A new activity phase of the blazar 3C 454.3. Multifrequency observations by the WEBT and XMM-Newton in 2007-2008
C. M. Raiteri, M. Villata, V. M. Larionov +2
We present and analyse the WEBT multifrequency observations of 3C 454.3 in the 2007-2008 observing season, including XMM-Newton observations and near-IR spectroscopic monitoring, a…
Evolution of AQL X-1 During the Rising Phase of its 1998 Outburst
Wei Cui, Didier Barret, S. N. Zhang +3
We present results from 16 snapshots of Aql X-1 with RXTE during the rising phase of its recent outburst. The observations were carried out at a typical rate of once or twice per d…
Evidence for Frame-Dragging Around Spinning Black Holes in X-Ray Binaries
Wei Cui, S. N. Zhang, Wan Chen
In the context of black hole spin in X-ray binaries, we propose that certain type of quasi-period oscillations (QPOs) observed in the light curves of black hole binaries (BHBs) are…
Black Hole Spin in X-Ray Binaries: Observational Consequences
S. N. Zhang, Wei Cui, Wan Chen
We discuss the observational consequences of black hole spin in X-ray binaries within the framework of the standard thin accretion disk model. When compared to theoretical flux dis…
Kilohertz QPO Peak Separation Is Not Constant in Scorpius X-1
Michiel van der Klis, Rudy A. D. Wijnands, Keith Horne +1
We report on a series of twenty ~10^5 c/s, 0.125 msec time-resolution RXTE observations of the Z source and low-mass X-ray binary Scorpius X-1. Twin kilohertz quasi-periodic oscill…
