The Role of Environment in Triggering Active Galactic Nuclei—Evidence for a Change at z ∼ 1

The Astrophysical Journal
What triggers active galactic nuclei (AGN) in some galaxies and what role this brief period of activity plays in the overall evolution of galaxies are still open questions. This paper explores whether or not the local, on scales of ≈1 Mpc, galaxy density

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

Astronomy & 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,

Revised Active Galactic Nuclei Spectral Model Reveals a More Significant Role in Cosmic Reionization

The Astrophysical Journal Letters
Reionization marks one of the most important phase transitions in the history of the Universe, during which neutral baryonic matter was transformed into ionized plasma.

Lyman Continuum Emission from Active Galactic Nuclei at 2.3 ≲ z ≲ 3.7 in the UVCANDELS Fields

The Astrophysical Journal
We present the results of our search for Lyman continuum (LyC)-emitting (weak) active galactic nuclei (AGN) at redshifts 2.3 ≲ z ≲ 4.9 from Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) F275W observations in the Ultraviolet Imaging of the ...
