Peering Through the Muck: Notes on the Influence of the Galactic Interstellar Medium on Extragalactic Observations

description: This paper considers some effects of foreground Galactic gas on radiation received from extragalactic objects, with an emphasis on the use of the 21cm line to determine the total N(HI). In general, the opacity of the 21cm line makes it impossible to derive an accurate value of N(HI) by simply applying a formula to the observed emission, except in directions where there is very little interstellar matter. The 21cm line can be used to estimate the likelihood that there is significant molecular hydrogen in a particular direction, but carries little or no information on the amount of ionized gas, which can be a major source of foreground effects. Considerable discussion is devoted to the importance of small-scale angular structure in HI, with the conclusion that it will rarely contribute significantly to the total error compared to other factors (such as the effects of ionized gas) for extragalactic sight lines at high Galactic latitude. The direction of the Hubble/Chandra Deep Field North is used as an example of the complexities that might occur even in the absence of opacity or molecular gas.

description: A new class of exact solutions of Einstein's field equations with perfect fluid for an LRS Bianchi type-I spacetime is obtained by using a time dependent deceleration parameter. We have obtained a general solution of the field equations from which three models of the universe are derived: exponential, polynomial and sinusoidal form respectively. The behaviour of these models of the universe are also discussed in the frame of reference of recent supernovae Ia observations.

description: Through the use of selected works by Philip K. Dick, Robert Heinlein, Frank Herbert and H.P. Lovecraft, this thesis explores the question of what it means to be human in the universe when occidental cosmologies no longer align with the universe they seek to describe. Within its view of the universe, H.P. Lovecraft’s philosophy of cosmicism offers the human creature an answer to this question, but in doing so also limits that creature to an isolated life ending in madness or death within an indifferently cold universe.
While this thesis seeks to demonstrate the validity of cosmicism as a lens through which to critically interrogate science fiction texts; it more importantly endeavours to address cosmicism’s inherent limitations as a philosophy of the human creature’s place in the universe. This is done by developing neocosmicism as an outgrowth of cosmicism that offers an alternate experience of the universe and a revitalisation of the human creature’s relationship with the universe. By recognising the significant shift in the human creature’s understanding of the universe – from a Cartesian view to a Quantum view within a broader post-modern context – neocosmicism is developed as an interrogative philosophy that provides a framework for opening up a critical space in which to explore alternatives to modernity’s questions rather than offering mere reactions or polarising oppositions.
For neocosmicism, this thesis represents a beginning, and in no way provides a comprehensive development or analysis of its nuances. At this early stage of development, neocosmicism asks more questions than it answers; suspects that god and the void are a manifest singularity that is the universe; and suggests that cosmicism’s limiting outcome of estrangement between the human creature and the universe can be transformed to a vitalised outcome of relationship between the emotive biological creature [that the human creature is] and the indifferently cold chaos that creature calls the universe.

description: Hard X-rays observed in Active Galactic Nuclei (AGNs) are thought to originate from the Comptonization of the optical/UV accretion disk photons in a hot corona. Polarization studies of these photons can help to constrain the corona geometry and the plasma properties. We have developed a ray-tracing code that simulates the Comptonization of accretion disk photons in coronae of arbitrary shape, and use it here to study the polarization of the X-ray emission from wedge and spherical coronae. We study the predicted polarization signatures for the fully relativistic and various approximate treatments of the elemental Compton scattering processes. We furthermore use the code to evaluate the impact of non-thermal electrons and cyclo-synchrotron photons on the polarization properties. Finally, we model the NuSTAR observations of the Seyfert I galaxy Mrk 335 and predict the associated polarization signal. Our studies show that X-ray polarimetry missions such as NASA's Imaging X-ray Polarimetry Explorer (IXPE) and the X-ray Imaging Polarimetry Explorer (XIPE) proposed to ESA will provide valuable new information about the physical properties of the plasma close to the event horizon of AGN black holes.

description: We study the emergence and the stability of temporal localized structures in the output of a semiconductor laser passively mode-locked by a saturable absorber in the long cavity regime. For large yet realistic values of the linewidth enhancement factor, we disclose the existence of secondary dynamical instabilities where the pulses develop regular and subsequent irregular temporal oscil- lations. By a detailed bifurcation analysis we show that additional solution branches that consist in multi-pulse (molecules) solutions exist. We demonstrate that the various solution curves for the single and multi-peak pulses can splice and intersect each other via transcritical bifurcations, lead- ing to a complex web of solution. Our analysis is based upon a generic model of mode-locking that consists in a time-delayed dynamical system, but also upon a much more numerically efficient, yet approximate, partial differential equation. We compare the results of the bifurcation analysis of both models in order to assess up to which point the two approaches are equivalent. We conclude our analysis by the study of the influence of group velocity dispersion, that is only possible in the framework of the partial differential equation model, and we show that it may have a profound impact on the dynamics of the localized states.

description: Trend removal is an important problem in most communication systems. Here, we show a proposed algorithm for trend (background) removal from Raman Spectra by merging local variance estimation and cubic spline interpolation methods. We found that Raman spectrum does not need a smoothing process to remove trend from noisy signals. Employing this technique results in more speedy and noiseless systems than other techniques that use wavelet transformation to suppress noise.

