Broadband X-ray spectral analysis of the Seyfert 1 galaxy GRS 1734-292
A. Tortosa, A. Marinucci, G. Matt +14
We discuss the broadband X-ray spectrum of GRS 1734-292 obtained from non-simultaneous XMM-Newton and NuSTAR observations, performed in 2009 and 2014, respectively. GRS1734-292 is…
The nova-like nebular optical spectrum of V404 Cygni at the beginning of the 2015 outburst decay
F. Rahoui, J. A. Tomsick, P. Gandhi +7
We report on FORS2 optical spectroscopy of the black hole X-ray binary V404 Cygni, performed at the very beginning of its 2015 outburst decay, complemented by quasi-simultaneous $S…
Spectral Changes in the Hyperluminous Pulsar in NGC 5907 as a Function of Super-Orbital Phase
F. Fuerst, D. J. Walton, D. Stern +5
We present broad-band, multi-epoch X-ray spectroscopy of the pulsating ultra-luminous X-ray source (ULX) in NGC 5907. Simultaneous XMM-Newton and NuSTAR data from 2014 are best des…
Detection of Very Low-Frequency Quasi-Periodic Oscillations in the 2015 Outburst of V404 Cygni
D. Huppenkothen, G. Younes, A. Ingram +12
In June 2015, the black hole X-ray binary (BHXRB) V404 Cygni went into outburst for the first time since 1989. Here, we present a comprehensive search for quasi-periodic oscillatio…
GRS 1739-278 observed at very low luminosity with XMM-Newton and NuSTAR
F. Fuerst, J. A. Tomsick, K. Yamaoka +19
We present a detailed spectral analysis of XMM-Newton and NuSTAR observations of the accreting transient black hole GRS 1739-278 during a very faint low hard state at ~0.02% of the…
NuSTAR Observations of the Black Hole GS 1354-645: Evidence of Rapid Black Hole Spin
A. M. El-Batal, J. M. Miller, M. T. Reynolds +10
We present the results of a NuSTAR study of the dynamically confirmed stellar-mass black hole GS 1354-645. The source was observed during its 2015 "hard" state outburst; we concent…
