The hot interstellar medium towards 4U 1820-30: a Bayesian analysis
Daniele Rogantini, Elisa Costantini, Missagh Mehdipour +3
High ionisation lines in the soft X-ray band are generally associated to either interstellar hot gas along the line of sight or to photoionised gas intrinsic to the source. In the…
Compton-thick active galactic nuclei from the 7 Ms observation in the Chandra Deep Field South
A. Corral, I. Georgantopoulos, A. Akylas +1
We present the X-ray spectroscopic study of the Compton-thick (CT) active galactic nuclei (AGN) population within the Deep Field South (CDF-S) by using the deepe…
The XMM deep survey in the CDF-S. X. X-ray variability of bright sources
S. Falocco, M. Paolillo, A. Comastri +6
We aim to study the variability properties of bright hard X-ray selected Active Galactic Nuclei (AGN) with redshift between 0.3 and 1.6 detected in the Chandra Deep Field South (XM…
A New, Faint Population of X-ray Transients
F. E. Bauer, E. Treister, K. Schawinski +22
We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint ( mag, $z_{\rm ph}…
The 2-10 keV unabsorbed luminosity function of AGN from the XMM-Newton LSS, CDFS and COSMOS surveys
P. Ranalli, E. Koulouridis, I. Georgantopoulos +15
The XMM-LSS, XMM-COSMOS, and XMM-CDFS surveys are complementary in terms of sky coverage and depth. Together, they form a clean sample with the least possible variance in instrumen…
Searching for highly obscured AGN in the XMM-Newton serendipitous source catalog
A. Corral, I. Georgantopoulos, M. G. Watson +9
The majority of active galactic nuclei (AGN) are obscured by large amounts of absorbing material that makes them invisible at many wavelengths. X-rays, given their penetrating powe…
