The Compton-thick AGN luminosity function in the local Universe: A robust estimate combining BAT detections and NuSTAR spectra
I. Georgantopoulos, E. Pouliasis, A. Ruiz +1
The Compton-thick Active Galactic Nuclei (AGN) arguably constitute the most elusive class of sources as they are absorbed by large column densities above logN_H(cm^-2)=24. These ex…
AGN populations in the local universe: their alignment with the main-sequence, characteristics of their stellar populations, accretion efficiency, and the impact of AGN feedback
G. Mountrichas, A. Ruiz, I. Georgantopoulos +3
In this study, we utilize a sample of 338 galaxies within the redshift range of , drawn from the Sloan Digital Sky Survey (SDSS), for which there are available clas…
Observational Properties of AGN Obscuration During the Peak of Accretion Growth
Bovornpratch Vijarnwannaluk, Masayuki Akiyama, Malte Schramm +11
We investigated the gas obscuration and host galaxy properties of active galactic nuclei (AGN) during the peak of cosmic accretion growth of supermassive black holes (SMBHs) at red…
AGN X-ray luminosity function and absorption function in the Early Universe ()
E. Pouliasis, A. Ruiz, I. Georgantopoulos +15
The XLF of AGN offers a robust tool to study the evolution and the growth of SMBHs over cosmic time. Owing to the limited area probed by X-ray surveys, optical surveys are routinel…
