We present the results of a systematic analysis of the XMM-Newton spectra of nearby optically bright QSOs. The objects have been selected from X-ray Galaxy Catalog Xgal20. It is a catalog of 1172 manually identified and classified galaxies, obtained as a cross-correlation between the 4XMM-DR9 catalog and the Hyper-Linked Extragalactic Databases and Archives (HyperLeda) with an X-ray flux greater than F ≥ 10−13 erg/(cm2 · s). The goal of this work is to characterize the X-ray spectral properties…

X-ray absorption in distant type II QSOs ,
The results of the X-ray spectral analysis of an XMM-Newton-selected type II QSO sample with z≥ 0.5 and 0.510 keV flux are presented and it is determined that fitting the spectra with the Cash- statistic and a binning of minimum one count per bin recovers the input values of the simulated X-rays best.
Soft X-ray properties of a high-redshift sample of QSOs observed with ROSAT
In order to study systematically the soft X-ray emission of active galactic nuclei (AGNs) at medium to high redshifts, we have analysed ROSAT PSPC and HRI data of QSOs at 0.26 ≤ z ≤ 3.43 selected
The Chandra Deep Field-South: Optical Spectroscopy. I.*
We present the results of our spectroscopic follow-up program of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field-South (CDFS). A total of 288 possible counterparts were
XMM-Newton observation of the Lockman Hole - II. Spectral analysis
We present the results of the X-ray spectral analysis of the first deep X-ray survey with the XMM-Newton observa- tory during Performance Verification. The X-ray data of the Lockman Hole field and
The XMM-Newton view of PG quasars - I. X-ray continuum and absorption
We present results of a systematic analysis of the XMM-Newton spectra of 40 quasars (QSOs) (z ≤ 1.72) from the Palomar-Green (PG) Bright Quasar Survey sample (MB < −23). The sample includes 35
Optical Identification of the ASCA Large Sky Survey
We present results of optical identification of the X-ray sources detected in the ASCA Large Sky Survey. Optical spectroscopic observations were done for 34 X-ray sources which were detected with the
X-ray spectral properties of active galactic nuclei in the Chandra deep field south
We present a detailed X-ray spectral analysis of the sources in the 1Ms catalog of the Chandra Deep Field South (CDFS) taking advantage of optical spectroscopy and photometric redshifts for 321
The HELLAS2XMM Survey. II. Multiwavelength Observations of P3: An X-Ray-bright, Optically Inactive Galaxy*
Recent X-ray surveys have clearly demonstrated that a population of optically dull, X-ray–bright galaxies is emerging at 2–10 keV fluxes of the order of 10 � 14 ergs cm � 2 s � 1 . Although they
The Soft X-Ray Spectral Shape of X-Ray--weak Seyfert Galaxies
We present and analyze ROSAT PSPC observations of eight Seyfert 2 galaxies, two Seyfert 1/QSOs, and one IR-luminous non-Seyfert galaxy. These targets were selected from the Extended 12 μm Galaxy
A classic type 2 QSO
In the Chandra Deep Field-South 1 Ms exposure, we have found, at redshift 3.700 ± 0.005, the most distant type 2 active galactic nucleus ever detected. It is the source with the hardest X-ray
