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 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…

VAR-PZnn: A machine-learning framework for AGN photometric redshifts using color and variability-based features

S. Satheesh-Sheeba, P. Sánchez-Sáez, R. J. Assef +39

Photometric redshift estimation for active galactic nuclei (AGNs) remains a fundamental challenge for current and upcoming large-scale photometric surveys. Traditional spectral ene…

Spatially resolved optical and mid-infrared spectroscopy of SDSS1335+0728: implications for the origin of the Ansky event

P. Sánchez-Sáez, M. Masterson, L. Hernández-García +25

The galaxy SDSS1335+0728 brightened abruptly in December 2019 (the Ansky event) and has since been confirmed as the host of extreme X-ray quasi-periodic eruptions (QPEs) of debated…

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…

Investigating Changing-Look Active Galactic Nuclei with Long-term Optical and X-Ray Observations

A. Jana, C. Ricci, M. J. Temple +7

Changing-look active galactic nuclei (CLAGNs) show the appearance and disappearance of broad emission lines in their UV/optical spectra on timescales of months to decades. Here, we…
