A photometric redshift of for the \agile GRB 080514B
A. Rossi, A. de Ugarte Postigo, P. Ferrero +26
Aims: The AGILE gamma-ray burst GRB 080514B is the first burst with detected emission above 30 MeV and an optical afterglow. However, no spectroscopic redshift for this burst is kn…
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…
XMM-Newton observation of the Lockman Hole II. Spectral analysis
V. Mainieri, J. Bergeron, G. Hasinger +5
We present the results of the X-ray spectral analysis of the first deep X-ray survey with the XMM-Newton observatory during Performance Verification. We restrict the analysis to th…
Galaxy Number Counts from the Sloan Digital Sky Survey Commissioning Data
Naoki Yasuda, Masataka Fukugita, Vijay K. Narayanan +10
We present bright galaxy number counts in five broad bands () from imaging data taken during the commissioning phase of the Sloan Digital Sky Survey (SDSS). The…
New Results from the X-ray and Optical Survey of the Chandra Deep Field South: The 300ks Exposure
P. Tozzi, P. Rosati, M. Nonino +15
We present results from 300 ks of X-ray observations of the Chandra Deep Field South. The field of the four combined exposures is now 0.1035 deg^2 and we reach a flux limit of 10^{…
