Obscured and unobscured X-ray AGNs I: Host galaxy properties

Carlos G. Bornancini, Gabriel A. Oio, Georgina Coldwell

Active galactic nuclei (AGN) play a crucial role in galaxy evolution by influencing the observational properties of their host galaxies. We investigate the host galaxy properties o…

The role of bars in triggering active galactic nuclei galaxies

V. Marels, V. Mesa, M. Jaque Arancibia +4

Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies, potentially enhancing nuclear activity. However, the extent to which bars in…

High energy gamma-ray sources in the VVV survey -- II. The AGN counterparts

Laura G. Donoso, Ana Pichel, Laura D. Baravalle +9

We identified Active Galactic Nuclei (AGN) candidates as counterparts to unidentified gamma-ray sources (UGS) from the Fermi-LAT Fourth Source Catalogue at lower Galactic latitudes…
