The high-energy emission from GX 339-4 as seen with INTEGRAL and XMM-Newton
M. D. Caballero-Garcia, J. M. Miller, A. C. Fabian
GX 339--4 is a well-known microquasar. In this contribution we show the obtained results with the INTEGRAL and XMM-Newton observatories of the outburst undertaken on 2007. The obse…
INTEGRAL and XMM-Newton Spectroscopy of GX 339-4 During Hard/Soft Intermediate and High/Soft States in the 2007 Outburst
M. D. Caballero-Garcia, J. M. Miller, M. Diaz Trigo +5
We present simultaneous XMM-Newton and INTEGRAL observations of the luminous black hole transient and relativistic jet source GX 339-4. GX 339-4 started an outburst on November of…
A Deep XMM-Newton Observation of the Quasar 3C 287
G. Salvesen, J. M. Miller, E. Cackett +1
We report on an XMM-Newton observation of the z=1.055 quasar and Giga-hertz Peaked Spectrum (GPS) source 3C 287. Our 62.3 ksec observation provides an exceptional X-ray view of a p…
Rapid optical and X-ray timing observations of GX 339-4: flux correlations at the onset of a low/hard state
P. Gandhi, K. Makishima, M. Durant +6
We present the discovery of optical/X-ray flux correlations on rapid timescales in the low/hard state of the Galactic black hole GX 339-4. The source had recently emerged from outb…
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…
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…
