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…
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…
A Search for New Galactic Magnetars in Archival Chandra and XMM-Newton Observations
M. P. Muno, B. M. Gaensler, A. Nechita +2
We present constraints on the number of Galactic magnetars, which we have established by searching for sources with periodic variability in 506 archival Chandra observations and 44…
Observations of the 599 Hz Accreting X-ray Pulsar IGR J00291+5934 during the 2004 Outburst and in Quiescence
M. A. P. Torres, P. G. Jonker, D. Steeghs +10
We report on optical and NIR observations obtained during and after the 2004 December discovery outburst of the X-ray transient and accretion-powered millisecond pulsar IGR J00291+…