 Rhizogeton L. Agassiz, 1862: 224.
 Type species. Rhizogeton fusiformis L. Agassiz, 1862, by monotypy.
 Diagnosis. Oceaniid hydroids with stolonal colonies. Hydranths arising from hydrorhiza, with thin perisarcal collar at base, varied in shape but nearly cylindrical when extended; tentacles filiform, scattered over much of hydranth; hypostome conical.
Gonophores fixed sporosacs, borne on hydrorhiza.
 Remarks. The genus Rhizogeton L. Agassiz, 1862 is distinguished from other oceaniid hydroids in having stolonal colonies with fixed gonophores that arise only from the hydrorhiza, and in lacking nematophores. Rhizodendrium Calder, 1988 has been considered a synonym (Schuchert 2004; Bouillon et al. 2006), and I agree. Rhizodendrium was established after comparing R. sterreri Calder, 1988 from Bermuda with incompletely described and poorly preserved type material of Rhizogeton fusiformis L. Agassiz, 1862, type species of Rhizogeton, from Massachusetts. The diagram and description of the hydranth of R. fusiformis in L. Agassiz (1862: 224–226, Plate 20) must be considered misleading based on subsequent observations of the species. Abundant fertile colonies identified as R. fusiformis from Passamaquoddy Bay, Canada (ROMIZ B3101, ROMIZ B3102) generally overlap Rhizodendrium sterreri in important characters such as hypostome shape, tentacle numbers and arrangement, and gonophore morphology, the reasons originally given for establishing Rhizodendrium as a distinct genus.
 Five species are currently recognized in the genus Rhizogeton (Schuchert 2009). Possible undescribed species have been noted in both the Indian Ocean (Gravier-Bonnet & Mioche 1996) and in European waters (Schuchert 2008a: 273–274). Hydroids of Rhizogeton are mostly inconspicuous and poorly known, but they now appear to be notably widespread. Representatives have been reported from the Atlantic, Pacific, Indian, and Arctic oceans, and some are known to raft on phoretic substrates such as pelagic Sargassum (Calder 1988, 1995).

description: We present a unique set of nested stellar kinematical maps of NGC 3377 obtained with the integral-field spectrographs OASIS and SAURON. We then construct general axisymmetric dynamical models for this galaxy, based on the Schwarzschild numerical orbit superposition technique applied to these complementary measurements. We show how these two datasets constrain the mass of the central massive object and the overall mass-to-light ratio of the galaxy by probing the inner and outer regions respectively. The simultaneous use of both datasets leads us to confirm the presence of a massive black hole with a mass of $M_{BH} = 7_{-5}^{+4} 10^{7} M_\sun$ (99.7% confidence level), with a best-fit stellar mass-to-light ratio $Υ_I = 2.1 \pm 0.2$ (for an assumed edge-on inclination).

description: Single-electron transistors would represent an approach for less power consuming microelectronic devices if room-temperature operation and industry-compatible fabrication were possible. We present a concept based on stripes of small, self-assembled, colloidal, metal nanoparticles on a back-gate device architecture which leads to well-defined and well-controllable transistor characteristics. This Coulomb transistor has three main advantages: By employing the scalable Langmuir-Blodgett method we combine high-quality chemically synthesized metal nanoparticles with standard lithography techniques. The resulting transistors show on/off ratios above 90 %, reliable and sinusoidal Coulomb oscillations and room-temperature operation. Furthermore, this concept allows for versatile tuning of the device properties like Coulomb-energy gap, threshold voltage, as well as period, position and strength of the oscillations.

