Chandra Observations of Six QSOs at z 3
Takamitsu Miyaji, Guenther Hasinger, Ingo Lehmann +1
We report the results of our Chandra observations of six QSOs at from the Palomer Transit Grism Survey. Our primary goal is to investigate the possible systematic change…
XMM-Newton view of the ultra-luminous X-ray sources in M51
Gulab C. Dewangan, Richard E. Griffiths, Manojendu Choudhury +2
(Abridged) We present results based on XMM-Newton observation of the nearby spiral galaxy M51 (NGC5194 and NGC5195). Two ULXs in NGC5194 show evidence for short-term variability, a…
The Extended Chandra Deep Field-South Survey. Chandra Point-Source Catalogs
B. D. Lehmer, W. N. Brandt, D. M. Alexander +17
We present Chandra point-source catalogs for the Extended Chandra Deep Field-South (E-CDF-S) survey. The E-CDF-S consists of four contiguous 250 ks Chandra observations covering an…
Luminosity-dependent evolution of soft X-ray selected AGN: New Chandra and XMM-Newton surveys
G. Hasinger, T. Miyaji, M. Schmidt
We present new results on the cosmological evolution of unabsorbed (type-1) active galactic nuclei (AGN) selected in the soft (0.5-2 keV) X-ray band. From a variety of ROSAT, XMM-N…
