A note on Temperature Profiles of rich Clusters of Galaxies
Sabrina De Grandi, Silvano Molendi
We derive here the mean temperature profile for a sample of hot, medium distant clusters recently observed with XMM-Newton, whose profiles are available from the literature, and co…
The Intra-Cluster Medium
Silvano Molendi
The Intra-Cluster Medium (ICM) is a rarefied, hot, highly ionized, metal rich, weakly magnetized plasma. In these proceeding, after having reviewed some basic ICM properties, I dis…
Radiative cooling, heating and thermal conduction in M87
Simona Ghizzardi, Silvano Molendi, Fabio Pizzolato +1
The crisis of the standard cooling flow model brought about by Chandra and XMM-Newton observations of galaxy clusters, has led to the development of several models which explore di…
The HELLAS2XMM survey: VI. X-ray absorption in the 1dfAGN sample through a spectral analysis
G. C. Perola, S. Puccetti, F. Fiore +13
The spectroscopic analysis of 117 serendipitous sources in the HELLAS2XMM 1df (1 degree field) survey is described. Of these, 106 sources, of which 86% have a spectroscopic redshif…
The EPIC/MOS view of the 2-8 keV Cosmic X-ray Background Spectrum
A. De Luca, S. Molendi
We have measured the spectrum of the Cosmic X-ray Background (CXB) in the 2-8 keV range with the high throughput EPIC/MOS instrument onboard XMM-Newton. A large sample of high gala…
The HELLAS2XMM survey. V. Near-Infrared observations of X-ray sources with extreme X/O ratios
M. Mignoli, L. Pozzetti, A. Comastri +12
We present the results of deep near-infrared observations of 11 hard X-ray selected sources in the Hellas2XMM survey, with faint optical magnitude (R>24) and high X-ray-to-optical…