description: Genus Turritopsis McCrady, 1857
 Turritopsis McCrady, 1857: 58.
 Type species. Turritopsis nutricula McCrady, 1857, by monotypy.
 Diagnosis. Oceaniid hydroids sometimes stolonal but usually with erect and irregularly branched colonies. Hydrocaulus polysiphonic or less frequently monosiphonic, branched or less often simple; hydrocladia, if present, adnate to hydrocaulus or to other hydrocladia over part of their length basally. Perisarc with firm outer primary and more filmy inner secondary layers, covering hydrocauli and hydrocladia, terminating near hydranth bases. Hydranths club-shaped, lacking perisarc; tentacles filiform, scattered over most of hydranth.
Gonophores, where known, free medusae, borne on pedicels or branches. Medusa thimble-shaped; radial canals surrounded by mass of vacuolated cells at apex of manubrium; marginal tentacles solitary, simple, eight or more; ocelli present.
 Remarks. With the publication date of McCrady’s account of Turritopsis established as 1857 instead of 1859 (Calder et al. 1992), earlier concerns (Calder 1988) that this familiar generic name was threatened by the nearly forgotten Clavula Wright, 1859a are removed.
 Transformation of medusae into polyps has been described in species of this genus (Bavastrello et al. 1992; Piraino et al. 1996). Although reported relatively infrequently, this peculiar phenomenon has been known for more than a century. Hincks (1865) reported it in a hydractiniid, and other early accounts of such “retrograde metamorphosis” were reviewed by Hincks (1868: xxviii–xxix).

description: General relativity successfully describes space-times at scales that we can observe and probe today, but it cannot be complete as a consequence of singularity theorems. For a long time there have been indications that quantum gravity will provide a more complete, non-singular extension which, however, was difficult to verify in the absence of a quantum theory of gravity. By now there are several candidates which show essential hints as to what a quantum theory of gravity may look like. In particular, loop quantum gravity is a non-perturbative formulation which is background independent, two properties which are essential close to a classical singularity with strong fields and a degenerate metric. In cosmological and black hole settings one can indeed see explicitly how classical singularities are removed by quantum geometry: there is a well-defined evolution all the way down to, and across, the smallest scales. As for black holes, their horizon dynamics can be studied showing characteristic modifications to the classical behavior. Conceptual and physical issues can also be addressed in this context, providing lessons for quantum gravity in general. Here, we conclude with some comments on the uniqueness issue often linked to quantum gravity in some form or another.

description: As first demonstrated by Tang and Cohen in chiral optics, the asymmetry in the rate of electromagnetic energy absorption between left and right enantiomers is determined by an optical chirality density [1]. Here, we demonstrate that this effect can exist in magnetic spin systems. By constructing a formal analogy with electrodynamics, we show that in antiferromagnets with broken chiral symmetry the asymmetry in local spin-wave energy absorption is proportional to a spin-wave chirality density, which is a direct counterpart of optical zilch. We propose that injection of a pure spin current into an antiferromagnet may serve as a chiral symmetry breaking mechanism, since its effect in the spin-wave approximation can be expressed in terms of additional Lifshitz invariants. We use linear response theory to show that the spin current induces a nonequilibrium spin-wave chirality density.

We assumed that the electromagnetic field is in different states such as coherent, squeezed vacuum and pair coherent, and that the atom is initially in the excited state. We studied the temporal evolution of the population of the excited level, and the second order coherence function. The results obtained show that this system has some similarities with the two-mode Stark system. We analize two photon entanglement for different initial conditions.

description: We introduce in this paper an exact solvable BCS-Hubbard model in arbitrary dimensions. The model describes a p-wave BCS superconductor with equal spin pairing moving on a bipartite (cubic, square etc.) lattice with on site Hubbard interaction $U$. We show that the model becomes exactly solvable for arbitrary $U$ when the BCS pairing amplitude $Δ$ equals the hopping amplitude $t$. The nature of the solution is described in detail in this paper. The construction of the exact solution is parallel to the exactly solvable Kitaev honeycomb model for $S=1/2$ quantum spins and can be viewed as a generalization of Kitaev's construction to $S=1/2$ interacting lattice fermions. The BCS-Hubbard model discussed in this paper is just an example of a large class of exactly solvable lattice fermion models that can be constructed similarly.

description: Family Cordylophoridae von Lendenfeld, 1885  Cordylophorinae von Lendenfeld, 1885: 221.
 Diagnosis. Filiferan hydroids with erect, monopodial colonies; arising from a creeping hydrorhiza. Hydrocaulus branched, with hydrocladia given off immediately from hydrocaulus rather than being adnate to it for a varying distance basally; perisarc enveloping hydrocauli, hydrocladia, pedicels, and hydrorhiza, not extending over hydranths as a pseudohydrotheca. Hydranths spindle-shaped; tentacles filiform, scattered over hydranth body; hypostome conical to nipple-shaped.
Gonophores fixed sporosacs, borne on hydrocladia and hydranth pedicels; spadix branched.
 Remarks. Cordylophoridae von Lendenfeld, 1885 was originally established as a subfamily (Cordylophorinae) within Clavidae McCrady 1859. Two genera were originally included in it, Cordylophora Allman, 1843 and Merona Norman, 1865. In having polymorphic hydranths and nematophores, however, Merona differs significantly from Cordylophora and was removed from Cordylophorinae (Calder 1988). The single remaining genus Cordylophora has been assigned in most recent works to Oceaniidae Eschscholtz, 1829. Cordylophoridae has been recognized as valid in the World Hydrozoa Database, but its recognition may be temporary because molecular studies on Cordylophora suggest an affinity with Bougainvilliidae Lütken, 1850 (Schuchert 2009). As for Clavidae, its type genus (Clava Gmelin, 1791) is now known to be a hydractiniid (see Remarks above under family Oceaniidae).

