On the Iron content in rich nearby Clusters of Galaxies
Sabrina De Grandi, Stefano Ettori, Marcella Longhetti +1
In this paper we study the iron content of a sample of 22 nearby hot clusters observed with BeppoSAX. We find that the global iron mass of clusters is tightly related to the cluste…
The high energy emission line spectrum of NGC 1068
Giorgio Matt, Stefano Bianchi, Matteo Guainazzi +1
We present and discuss the high energy (E>4 keV) XMM-Newton spectrum of the Seyfert 2 galaxy, NGC 1068. Possible evidence for flux variability in both the neutral and ionized refle…
The HELLAS2XMM 1dF survey: on the nature of high X-ray to optical flux ratio sources
F. Fiore, M. Brusa, F. Cocchia +12
We present results from the photometric and spectroscopic identification of 122 X-ray sources discovered by XMM-Newton in the 2-10 keV band (the HELLAS2XMM 1dF sample). One of the…
The XMM-Newton hard band wide angle Survey
N. Carangelo, S. Molendi, the Hellas2XMM collaboration
We present the preliminary findings of our XMM-Newton Survey performed in the hard band [7-11] keV. The survey covers nearly 30 squares degrees for a total of 112 fields observed.…
Ni abundance in the core of the Perseus Cluster: an answer to the significance of resonant scattering
Fabio Gastaldello, Silvano Molendi
Using an XMM-Newton observation of the Perseus cluster we show that the excess in the flux of the 7-8 keV line complex previously detected by ASCA and BeppoSAX is due to an overabu…
The Hellas2XMM survey: III. Multiwavelength observations of hard X-ray selected sources in the PKS 0312-77 field
M. Brusa, A. Comastri, M. Mignoli +11
We present extensive optical, radio and infrared follow-up observations of a sample of 35 hard X-ray (2-10 keV) selected sources discovered serendipitously in the PV XMM-Newton obs…
