be closer to the Standard Model expectations, fully consistent with the new improved bounds.

Identification of Z Cam's Historical Counterpart: The Quest for an Ancient Nova

description: In recent astronomical discussions, attempts have been made to link the known dwarf nova Z Cam to historical celestial events, particularly the "guest star" phenomenon reported in China in 77 BCE. Despite other suggestions and the problems with regard to the location of the event in 77 BCE, its identification with Z Cam is used in the Variable Star IndeX (VSX) of the AAVSO and in several research papers that aim to derive knowledge on the evolution of cataclysmic variables. Through the reconstruction of the super-constellation of the Purple Palace in the Han Dynasty, we found that Z Cam is actually located outside this enclosure, contradicting the records of the 77 BCE guest star being "within the Purple Palace". With newly found text versions of the guest star in 77 BCE, we narrowed down the position given therein. Combined with a new analysis of accompanying divination text leads to the conclusion that this guest star was actually a comet. Finally, through meticulous examination and comparison, we conclude that the guest star of 369 CE appears the most plausible candidate for Z Cam's historical counterpart, aligning with both textual evidence and modern astronomical observations.

title: The Influence of Culture on the Performance of Mergers & Acquisitions

Publisher: name: TU Wien
Year: 2023
Subjects: subject: Mergers and Acquisitions
subject: Cultural Influence

description: This thesis paper explores the relationship between culture and the performance of mergers and acquisitions (M&As) and provides valuable new insights into this complex interplay. The analysis conducted during this research concludes that culture significantly affects the outcomes of M&As, with impacts ranging from positive to negative or, in some selective studies, to neutral. Interestingly, the study method employed during the research could not determine a direct relationship between research methodologies and cultural impacts, suggesting that the diverse findings can be attributed to more than just different research approaches. However, the analysis also reveals that the existing academic research on M&As encompasses a wide range of culture constructs, contributing to a lack of consensus and adding to the uncertainty surrounding the impact of culture. This diversity provescounterproductive, making it challenging to draw definitive conclusions.

description: High spatial and temporal resolution images of a sunspot, obtained simultaneously in multiple optical and UV wavelengths, are employed to study the propagation and damping characteristics of slow magnetoacoustic waves up to transition region heights. Power spectra are generated from intensity oscillations in sunspot umbra, across multiple atmospheric heights, for frequencies up to a few hundred mHz. It is observed that the power spectra display a power-law dependence over the entire frequency range, with a significant enhancement around 5.5 mHz found for the chromospheric channels. The phase-difference spectra reveal a cutoff frequency near 3 mHz, up to which the oscillations are evanescent, while those with higher frequencies propagate upwards. The power-law index appears to increase with atmospheric height. Also, shorter damping lengths are observed for oscillations with higher frequencies suggesting frequency-dependent damping. Using the relative amplitudes of the 5.5 mHz (3 minute) oscillations, we estimate the energy flux at different heights, which seems to decay gradually from the photosphere, in agreement with recent numerical simulations. Furthermore, a comparison of power spectra across the umbral radius highlights an enhancement of high-frequency waves near the umbral center, which does not seem to be related to magnetic field inclination angle effects.

description: Markarian 421 (Mrk 421) was the first blazar detected at gamma-ray energies above 300 GeV, and it remains one of only twelve TeV blazars detected to date. TeV gamma-ray measurements of its flaring activity and spectral variability have placed constraints on models of the high-energy emission from blazars. However, observations between 50 and 300 GeV are rare, and the high-energy peak of the spectral energy distribution (SED), predicted to be in this range, has never been directly detected. We present a detection of Mrk 421 above 100 GeV as made by the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) during a multiwavelength campaign in early 2004. STACEE is a ground-based atmospheric Cherenkov telescope using the wavefront sampling technique to detect gamma rays at lower energies than achieved by most imaging Cherenkov telescopes. We also outline a method for reconstructing gamma-ray energies using a solar heliostat telescope. This technique was applied to the 2004 data, and we present the differential energy spectrum of Mrk 421 above 130 GeV. Assuming a differential photon flux dN/dE proportional to E^-a, we measure a spectral index a = 2.1 +/- 0.2 (statistical) +0.2/-0.1 (systematic). Finally, we discuss the STACEE spectrum in the context of the multiwavelength results from the same epoch.