description: Defects and their interactions in crystalline solids often underpin material properties and functionality as they are decisive for stability, result in enhanced diffusion, and act as a reservoir of vacancies. Recently, lithium-rich layered oxides have emerged among the leading candidates for the next-generation energy storage cathode material, delivering 50 % excess capacity over commercially used compounds. Oxygen-redox reactions are believed to be responsible for the excess capacity, however, voltage fading has prevented commercialization of these new materials. Despite extensive research the understanding of the mechanisms underpinning oxygen-redox reactions and voltage fade remain incomplete. Here, using operando three-dimensional Bragg coherent diffractive imaging, we directly observe nucleation of a mobile dislocation network in nanoparticles of lithium-rich layered oxide material. Surprisingly, we find that dislocations form more readily in the lithium-rich layered oxide material as compared with a conventional layered oxide material, suggesting a link between the defects and the anomalously high capacity in lithium-rich layered oxides. The formation of a network of partial dislocations dramatically alters the local lithium environment and contributes to the voltage fade. Based on our findings we design and demonstrate a method to recover the original high voltage functionality. Our findings reveal that the voltage fade in lithium-rich layered oxides is reversible and call for new paradigms for improved design of oxygen-redox active materials.

description: We present a model of a pulsar wind nebula evolving inside its associated supernova remnant. The model uses a hydrodynamics code to simulate the evolution of this system when the pulsar has a high velocity. The simulation distinguishes four different stages of pulsar wind nebula evolution: the supersonic expansion stage, the reverse shock interaction stage, the subsonic expansion stage and ultimately the bow shock stage. The simulation bears out that, due to the high velocity of the pulsar, the position of the pulsar is off-centered with respect to its pulsar wind nebula, after the passage of the reverse shock. Subsequently the pulsar wind nebula expands subsonically untill the event of the bow shock formation, when the motion of the pulsar becomes supersonic. The bow shock formation event occurs at roughly half the crossing time, when the pulsar is positioned at 0.677 times the radius of the supernova remnant blastwave, in complete agreement with analytical predictions. The crossing time is defined by the age of the supernova remnant, when the pulsar overtakes the blastwave bounding the supernova remnant. The results of the model are applied to three supernova remnants: N157B, G327.1-1.1 and W44. We argue that the head of the pulsar wind nebula, containing the active pulsar, inside the first two systems are not bounded by a bow shock. However, in the case of W44 we argue for a scenario in which the pulsar wind nebula is bounded by a bow shock, due to the supersonic motion of the pulsar.

description: Quantum corrections to the classical field equations, induced by a scale dependent gravitational constant, are analyzed in the case of the static isotropic metric. The requirement of general covariance for the resulting non-local effective field equations puts severe restrictions on the nature of the solutions that can be obtained. In general the existence of vacuum solutions to the effective field equations restricts the value of the gravitational scaling exponent $ν^{-1}$ to be a positive integer greater than one. We give further arguments suggesting that in fact only for $ν^{-1}=3$ consistent solutions seem to exist in four dimensions.

description: The Milagro telescope monitors the northern sky for 100 GeV to 100 TeV transient emission through continuous very high energy wide-field observations. The large effective area and ~100 GeV energy threshold of Milagro allow it to detect very high energy (VHE) gamma-ray burst emission with much higher sensitivity than previous instruments and a fluence sensitivity at VHE energies comparable to that of dedicated gamma-ray burst satellites at keV to MeV energies. Even in the absence of a positive detection, VHE observations can place important constraints on gamma-ray burst (GRB) progenitor and emission models. We present limits on the VHE flux of 40 s -- 3 h duration transients nearby to earth, as well as sensitivity distributions which have been corrected for gamma-ray absorption by extragalactic background light and cosmological effects. The sensitivity distributions suggest that the typical intrinsic VHE fluence of GRBs is similar or weaker than the keV -- MeV emission, and we demonstrate how these sensitivity distributions may be used to place observational constraints on the absolute VHE luminosity of gamma-ray bursts for any GRB emission and progenitor model.

