The XMM-Newton spectrum of the high-z optically-obscured QSO RX J1343.4+0001: a classic radio quiet QSO

E. Piconcelli, M. Guainazzi, M. Cappi +2

We present a 30 ks XMM-Newton observation of the z = 2.35 Type II radio quiet quasar RX J1343.4+0001. These data provide the first good quality X-ray spectrum for this object. We m…

Multi-wavelength study of a sample of nearby Seyfert galaxies

F. Panessa, L. Bassani, M. Cappi +2

One of the least biased complete Seyfert sample available to date has been considered to perform an X-ray survey using the capabilities of XMM-Newton and Chandra satellites. The X-…

Chandra observations of X-ray source overdensities in distant galaxy cluster fields

N. Cappelluti, M. Cappi, M. Dadina +4

The first systematic study of the serendipitous X-ray source density around 10 high z (0.24<z<1.2) clusters performed with Chandra is presented. A factor \~2 overdensity has been f…

X-ray properties of the "Composite" Seyfert/Star-forming galaxies

A. Wolter, G. Trinchieri, R. Della Ceca +7

An enigmatic, small class of IR and X-ray luminous sources, named ``Composite'' starburst/Seyfert galaxies, has been defined from IRAS and RASS data. The objects have optical spect…

The composite starburst/AGN nature of the superwind galaxy NGC 4666

M. Persic, M. Cappi, Y. Rephaeli +6

We report the discovery of a Compton-thick AGN and of intense star-formation activity in the nucleus and disk, respectively, of the nearly edge-on superwind galaxy NGC 4666. Spatia…

The Faint X-ray Source Population Near the 3C 295 cluster

V. D'Elia, F. Fiore, M. Elvis +5

We present a statistical analysis of the Chandra observation of the source field around the 3C 295 galaxy cluster (z=0.46). Three different methods of analysis, namely a chip by ch…