description: Thousands of papers and comments have been written about what Open Internet policies would best serve the public interest, and thousands more have been written about whether better Open Internet policies could be supported by calling Internet access a telecommunications service under Title II of the Communications Act or an information service. Even the authors of this comment have written about these topics.123 However, this particular comment will address neither of these topics. Instead, it will consider only whether or not commercial Internet access is or is not a telecommunications service under current law. Although many issues are delegated to the FCC as an expert agency, the FCC is still required to follow the laws passed by Congress and signed by the President, and the FCC’s discretion has bounds. In this matter, we find that the Communications Act of 1934 as modified by the Telecommunications Act requires the FCC to define commercial Internet access as a telecommunications service. Opinions will differ as to whether this is a good or bad result for the future of the Internet, but this question is outside the scope of this comment.

description: The debate over “network neutrality” has recently emerged as the single most important communications policy issue—at least within the United States—that is now being debated around the world. The resolution of this debate may greatly influence what applications and content are available to Internet users, which business models are successful for service providers, which modes of social communication develop, and which technical designs are effective. As applications move to become Internet Protocol (IP)-based, the reverberations will also reach those sectors that build on or compete with the Internet, including the telephone, television, radio, and electronic commerce sectors. The magnitude of this issue demands careful consideration by policymakers. The papers in this special issue can serve as a valuable basis for such consideration.

description: Rising concentrations of greenhouse gases (GHGs) in the atmosphere have already caused perceptible changes in climate and will lead to further climate change in the future (Intergovernmental Panel on Climate Change 2001). The impact of climate change in California may be particularly significant in some areas: water resources, agriculture, and sensitive coastal and forest ecosystems (Shaw 2002; Roos 2003; Hayhoe, Cayan et al. 2004). In turn, these impacts could have serious repercussions for the economy and public health of the State, and for California’s agricultural and recreation industries.

description: We consider a family of multivariate trace inequalities recently derived by Sutter, Berta and Tomamichel. These inequalities generalize the Golden-Thompson inequality and Lieb's three-matrix inequality to an arbitrary number of matrices in a way that features complex matrix powers. We show that their inequalities can be rewritten as an $n$-matrix generalization of Lieb's original three-matrix inequality. The complex matrix powers are replaced by resolvents and appropriate maximally entangled states. We expect that the technically advantageous properties of resolvents, in particular for perturbation theory, can be of use in applications of the $n$-matrix inequalities, e.g., for analyzing the rotated Petz recovery map in quantum information theory.

Subjects: Infrastucture, Open Access, Europe

description: Recently launched, OpenAIRE2020 is the European Union initiative for an Open Access Infrastructure for Research which supports open scholarly communication and access to the research output of European-funded projects. The substantial technical infrastructure operates on two levels: Gathering research outputs: OpenAIRE gathers open access content from a network of institutional and disciplinary repositories. To put this into practice, an integrated suite of guidelines has been developed so that data sources, namely literature and data repositories, OA publishers and CRIS systems can be harvested and their contents made more visible. The portal gives access to EU-funded scientific publications, and also provides monitoring tools for depositing and usage statistics. Policy harmonisation and community outreach: OpenAIRE has a collaborative and thriving ‘human’ network, which is pan-European in nature. The community works to advance open access initiatives at national levels. It has National Open Access Desks in nearly 30 countries, and operates a European Helpdesk system for all matters concerning open access, copyright and repository interoperability. OpenAIRE is starting to move from a publication infrastructure to a more comprehensive infrastructure that covers all types of scientific output, and is establishing an infrastructure to harvest, enrich and store the metadata of scientific datasets. Cross-links from publications to data and funding schemes will be supported. This interlinking of research objects has implications for optimising the research process, allowing the sharing, enrichment and reuse of data. The poster presented will outline the activities of OpenAIRE. It will also highlight the following themes: advocating open access, repository guidelines, visibility of the European research environment, enhanced publications and sharing and reuse of research data.

