We have performed a uniform analysis of the power spectrum densities (PSDs) of 104 nearby (z ~= 2 × 10-4 Hz. Only KUG 1031+398 (RE J1034+396) shows evidence for...
X-ray variability of 104 active galactic nuclei. XMM-Newton power-spectrum density profiles
Context. Active galactic nuclei (AGN), powered by accretion onto supermassive black holes (SMBHs), are thought to be scaled up versions of Galactic black hole X...
XMM-Newton detection of Nova Muscae 1991 in quiescence
The soft X-ray transient GU Mus has been detected by XMM-Newton in the quiescent state. The source is very faint, with a 0.5-10.0 keV unabsorbed flux of =~ 1.1...
