The link among X-ray spectral properties, AGN structure and the host galaxy
G. Mountrichas, A. Viitanen, F. J. Carrera +5
In this work, we compare the SMBH and host galaxy properties of X-ray obscured and unobscured AGN. For that purpose, we use X-ray detected AGN in the 4XMM-DR11 catalo…
The properties of supermassive black holes and their host galaxies for type 1 and 2 AGN in the eFEDS and COSMOS fields
G. Mountrichas, I. Georgantopoulos
In this study, our primary objective is to compare the properties of SMBH and their host galaxies between type 1 and type 2 AGN. In our analysis, we use X-ray detected sources in t…
The STATiX pipeline for the detection of X-ray transients in three dimensions
A. Ruiz, A. Georgakakis, I. Georgantopoulos +3
The recent serendipitous discovery of a new population of short duration X-ray transients, thought to be associated with collisions of compact objects or stellar explosions in dist…
XMM2ATHENA, the H2020 project to improve XMM-Newton analysis software and prepare for Athena
Natalie A. Webb, Francisco J. Carrera, Axel Schwope +31
XMM-Newton, a European Space Agency observatory, has been observing the X-ray, ultra-violet and optical sky for 23 years. During this time, astronomy has evolved from mainly studyi…
Comparing the host galaxy ages of X-ray selected AGN in COSMOS: Obscured AGN are associated with older galaxies
I. Georgantopoulos, E. Pouliasis, G. Mountrichas +3
We explore the properties of the host galaxies of X-ray selected AGN in the COSMOS field using the Chandra Legacy sample and the LEGA-C survey VLT optical spectra. Our main goal is…
Star-forming early- and quiescent late-type galaxies in the local Universe
E. -D. Paspaliaris, E. M. Xilouris, A. Nersesian +5
The general consensus is that LTGs undergo intense star-formation activity, while ETGs are mostly inactive. We question this general rule and investigate the existence of star-form…
