A strong optical flare before the rising afterglow of GRB 080129
J. Greiner, T. Krühler, S. McBreen +11
We report on GROND observations of a 40 sec duration (rest-frame) optical flare from GRB 080129 at redshift 4.349. The rise- and decay time follow a power law with indices +12 and…
Three X-ray transients in M31 observed with Swift
R. Voss, W. Pietsch, F. Haberl +5
The purpose of this study is to find transient X-ray sources in M31, and to investigate and classify their nature. Three X-ray transients were observed with Swift. For each of the…
Looking for black-holes in X-ray binaries with XMM-Newton: XTE J1817-330 and XTE J1856+053
Gloria Sala, Jochen Greiner, Natalia Primak
The X-ray binary XTE J1817-330 was discovered in outburst on 26 January 2006 with RXTE/ASM. One year later, another X-ray transient discovered in 1996, XTE J1856+053, was detected…
V5116 Sgr, an Eclipsing Supersoft Post-Outburst Nova?
Gloria Sala, Margarita Hernanz, Carlo Ferri +1
V5116 Sgr (Nova Sgr 2005 No. 2), discovered on 2005 July 4, was observed with XMM-Newton in March 2007, 20 months after the optical outburst. The X-ray spectrum shows that the nova…
