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…

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…

A New Record Census of Dwarf AGN and a Bimodal - Scaling Relation with DESI DR1

Ragadeepika Pucha, S. Juneau, M. Mezcua +48

Using the first spectroscopic data release from the Dark Energy Spectroscopic Instrument (DESI DR1), we conduct the largest systematic search for active galactic nuclei (AGN) signa…

OzDES Reverberation Mapping Program: Stacking analysis with H, Mg II and C IV

Umang Malik, Rob Sharp, A. Penton +47

Reverberation mapping is the leading technique used to measure direct black hole masses outside of the local Universe. Additionally, reverberation measurements calibrate secondary…

OzDES Reverberation Mapping Program: H lags from the 6-year survey

Umang Malik, Rob Sharp, A. Penton +64

Reverberation mapping measurements have been used to constrain the relationship between the size of the broad-line region and luminosity of active galactic nuclei (AGN). This …

On Reverberation Mapping Lag Uncertainties

Zhefu Yu, C. S. Kochanek, B. M. Peterson +5

We broadly explore the effects of systematic errors on reverberation mapping lag uncertainty estimates from {\tt JAVELIN} and the interpolated cross-correlation function (ICCF) met…

Active Galaxy Science in the LSST Deep-Drilling Fields: Footprints, Cadence Requirements, and Total-Depth Requirements

W. N. Brandt, Q. Ni, G. Yang +25

This white paper specifies the footprints, cadence requirements, and total-depth requirements needed to allow the most-successful AGN studies in the four currently selected LSST De…

Quasar Accretion Disk Sizes from Continuum Reverberation Mapping in the DES Standard Star Fields

Zhefu Yu, Paul Martini, T. M. Davis +72

Measurements of the physical properties of accretion disks in active galactic nuclei are important for better understanding the growth and evolution of supermassive black holes. We…
