Constraining the cosmological parameters with the gas mass fraction in local and z>0.7 Galaxy Clusters
S. Ettori, P. Tozzi, P. Rosati
We present a study of the baryonic fraction in galaxy clusters aimed at constraining the cosmological parameters Omega_m, Omega_Lambda and the ratio between the pressure and densit…
The Evolution of X-ray Clusters of Galaxies
Piero Rosati, Stefano Borgani, Colin Norman
Considerable progress has been made over the last decade in the study of the evolutionary trends of the population of galaxy clusters in the Universe. In this review we focus on ob…
SPICES II. Optical and Near-Infrared Identifications of Faint X-Ray Sources from Deep Chandra Observations of Lynx
Daniel Stern, Paolo Tozzi, S. A. Stanford +10
We present our first results on field X-ray sources detected in a deep, 184.7 ks observation with the ACIS-I camera on Chandra. The observations target the Lynx field of SPICES, an…
Moderate Temperature Clusters of Galaxies from the RDCS and the High Redshift Luminosity-Temperature Relation
B. P. Holden, S. A. Stanford, G. K. Squires +4
We present our discovery observations and analysis of RDCS1317+2911, z = 0.805, and RDCS1350+6007, z= 0.804, two clusters of galaxies identified through X-ray emission in the ROSAT…
XMM-Newton observations of the Lockman Hole : Spectral analysis
V. Mainieri, J. Bergeron, P. Rosati +2
We present the results of the X-ray spectral analysis of the deep survey obtained with the XMM-Newton observatory on the Lockman Hole. The X-ray data and the cumulative source coun…
