XMM-Newton observations of the Lockman Hole: X-ray source catalogue and number counts
H. Brunner, N. Cappelluti, G. Hasinger +4
The Lockman Hole field represents the sky area of lowest Galactic line-of-sight column density N_H=5.7X10^19 cm^-2. It was observed by the XMM-Newton X-ray observatory in 18 pointi…
NGC3147: a "true" Seyfert 2 without the broad-line region
S. Bianchi, A. Corral, F. Panessa +5
We report on simultaneous optical and X-ray observations of the Seyfert galaxy, NGC3147. The XMM-Newton spectrum shows that the source is unabsorbed in the X-rays ($N_H<5\times10^{…
The XMM-Newton bright serendipitous survey. Identification and optical spectral properties
A. Caccianiga, P. Severgnini, R. Della Ceca +12
AIMS: We present the optical classification and redshift of 348 X-ray selected sources from the XMM-Newton Bright Serendipitous Survey (XBS) which contains a total of 400 objects (…
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…
XMM-Newton observations of the Lockman Hole V: time variability of the brightest AGN
S. Mateos, X. Barcons, F. J. Carrera +4
This paper presents the results of a study of X-ray spectral and flux variability on time scales from months to years, of the 123 brightest objects (including 46 type-1 AGN and 28…
The XMM-Newton serendipitous survey IV. The AXIS X-ray source counts and angular clustering
F. J. Carrera, J. Ebrero, S. Mateos +14
AXIS (An XMM-Newton International Survey) is a survey of 36 high Galactic latitude XMM-Newton observations covering 4.8 deg2 and containing 1433 serendipitous X-ray sources detecte…
