Black hole accretion disks in the canonical low-hard state
R. C. Reis, A. C. Fabian, J. M. Miller
Stellar-mass black holes in the low-hard state may hold clues to jet formation and basic accretion disk physics, but the nature of the accretion flow remains uncertain. A standard…
X-ray Spectroscopy of the Core of the Perseus Cluster with Suzaku: Elemental Abundances in the Intracluster Medium
Takayuki Tamura, Y. Maeda, K. Mitsuda +7
The results from Suzaku observations of the central region of the Perseus cluster are presented. Deep exposures with the X-ray Imaging Spectrometer provide high quality X-ray spect…
Energetics of a black hole: constraints on the jet velocity and the nature of the X-ray emitting region in Cyg X-1
Julien Malzac, Renaud Belmont, Andrew C. Fabian
We investigate the energetics of the jet and X-ray corona of Cyg X-1. We show that the current estimates of the jet power obtained from Halpha and [O III] measurements of the optic…
A Compton-thick Wind in the High Luminosity Quasar, PDS 456
J. N. Reeves, P. T. O'Brien, V. Braito +7
PDS 456 is a nearby (z=0.184), luminous (L_bol ~10^47 erg/s) type I quasar. A deep 190 ks Suzaku observation in February 2007 revealed the complex, broad band X-ray spectrum of PDS…
The detection of Broad Iron K and L line emission in the Narrow-Line Seyfert 1 Galaxy 1H0707-495 using XMM-Newton
A. C. Fabian, A. Zoghbi, R. R. Ross +14
Since the discovery of the first broad iron-K line in 1995 from the Seyfert Galaxy MCG--6-30-15, broad iron-K lines have been found in several other Seyfert galaxies, from accretin…
Constraints on the absorption-dominated model for the X-ray spectrum of MCG-6-30-15
Christopher S. Reynolds, Andrew C. Fabian, Laura W. Brenneman +3
Complexities in the X-ray spectrum of the nearby Seyfert 1.2 galaxy MCG-6-30-15 are commonly interpreted in terms of a broad iron line and the associated Compton reflection hump fr…
Thermal emission from the stellar-mass black hole binary XTE J1118+480 in the low/hard state
R. C. Reis, J. M. Miller, A. C. Fabian
We report on the detection of a thermal-disk component from the stellar-mass black hole binary XTE J1118+480 in the canonical low/hard state. The presence of a thermal component wi…
XMM-Newton and Suzaku analysis of the Fe K complex in the Seyfert 1 galaxy Mrk 509
G. Ponti, M. Cappi, C. Vignali +11
We report on partially overlapping XMM-Newton (~260 ks) and Suzaku (~100 ks) observations of the iron K band in the nearby, bright Seyfert 1 galaxy Mrk 509. The source shows a reso…