description: We present first results of XMM-Newton X-ray observations of the infrared cluster lying near the NGC 2071 reflection nebula in the Orion B region. This cluster is of interest because it is one of the closest regions known to harbor embedded high-mass stars. We report the discovery of hard X-ray emission from the dense central NGC 2071-IR subgroup which contains at least three high-mass young stellar objects (NGC 2071 IRS-1, IRS-2, and IRS-3). A prominent X-ray source is detected within 1 arcsecond of the infrared source IRS-1, which is thought to drive a powerful bipolar molecular outflow. The X-ray spectrum of this source is quite unusual compared to the optically thin plasma spectra normally observed in young stellar objects (YSOs). The spectrum is characterized by a hard broad-band continuum plus an exceptionally broad emission line at approximately 6.4 keV from neutral or near-neutral iron. The fluorescent Fe line likely originates in cold material near the embedded star (i.e. a disk or envelope) that is irradiated by the hard heavily-absorbed X-ray source.

description: The origins of the extraterrestrial neutrinos observed in IceCube have yet to be determined. In this study we perform a one-point fluctuation analysis of the six-year high-energy starting event (HESE) shower data, with fixed non-Poissonian contributions from atmospheric, Galactic and some extragalactic components, as well as an isotropic (and weakly non-Poissonian) template. In addition to the star-forming galaxies and blazars, our analysis suggests the presence of an additional isotropic component, not associated with any known class of sources, with best-fit intensity of $(2.8\pm0.2)\times 10^{-18}\,(E/100~{\rm TeV})^{-2.7\pm 0.5}$ ${\mathrm{cm}^{-2}\, \mathrm{s}^{-1}\,\mathrm{sr}^{-1}\,\mathrm{GeV}^{-1}}$. For the first time, we also consider high-energy extrapolations of several phenomenological models for the diffuse Galactic emission (tuned to both local cosmic-ray data and diffuse gamma-ray emission in the GeV-TeV domain). We demonstrate the potential of our framework in discriminating between different scenarios, with possible implications on the physics of cosmic ray transport in the TeV-PeV range.

Radiative $B\to K_1$ decays in the light-cone sum rules

description: The weak form factor for $B\to K_{1B}$ where $K_{1B}$ is the $^1P_1$ state is calculated in the light-cone sum rules (LCSR). Combining the quark model result for the form factor of $B\to K_{1A}$ with $K_{1A}$ being the $^3P_1$ state, we have larger values for $B\to K_1$ form factors than the previous LCSR results. The increased form factors reduce the discrepancy between theory and the experimental data for $B\to K_1 γ$. Some phenomenological meanings are also discussed.

description: This article presents a theoretical analysis of a one-dimensional heat transfer problem in two layers involving diffusion, advection, internal heat generation or loss linearly dependent on temperature in each layer, and heat generation due to external sources. Additionally, the thermal resistance at the interface between the materials is considered. The situation of interest is modeled mathematically, explicit analytical solutions are found using Fourier techniques, and a convergent finite difference scheme is formulated to simulate specific cases. The solution is consistent with previous results. A numerical example is included that shows coherence between the obtained results and the physics of the problem. The conclusions drawn in this work expand the theoretical understanding of two-layer heat transfer and may also contribute to improving the thermal design of multilayer engineering systems.

