The 2007 outburst of the X-ray binary XTE J1856+053
G. Sala, J. Greiner, M. Ajello +1
On 28 February 2007 a new outburst of the previously known transient source XTE J1856+053 was detected with RXTE/ASM. We present here the results of an XMM-Newton (0.5-10.0 keV) Ta…
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…
The 2175 A dust feature in a Gamma Ray Burst afterglow at redshift 2.45
T. Krühler, A. Küpcü Yoldaş, J. Greiner +6
We present optical and near-infrared photometry of the afterglow of the long Gamma-Ray Burst GRB 070802 at redshift 2.45 obtained with the ESO/MPI 2.2 m telescope equipped with the…
The complex light-curve of the afterglow of GRB071010A
S. Covino, P. D'Avanzo, A. Klotz +51
We present and discuss the results of an extensive observational campaign devoted to GRB071010A, a long-duration gamma-ray burst detected by the Swift satellite. This event was fol…
GROND - a 7-channel imager
J. Greiner, W. Bornemann, C. Clemens +19
We describe the construction of GROND, a 7-channel imager, primarily designed for rapid observations of gamma-ray burst afterglows. It allows simultaneous imaging in the Sloan g'r'…
