Photometric redshifts for active galactic nuclei with LePHARE for the Vera C. Rubin Observatory

R. Shirley, M. Salvato, J. Cohen-Tanugi +31

Active Galactic Nuclei (AGN) play a crucial role in galaxy evolution, but they are a minority of extragalactic sources with diverse Spectral Energy Distributions (SEDs), which depe…

The incidence of eROSITA X-ray AGN in the local Universe: from dwarf to massive galaxies

Z. Igo, A. Merloni, A. Georgakakis +22

Combining deep, wide-area X-ray surveys with multi-wavelength catalogues provides insights into rare, highly-accreting AGN and low-mass galaxies at low redshift, the latter potenti…

The eROSITA X-ray luminosity function of active galactic nuclei

W. Roster, J. Buchner, M. Salvato +23

The X-ray luminosity function (XLF) of active galactic nuclei (AGN) provides an observational probe of the growth of supermassive black holes (SMBHs) across cosmic time. With its l…

The X-ray-Weak Tail of the Quasar Population: Physical Properties and Redshift Evolution of Variability-Selected AGN in eFEDS

P. Arévalo, J. Buchner, M. Salvato +10

(abridged) Aims: To characterize variability-selected AGN candidates within the eROSITA Final Equatorial-Depth Survey (eFEDS), leveraging the synergy between optical variability an…

Robust AGN and host-galaxy decomposition in optical spectral fitting

C. Aydar, A. Merloni, G. Zeltyn +24

Unraveling the growth of supermassive black holes and their connection to host galaxies requires disentangling the Active Galactic Nuclei (AGN) emission from that of the stellar po…

SDSS-V Black Hole Mapper: The Index Diagram as a tool to disentangle the influence of the Host Galaxy in Quasar spectra

C. A. Negrete, R. Sandoval-Orozco, H. Ibarra-Medel +32

We revisit the Quasar Main Sequence (QMS) by investigating the impact of the stellar component from the host galaxy (HG) on the emission line spectra of the active galactic nuclei…
