Rapid optical and X-ray timing observations of GX 339-4: multi-component optical variability in the low/hard state
P. Gandhi, V. S. Dhillon, M. Durant +9
A rapid timing analysis of VLT/ULTRACAM and RXTE observations of the black hole binary GX 339-4 in its 2007 low/hard state is presented. The optical light curves in the r', g' and…
Suzaku Discovery of a Hard X-Ray Tail in the Persistent Spectra from the Magnetar 1E 1547.0-5408 during its 2009 Activity
Enoto Teruaki, Nakazawa Kazuhiro, Makishima Kazuo +8
The fastest-rotating magnetar 1E 1547.0-5408 was observed in broad-band X-rays with Suzaku for 33 ks on 2009 January 28-29, 7 days after the onset of its latest bursting activity.…
Energy-Dependent Harmonic Ratios of the Cyclotron Features of X0331+53 in the 2004-2005 Outburst
Motoki. Nakajima, Tatehiro. Mihara, Kazuo. Makishima
We report on changes of the cyclotron resonance energies of the recurrent transient pulsar, X0331+53 (V0332+53). The whole RXTE data acquired in the 2004-2005 outburst were utilize…
