The density of very massive evolved galaxies to z~1.7
P. Saracco, M. Longhetti, P. Severgnini +8
We spectroscopically identified 7 massive evolved galaxies with magnitudes 17.8<K<18.4 at 1.3<z<1.7 over an area of ~160 arcmin^2 of the MUNICS survey. Their rest-frame K-band abso…
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…
Looking for obscured QSOs in the X-ray emitting ERO population
P. Severgnini, R. Della Ceca, V. Braito +8
We present XMM-Newton data centered on one of the MUNICS Near Infrared Cluster Survey fields (S2F1) and we discuss the X-ray properties of the 6 X-ray emitting EROs found. For one…
XMM-Newton spectroscopy of an X-ray selected sample of RL AGNs
E. Galbiati, A. Caccianiga, T. Maccacaro +6
This paper presents the X-ray spectroscopy of an X-ray selected sample of 25 radio-loud (RL) AGNs extracted from the XBSS sample. The main goal is to study the origin of the X-ray…
First XMM-Newton study of two Narrow-Line Seyfert 1 galaxies discovered in the Sloan Digital Sky Survey
L. Foschini, V. Braito, G. G. C. Palumbo +6
The Early Data Release of the Sloan Digital Sky Survey (SDSS) contains 150 Narrow-Line Seyfert 1 (NLS1) galaxies, most of them previously unknown. We present here the study of the…
Exploring the X-ray Sky with the XMM-Newton Bright Serendipitous Survey
R. Della Ceca, T. Maccacaro, A. Caccianiga +11
ABRIDGED. We present "The XMM-Newton Bright Serendipitous Survey", two flux-limited samples with flux limit fx ~7E-14 cgs in the 0.5-4.5 keV (BSS) and 4.5-7.5 keV (HBSS) energy ban…
The broad-band properties of the XMM-Newton Bright Serendipitous Sources
R. Della Ceca, T. Maccacaro, A. Caccianiga +2
We present here "The XMM-Newton Bright Serendipitous Survey", a survey program conducted by the XMM-Newton Survey Science Center. In particular we discuss the main goals of this pr…
2-10 keV luminosity of high-mass binaries as a gauge of ongoing star-formation rate
M. Persic, Y. Rephaeli, V. Braito +4
Based on recent work on spectral decomposition of the emission of star-forming galaxies, we assess whether the integrated 2-10 keV emission from high-mass X-ray binaries (HMXBs), L…
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…
An X-ray review of MS1054-0321: hot or not?
I. M. Gioia, V. Braito, M. Branchesi +4
XMM-Newton observations are presented for the z=0.83 cluster of galaxies MS1054-0321, the highest redshift cluster in the Einstein Extended Medium Sensitivity Survey (EMSS). The te…
