UNCOVER Spectroscopy Confirms the Surprising Ubiquity of Active Galactic Nuclei in Red Sources at z > 5

open access: yesThe Astrophysical Journal
The James Webb Space Telescope is revealing a new population of dust-reddened broad-line active galactic nuclei (AGN) at redshifts z ≳ 5. Here we present deep NIRSpec/Prism spectroscopy from the Cycle 1 Treasury program Ultradeep NIRSpec and NIRCam ...

Unlocking AGN variability with custom ZTF photometry for high-fidelity light curves and robust selection

open access: yesAstronomy & Astrophysics
Aims. We explored the potential of optical variability selection methods in order to identify a broad range of active galactic nuclei (AGN), including those challenging to detect with conventional techniques. Using the unprecedented combination of depth,
