A search for X-ray absorbed sources in the 3XMM catalogue, using photometric redshifts and Bayesian spectral fits
A. Ruiz, I. Georgantopoulos, A. Corral
Since its launch in 1999, the XMM-\textit{Newton} mission has compiled the largest catalogue of serendipitous X-ray sources, with the 3XMM being the third version of this catalogue…
Compton Thick AGN in the 70 Month Swift-BAT All-Sky Hard X-ray Survey: a Bayesian approach
A. Akylas, I. Georgantopoulos, P. Ranalli +3
The 70-month Swift/BAT catalogue provides a sensitive view of the extragalactic X-ray sky at hard energies (>10 keV) containing about 800 Active Galactic Nuclei. We explore its con…
Exploring the Active Galactic Nuclei population with extreme X-ray to optical flux ratios (Fx/Fo >50)
R. Della Ceca, F. J. Carrera, A. Caccianiga +8
The cosmic history of the growth of supermassive black holes in galactic centers parallels that of star-formation in the Universe. However, an important fraction of this growth occ…
The XMM-Newton Bright Survey sample of absorbed quasars: X-ray and accretion properties
L. Ballo, P. Severgnini, R. Della Ceca +5
Although absorbed quasars are extremely important for our understanding of the energetics of the Universe, the main physical parameters of their central engines are still poorly kn…
Relativistic reflection in the average X-ray spectrum of AGN in the Véron-Cetty & Véron catalogue
S. Falocco, F. J. Carrera, X. Barcons +2
The X-ray spectra of active galactic nuclei (AGN) unveil properties of matter around the super massive black hole (SMBH). We investigate the X-ray spectra of AGN focusing on Compto…
The XMM-Newton spectral-fit database
A. Corral, I. Georgantopoulos, S. Rosen +3
The XMM-Newton spectral-fit database is an ongoing ESA funded project aimed to construct a catalogue of spectral-fitting results for all the sources within the XMM-Newton serendipi…
