The XMM-Newton long look of NGC 1365: uncovering of the obscured X-ray source
G. Risaliti, M. Salvati, M. Elvis +10
We present an analysis of the extreme obscuration variability observed during an XMM-Newton 5-days continuous monitoring of the AGN in NGC 1365. The source was in a reflection-domi…
A systematic look at the Very High and Low/Hard state of GX 339-4: Constraining the black hole spin with a new reflection model
R. C. Reis, A. C. Fabian, R. Ross +3
We present a systematic study of GX 339-4 in both its very high and low hard states from simultaneous observations made with XMM-Newton and RXTE in 2002 and 2004. The X-ray spectra…
Weighing the black holes in ultraluminous X-ray sources through timing
P. Casella, G. Ponti, A. Patruno +3
We describe a new method to estimate the mass of black holes in Ultraluminous X-ray Sources (ULXs). The method is based on the recently discovered ``variability plane'', populated…
Initial Measurements of Black Hole Spin in GX 339-4 from Suzaku Spectroscopy
J. M. Miller, C. S. Reynolds, A. C. Fabian +6
We report on a deep Suzaku observation of the stellar-mass black hole GX 339-4 in outburst. A clear, strong, relativistically-shaped iron emission line from the inner accretion dis…
Suzaku observations of Markarian 335: evidence for a distributed reflector
J. Larsson, G. Miniutti, A. C. Fabian +3
We report on a 151 ks net exposure Suzaku observation of the Narrow Line Seyfert 1 galaxy Mrk 335. The 0.5-40 keV spectrum contains a broad Fe line, a strong soft excess below abou…
Constraints on light bending and reflection from the hard X-ray background
P. Gandhi, A. C. Fabian, T. Suebsuwong +3
Light bending due to strong gravity has recently been invoked to explain variability and flux correlations between different bands in some accreting black holes. A characteristic f…