description: We systematically study a Kitaev chain with imbalanced pair creation and annihilation, which is introduced by non-Hermitian pairing terms. Exact phase diagram shows that the topological phase is still robust under the influence of the conditional imbalance. The gapped phases are characterized by a topological invariant, the extended Zak phase, which is defined by the biorthonormal inner product. Such phases are destroyed at the points where the coalescence of groundstates occur, associating with the time-reversal symmetry breaking. We find that the Majorana edge modes also exist for the open chain within unbroken time-reversal symmetric region, demonstrating the bulk-edge correspondence in such a non-Hermitian system.

Observable Effects of Scalar Fields and Varying Constants

description: We show by using the method of matched asymptotic expansions that a sufficient condition can be derived which determines when a local experiment will detect the cosmological variation of a scalar field which is driving the spacetime variation of a supposed constant of Nature. We extend our earlier analyses of this problem by including the possibility that the local region is undergoing collapse inside a virialised structure, like a galaxy or galaxy cluster. We show by direct calculation that the sufficient condition is met to high precision in our own local region and we can therefore legitimately use local observations to place constraints upon the variation of "constants" of Nature on cosmological scales.

description: We report three new barium (Ba) dwarfs lying in Sirius-like systems, which provides direct evidence that Ba dwarfs are companions to white dwarfs (WDs). Atmospheric parameters, stellar masses, and chemical abundances of 25 elements, including light, $α$, Fe-peak and s-process elements, are derived from high resolution and high S/N spectra. Enhancement of s-process elements with [s/Fe] ratios between 0.4 and 0.6 confirm them as mild barium stars. The estimated metallicities ($-$0.31, $-$0.06, 0.13) of BD+68$^\circ$1027, RE~J0702+129 and BD+80$^\circ$670 are in the range of known Ba dwarfs and giants. As expected, observed indices of [hs/ls], [s/Fe] and [C/Fe] show anticorrelation with metallicity. AGB progenitor masses are estimated for the WD companions of RE~J0702+129 (1.47 $M_{\odot}$) and BD+80$^\circ$670 (3.59 $M_{\odot}$), which confirms the predicted range of progenitor AGB masses (1.5 $\sim$ 4 $M_{\odot}$) for unseen WDs around Ba dwarfs. Surface abundances of s-process elements in RE~J0702+129 and BD+80$^\circ$670 are compared with AGB models and they are in close agreement, within predicted accretion efficiencies and pollution factors for Ba stars. These results support that the origin of s-process overabundances in Ba dwarfs is similar to Ba giants via McClure hypothesis in which Ba stars accumulate s-process elements through mass transfer from their host companions during AGB phase.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

X-ray Reflection from Inhomogeneous Accretion Disks: I. Toy Models and Photon Bubbles

description: Numerical simulations of the interiors of radiation dominated accretion disks show that significant density inhomogeneities can be generated in the gas. Here, we present the first results of our study on X-ray reflection spectra from such heterogeneous density structures. We consider two cases: first, we produce a number of toy models where a sharp increase or decrease in density of variable width is placed at different depths in a uniform slab. Comparing the resulting reflection spectra to those from an unaltered slab shows that the inhomogeneity can affect the emission features, in particular the Fe K and O VIII Lyalpha lines. The magnitude of any differences depends on both the parameters of the density change and the ionizing power of the illuminating radiation, but the inhomogeneity is required to be within ~2 Thomson depths of the surface to cause an effect. However, only relatively small variations in density (on the order of a few) are necessary for significant changes in the reflection features to be possible. Our second test was to compute reflection spectra from the density structure predicted by a simulation of the non-linear outcome of the photon bubble instability. The resulting spectra also exhibited differences from the constant density models, caused primarily by a strong 6.7 keV iron line. Nevertheless, constant density models can provide a good fit to simulated spectra, albeit with a low reflection fraction, between 2 and 10 keV. Below 2 keV, differences in the predicted soft X-ray line emission result in very poor fits with a constant density ionized disk model. The results indicate that density inhomogeneities may further complicate the relationship between the Fe K equivalent width and the X-ray continuum.

description: A controlled decoherence environment is studied experimentally by free electron interaction with semiconducting and metallic plates. The results are compared with physical models based on decoherence theory to investigate the quantum-classical transition. The experiment is consistent with decoherence theory and rules out established Coulomb interaction models in favor of plasmonic excitation models. In contrast to previous decoherence experiments, the present experiment is sensitive to the onset of decoherence.