description: This paper takes a known approach for scheduling and admission control in integrated services networks1, the Priority Token Bank (PTB), whose mechanism and performance have been studied in a single queue, and extends the algorithm to address the challenges of implementing it in a network of queues. An integrated services network must handle traffic streams with disparate arrival processes and performance objectives, and efficiently supporting these streams becomes more difficult when performance guarantees must be met across a number of switches and when a stream’s burstiness can dramatically increase from source to destination. Three variations on the basic mechanism are proposed to address this problem: PTB-Separate Classes, PTB - Minimum Interdeparture Time, and PTB-Weighted Fair Queuing. It is shown that the PTB scales well to a network of queues, and that, under the constraint that performance requirements for guaranteed traffic such as packet voice, HDTV, and packet video must be met, the mean delay experienced by other traffic is much better with the Priority Token Bank mechanisms than with other proposed algorithms.

description: I was born May 1938 in Balham, South London. My first memory of the war is asking my Mum what all the banging was on Clapham Common, just up the road. She told me it was soldiers practising...which in a way was true.Next memory being wrapped in an eiderdown and with my cousin put under the dining room table while the bombs came down. Two houses disappeared with their occupants one night. We just accepted it as our life.I went to school at the age of three, we could not go in if there was an alert so my Dad took me home. My Mum took me shopping. We stopped at the newsagents round the corner from our house and Mum ordered two comics to be delivered to our house for me, Beano and Dandy. We had got about 75 yards up Balham High Road when we heard the dreaded noise of a doodlebug, and the silence just before it hit the shop we had just left killing everyone in it. I vividly remember my Mum bending over me to shield me.Of course I helped by screaming! Well you would wouldn't you?A plate glass window of Holdrens, a big shop we were standing by, was blasted inwards instead of out, when it would have covered us in glass and the contents of the display. Somehow we got home to find our house had been impacted from the blast: no windows, doors, ceilings or floors and no Pickles the dog. I never got my comics.I can also remember another bomb leaving a deep crater outside Balham underground station, a red double decker nose dived into the hole. It became a very famous photograph.So many bombs, destroying the theatre, the Salvation Army building and many houses in our small part of London. Not to mention the many lives lost and lives ruined.That was my life. I thought that WAS what normal life was all about.

description: We consider an extended spatial autoregressive model that can incorporate possible endogenous interactions, exogenous interactions, unobserved group fixed effects and the correlation of unobservables. In the generalized method of moments (GMM) and the maximum likelihood (ML) frameworks, we introduce simple gradient-based robust test statistics that can be used to test for the presence of the endogenous effects, the correlation of unobservables and the contextual effects. These test statistics are robust to local parametric misspecifications and only require consistent estimates from a transformed linear regression model to compute. We carry out an extensive Monte Carlo study to investigate the size and power properties of the proposed tests. The results show that the proposed tests have good finite sample properties, and are useful for testing the presence of the various effects in a social interaction model.
X-ray Hardness Evolution in GRB Afterglows and Flares: Late Time GRB Activity Without N_H Variations

description: We show that the X-ray and $γ$-ray spectra of Swift GRBs and their afterglows are consistent with the emission characteristic of an expanding, relativistic fireball. The classical afterglow due to the impact of the fireball on the external medium is often not observed until one to several hours after the GRB. Focusing on GRBs 061121, 060614, and 060124, but generalizing to the full ($>$50 Msec XRT exposure) Swift sample up to and including GRB061210, we show that the early emission in $>$90% of early afterglows has a characteristic $νF_ν$ spectral energy $E_{\rm peak}$ which likely evolves from the $γ$-rays through the soft X-ray band on timescales of $10^2-10^4$s after the GRB. The observed spectra are strongly curved when plotted with logarithmic axes and have often been incorrectly fitted in other studies with a time-varying soft X-ray absorption. The spectral evolution inferred from fitting instead models used to fit GRBs demonstrates a common evolution--a powerlaw hardness intensity correlation and hard to soft evolution--for GRBs and the early X-ray afterglows and X-ray flares. Combined with studies of short timescale variability, our findings indicate a central engine active for longer than previously suspected. The GRB spectra are observed to become very soft at late times due to an intrinsic spectral evolution and due to the surprising faintness of some afterglows. We discuss models for the early X-ray emission.
