Corona, Jet, and Relativistic Line Models for Suzaku/RXTE/Chandra-HETG Observations of the Cygnus X-1 Hard State
Michael A. Nowak, Manfred Hanke, Sarah N. Trowbridge +7
Using Suzaku and the Rossi X-ray Timing Explorer, we have conducted a series of four simultaneous observations of the galactic black hole candidate Cyg X-1 in what were historicall…
4U 1909+07: a well-hidden pearl
F. Fuerst, I. Kreykenbohm, S. Suchy +4
We present the first detailed spectral and timing analysis of the High Mass X-ray Binary (HMXB) 4U 1909+07 with INTEGRAL and RXTE. 4U 1909+07 is detected in the ISGRI 20-40 keV ene…
Is the plateau state in GRS 1915+105 equivalent to canonical hard states?
Pieter van Oers, Sera Markoff, Dipankar Maitra +7
GRS1915+105 is a very peculiar black hole binary that exhibits accretion-related states that are not observed in any other stellar-mass black hole system. One of these states, howe…
Broad emission lines for negatively spinning black holes
T. Dauser, J. Wilms, C. S. Reynolds +1
We present an extended scheme for the calculation of the profiles of emission lines from accretion discs around rotating black holes. The scheme includes discs with angular momenta…
NLTE model atmospheres for the hottest white dwarfs: Spectral analysis of the compact component in nova V4743 Sgr
T. Rauch, M. Orio, R. Gonzales-Riestra +4
Half a year after its outburst in September 2002, nova V4743 Sgr evolved into the brightest supersoft X-ray source in the sky with a flux maximum around 30A. We calculated grids of…
The gamma-ray properties of radio-selected extragalactic jets
M. Boeck, M. Kadler, G. Tosti +4
Most extragalactic jets in radio-loud Active Galactic Nuclei are bright and variable gamma-ray sources, which are continuously monitored with Fermi/LAT. We present the gamma-ray pr…
X-ray variation statistics and wind clumping in Vela X-1
Felix Fürst, Ingo Kreykenbohm, Katja Pottschmidt +8
We investigate the structure of the wind in the neutron star X-ray binary system Vela X-1 by analyzing its flaring behavior. Vela X-1 shows constant flaring, with some flares reach…
RXTE observations of the 1A 1118-61 in an outburst, and the discovery of a cyclotron line
V. Doroshenko, S. Suchy, A. Santangelo +5
We present the analysis of RXTE monitoring data obtained during the January 2009 outburst of the hard X-ray transient 1A 1118-61. Using these observations the broadband (3.5-120 ke…
TANAMI: Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry I. First-Epoch 8.4 GHz Images
Roopesh Ojha, Matthias Kadler, Moritz Böck +24
We introduce the TANAMI program (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) which is monitoring an initial sample of 43 extragalactic jets located…
INTEGRAL deep observations of the Small Magellanic Cloud
M. J. Coe, A. J. Bird, D. A. H. Buckley +12
Deep observations of the Small Magellanic Cloud (SMC) and region were carried out in the hard X-ray band by the INTEGRAL observatory in 2008-2009. The field of view of the instrume…
A Thorough Look at the Photoionized Wind and Absorption Dips in the Cygnus X-1 / HDE 226868 X-ray Binary System
Manfred Hanke, Jörn Wilms, Michael A. Nowak +4
We present results from simultaneous observations of the high-mass X-ray binary system Cygnus X-1 / HDE 226868 with Suzaku, Chandra-HETGS, XMM-Newton, RXTE, INTEGRAL, and Swift in…
Peculiar outburst of A 0535+26 observed with INTEGRAL, RXTE and Suzaku
I. Caballero, K. Pottschmidt, L. Barragan +17
A normal outburst of the Be/X-ray binary system A0535+26 has taken place in August 2009. It is the fourth in a series of normal outbursts that have occured around the periastron pa…
The Double-Degenerate Nucleus of the Planetary Nebula TS 01. A Close Binary Evolution Showcase
Gagik Tovmassian, Lev Yungelson, Thomas Rauch +8
We present a detailed investigation of SBS1150+599A, a close binary star hosted by the planetary nebula PN G135.9+55.9 (TS01, Stasinska et al, 2009). The nebula, located in the Gal…
eROSITA on SRG
Peter Predehl, Hans Boehringer, Hermann Brunner +25
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the core instrument on the Russian Spektrum-Roentgen-Gamma (SRG) mission which is scheduled for launch in late…
