The XMM-Newton Serendipitous Survey. V. The Second XMM-Newton Serendipitous Source Catalogue
M. G. Watson, A. C. Schröder, D. Fyfe +47
Aims: Pointed observations with XMM-Newton provide the basis for creating catalogues of X-ray sources detected serendipitously in each field. This paper describes the creation and…
The XMM-Newton Serendipitous Survey V. Optical identification of the XMM-Newton Medium sensitivity Survey (XMS)
X. Barcons, F. J. Carrera, M. T. Ceballos +53
We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comp…
3-5 micron spectroscopy of obscured AGNs in ULIRGs
E. Sani, G. Risaliti, M. Salvati +6
We present the results of infrared L-band (3-4 micron) and M-band (4-5 micron) VLT-ISAAC spectroscopy of five bright Ultraluminous InfraRed Galaxies (ULIRGs) hosting an AGN. From o…
An X-ray bright ERO hosting a type 2 QSO
P. Severgnini, A. Caccianiga, V. Braito +8
We present the XMM-Newton and the optical-VLT spectra along with the optical and the near-infrared photometric data of one of the brightest X-ray (F(2-10 keV)~1e-13 erg/s cm^2) ext…
The double AGN in NGC 6240 revealed through 3-5 micron spectroscopy
G. Risaliti, E. Sani, R. Maiolino +7
We present 3-5 micron spectroscopy of the interacting system NGC 6240, showing the presence of two active galactic nuclei. The brightest (southern) nucleus shows up with a starburs…
X-ray Line Emitting Objects in XMM-Newton Observations: the Tip of the Iceberg
T. Maccacaro, V. Braito, R. Della Ceca +2
We present preliminary results from a novel search for X-ray Line Emitting Objects (XLEOs) in XMM-Newton images. Three sources have been detected in a test-run analysis of 13 XMM-N…
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 XMM-Newton and BeppoSAX view of the Ultra Luminous Infrared Galaxy MKN 231
V. Braito, R. Della Ceca, E. Piconcelli +11
We discuss XMM-Newton and BeppoSAX observations of MKN 231, the lowest-redshift Broad Absorption Line (BAL) QSO known so far and one of the best-studied Ultra Luminous Infrared Gal…
Chandra and XMM-Newton Observations of RDCS1252.9-2927, A Massive Cluster at z=1.24
P. Rosati, P. Tozzi, S. Ettori +10
We present deep Chandra and XMM obervations of the galaxy cluster RDCS1252.9-2927, which was selected from the ROSAT Deep Cluster Survey (RDCS) and confirmed by extensive spectrosc…
Revealing the active galactic nucleus in the superantennae through L-band spectroscopy
G. Risaliti, R. Maiolino, A. Marconi +6
We present an L-band spectrum of the Ultraluminous Infrared Galaxy IRAS 19254-7245 (the Superantennae), obtained with VLT-ISAAC. The high signal to noise ratio allows a study of th…
Arp 299: a second merging system with two active nuclei?
L. Ballo, V. Braito, R. Della Ceca +3
Recent BeppoSAX observations of Arp 299, a powerful far-IR merging starburst system composed of IC 694 and NGC 3690, clearly unveiled for the first time in this system the presence…
An XMM-Newton Survey of Ultra-Luminous Infrared Galaxies
V. Braito, A. Franceschini, R. Della Ceca +8
We present preliminary results of XMM-Newton observations of 5 Ultra-luminous Infrared Galaxies (ULIRGs), part of a mini-survey program dedicated to 10 ULIRGs selected from the bri…
First Results from a XMM-Newton Survey of a Distance-Limited (D<22 Mpc) Sample of Seyfert Galaxies: I- the Agns
M. Cappi, G. Di Cocco, F. Panessa +18
We report here preliminary results from a survey of nearby Seyfert galaxies using the EPIC CCDs on board XMM-Newton. The total sample consists of 28 Seyfert galaxies, and constitut…
X-ray detections of weak Seyfert2's with BeppoSAX
M. Salvati, L. Bassani, R. Della Ceca +3
We report the detection in the X rays of two weak Seyfert2's (NGC3393 and NGC4941) with the Italian-Dutch satellite BeppoSAX. These are among the first sources observed in a sample…
