project: III. Gas mass fraction shape in high redshift clusters
Rachida Sadat, Alain Blanchard, Sebastien C. Vauclair +10
We study the gas mass fraction, behavior in project. The typical shape of high redshift galaxy clusters follows the global shape inf…
The INTEGRAL view of the Soft Gamma-ray Repeater SGR 1806-20
D. Gotz, S. Mereghetti, I. F. Mirabel +21
We present the results obtained by INTEGRAL on the Soft-Gamma Ray Repeater SGR 1806-20. In particular we report on the temporal and spectral properties of the bursts detected durin…
GRB010921: Localization and Observations by the HETE Satellite
G. Ricker, K. Hurley, D. Lamb +36
On September 21 at 18950.56 SOD (05:15:50.56) UT the FREGATE gamma-ray instrument on the High Energy Transient Explorer (HETE) detected a bright gamma-ray burst (GRB). The burst wa…
Hands-On Universe: A Global Program for Education and Public Outreach in Astronomy
M. Boer, H. Pack, C. Pennypacker +3
Hands-On Universe (HOU) is an educational program that enables students to investigate the Universe while applying tools and concepts from science, math, and technology. Using the…
Hands-On TAROT: Intercontinental use of the TAROT for Education and Public Outreach
M. Boer, C. Thiebaut, A. Klotz +4
The TAROT telescope has for primary goal the search for the prompt optical counterpart of Cosmic Gamma-Ray Bursts. It is a completely autonomous 25cm telescope installed near Nice…
The XMM-Newton Project
J. G. Bartlett, N. Aghanim, M. Arnaud +16
The abundance of high-redshift galaxy clusters depends sensitively on the matter density $\OmM$ and, to a lesser extent, on the cosmological constant . Measurements of this abun…
