Positron annihilation spectrum from the Galactic Center region observed by SPI/INTEGRAL
E. Churazov, R. Sunyaev, S. Sazonov +2
The electron-positron annihilation spectrum observed by SPI/INTEGRAL during deep Galactic Center region exposure is reported. The line energy (510.9540.075 keV) is consistent…
CFC+: Improved dynamics and gravitational waveforms from relativistic core collapse simulations
P. Cerda-Duran, G. Faye, H. Dimmelmeier +4
Core collapse supernovae are a promising source of detectable gravitational waves. Most of the existing (multidimensional) numerical simulations of core collapse in general relativ…
An optimal filter for the detection of galaxy clusters through weak lensing
M. Maturi, M. Meneghetti, M. Bartelmann +2
We construct a linear filter optimised for detecting dark-matter halos in weak-lensing data. The filter assumes a mean radial profile of the halo shear pattern and modifies that sh…
The Properties of Ultraviolet-Luminous Galaxies at the Current Epoch
Timothy M. Heckman, Charles G. Hoopes, Mark Seibert +23
We have used the first matched set of GALEX and SDSS data to investigate the properties of a sample of 74 nearby galaxies with far-ultraviolet luminosities chosen to overlap the lu…
Ultrahigh Energy Nuclei Propagation in a Structured, Magnetized Universe
Eric Armengaud, Guenter Sigl, Francesco Miniati
We compare the propagation of iron and proton nuclei above 10^19 eV in a structured Universe with source and magnetic field distributions obtained from a large scale structure simu…
The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4
James S. Bolton, Martin G. Haehnelt, Matteo Viel +1
Estimates of the metagalactic hydrogen ionization rate from the Lyman-alpha forest opacity in QSO absorption spectra depend on the complex density distribution of neutral hydrogen…
Multi-Temperature Blackbody Spectrum of a Thin Accretion Disk around a Kerr Black Hole: Model Computations and Comparison with Observations
Li-Xin Li, Erik R. Zimmerman, Ramesh Narayan +1
We use a ray-tracing technique to compute the observed spectrum of a thin accretion disk around a Kerr black hole. We include all relativistic effects such as frame-dragging, Doppl…
Non-parametric mass reconstruction of A1689 from strong lensing data with SLAP
J. M. Diego, H. B. Sandvik, P. Protopapas +3
We present the mass distribution in the central area of the cluster A1689 by fitting over 100 multiply lensed images with the non-parametric Strong Lensing Analysis Package (SLAP,…
Dust coagulation in protoplanetary disks: a rapid depletion of small grains
C. P. Dullemond, C. Dominik
We model the process of dust coagulation in protoplanetary disks and calculate how it affects their observational appearance. Our model involves the detailed solution of the coagul…
Intensity of the cosmic X-ray backgound from HEAO1/A2 experiment
M. Revnivtsev, M. Gilfanov, K. Jahoda +1
We reanalyze data of HEAO1/A2 -- Cosmic X-ray Experiment -- in order to repeat the measurements of the cosmic X-ray background (CXB) intensity and accurately compare this value wit…
Stochastic Gravitational Wave Background from Cosmological Supernovae
Alessandra Buonanno, Guenter Sigl, Georg G. Raffelt +2
Based on new developments in the understanding of supernovae (SNe) as gravitational-wave (GW) sources we estimate the GW background from all cosmic SNe. For a broad range of freque…
Exploiting the neutronization burst of a galactic supernova
M. Kachelriess, R. Tomas, R. Buras +3
One of the robust features found in simulations of core-collapse supernovae (SNe) is the prompt neutronization burst, i.e. the first milliseconds after bounce when the SN…
The DEEP Groth Strip Galaxy Redshift Survey. VIII. The Evolution of Luminous Field Bulges at Redshift z ~ 1
David C. Koo, Luc Simard, Christopher N. A. Willmer +11
We present a sample of over 50 luminous field bulges (including ellipticals) found in the Groth Strip Survey (GSS), with 0.73< z < 1.04 and with bulge magnitudes I <= 23. The expon…
Warped accretion disks and the unification of Active Galactic Nuclei
Sergei Nayakshin
Orientation of parsec-scale accretion disks in AGN is likely to be nearly random for different black hole feeding episodes. Since AGN accretion disks are unstable to self-gravity o…
XMM-Newton detects the beginning of the X-ray decline of SN 1995N
P. Mucciarelli, L. Zampieri, A. Pastorello
We present the results of a new XMM-Newton observation of the interacting supernova 1995N, performed on July 27, 2003. We find that the 0.2-10.0 keV flux has dropt at a level of 1.…
Constraints on the luminosity of the stellar remnant in SNR1987A
P. Shtykovskiy, A. Lutovinov, M. Gilfanov +1
We obtain photometric constraints on the luminosity of the stellar remnant in SNR1987A using XMM-Newton and INTEGRAL data. The upper limit in the 2--10 keV band based on the XMM-Ne…
The broad-band spectrum of the persistent emission from SGR1806-20
S. Molkov, K. Hurley, R. Sunyaev +2
We present the results of an analysis of the quiescent X-ray emission from the Soft Gamma-Ray Repeater SGR1806-20, taken during an INTEGRAL ultra-deep survey of the Galactic Center…
The distributed burning regime in Type Ia supernova models
F. K. Roepke, W. Hillebrandt
The deflagration mode of flame propagation in Type Ia supernova (SN Ia) models requires a correct description of the interaction of the flame with turbulent motions. It is well-kno…
High velocity features in the spectra of the Type Ia SN 1999ee: a property of the explosion or evidence of circumstellar interaction?
P. A. Mazzali, S. Benetti, M. Stehle +5
The near-maximum spectra of the Type Ia SN 1999ee are reviewed. Two narrow absorption features corresponding to the strongest component of the CaII IR triplet appear in the spectra…
Abundance of substructure in clusters of galaxies
Priyamvada Natarajan, Volker Springel
It is widely recognized that cold dark matter models predict abundant dark matter substructure in halos of all sizes. Galaxy-galaxy lensing provides a unique opportunity to directl…
