Importance of Compton scattering to radiation spectra of isolated neutron stars
V. Suleimanov, K. Werner
Model atmospheres of isolated neutron stars with low magnetic field are calculated with Compton scattering taking into account. Models with effective temperatures 1, 3 and 5 MK, wi…
Is the Lack of Pulsations in Low Mass X-Ray Binaries due to Comptonizing Coronae?
Ersin Gogus, M. Ali Alpar, Marat Gilfanov
The spin periods of the neutron stars in most Low Mass X-ray Binary (LMXB) systems still remain undetected. One of the models to explain the absence of coherent pulsations has been…
Neutrino-driven wind and wind termination shock in supernova cores
A. Arcones, L. Scheck, H. -Th. Janka
The neutrino-driven wind from a nascent neutron star at the center of a supernova expands into the earlier ejecta of the explosion. Upon collision with this slower matter the wind…
A Large Stellar Evolution Database for Population Synthesis Studies. III. Inclusion of the full Asymptotic Giant Branch phase and Web tools for stellar population analyses
Daniel Cordier, Adriano Pietrinferni, Santi Cassisi +1
Stellar evolution tracks and isochrones are key inputs for a wide range of astrophysical studies; in particular, they are essential to the interpretation of photometric and spectro…
Extensive multiband study of the X-ray rich GRB 050408. A likely off-axis event with an intense energy injection
A de Ugarte Postigo, T. A. Fatkhullin, G. Johannesson +40
Aims. Understand the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst. Methods. We present a multiband optical light curve, covering the…
Early Ultraviolet, Optical and X-Ray Observations of the Type IIP SN 2005cs in M51 with Swift
Peter J. Brown, Luc Dessart, Stephen T. Holland +14
We report early photospheric-phase observations of the Type IIP Supernova (SN) 2005cs obtained by Swift's Ultraviolet-Optical and X-Ray Telescopes. Observations started within two…
Relativistic inflow in the Seyfert 1 Mrk 335 revealed through X-ray absorption
A. L. Longinotti, S. Sim, K. Nandra +2
The analysis of hard X-ray features in XMM-Newton data of the bright Sy 1 galaxy Mrk 335 is reported here. The presence of a broad, ionised iron K alpha emission line in the spectr…
The Narrow Line Region: Current Models and Future Questions
Brent Groves
I present a broad overview of modelling of the Narrow Line Region (NLR) of active galaxies, and discuss some of the more recent models we currently have for the emission from the N…
New Constraints on Macroscopic Compact Objects as a Dark Matter Candidate from Gravitational Lensing of Type Ia Supernovae
R. Benton Metcalf, Joseph Silk
We use the distribution, and particularly the skewness, of high redshift type Ia supernovae brightnesses relative to the low redshift sample to constrain the density of macroscopic…
Multi-dimensional simulations of radiative transfer in Type Ia supernovae
S. A. Sim
A three-dimensional Monte Carlo code for modelling radiation transport in Type Ia supernovae is described. In addition to tracking Monte Carlo quanta to follow the emission, scatte…
Study of ISM tracers in galaxies
V. Casasola, L. Piovan, G. Galletta +2
We collected data for two samples of normal and interacting galaxies for a total of 2953 galaxies having fluxes in one or more of the following wavebands: FIR, 21 cm line, CO(1-0)…
Theory of Core-Collapse Supernovae
H. -Th. Janka, K. Langanke, A. Marek +2
Advances in our understanding and the modeling of stellar core-collapse and supernova explosions over the past 15 years are reviewed, concentrating on the evolution of hydrodynamic…
Rotating Collapse of Stellar Iron Cores in General Relativity
Christian D. Ott, Harald Dimmelmeier, Andreas Marek +4
We present results from the first 2+1 and 3+1 simulations of the collapse of rotating stellar iron cores in general relativity employing a finite-temperature equation of state and…
Nucleosynthesis-relevant conditions in neutrino-driven supernova outflows. I. Spherically symmetric hydrodynamic simulations
A. Arcones, H. -Th. Janka, L. Scheck
We investigate the behavior and consequences of the reverse shock that terminates the supersonic expansion of the baryonic wind which is driven by neutrino heating off the surface…
The Shape of the Gravitational Potential in Cold Dark Matter Halos
E. Hayashi, J. F. Navarro, V. Springel
We use a set of cosmological N-body simulations to investigate the structural shape of galaxy-sized cold dark matter (CDM) halos. Unlike most previous work on the subject - which d…
COSMOS : Hubble Space Telescope Observations
N. Scoville, A. Benson, A. W. Blain +50
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Her…
Resolving the Galactic X-ray background
M. Revnivtsev, A. Vikhlinin, S. Sazonov
We use Chandra deep observations of the Galactic Center (GC) region to improve the constraints on the unresolved fraction of the Galactic X-ray background (also known as the Galact…
LeMoMaF: Lensed Mock Map Facility
Jaime E. Forero-Romero, Jeremy Blaizot, Julien Devriendt +2
We present the Lensed Mock Map Facility (LeMoMaF), a tool designed to perform mock weak lensing measurements on numerically simulated chunks of the universe. Coupling N-body simula…
