Modeling Star Formation Histories of Changing-look AGN Host Galaxies with Prospector

The Astrophysical Journal
Changing-look active galactic nuclei (CL-AGNs), are AGNs that appear to transition between Seyfert Type 1 and 2 over periods of months to years. Several mechanisms to trigger these transitions have been proposed, but we have yet to conclusively determine

The Perpendicularity of Dust Lanes and Radio Jets in Early-type Galaxies: Implications for Active Galactic Nuclei Feedback

The Astrophysical Journal
The orientation of radio jets relative to their host galaxies offers an interesting avenue for probing the connection between active galactic nuclei (AGN) and their surroundings.

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,

ALMA/SCUBA-2 COSMOS Survey: Properties of X-Ray- and SED-selected Active Galactic Nuclei in Bright Submillimeter Galaxies

The Astrophysical Journal
We investigate the properties of active galactic nuclei (AGNs) in the brightest submillimeter galaxies (SMGs) in the COSMOS field. We utilize the bright sample of the ALMA/SCUBA-2 COSMOS Survey (AS2COSMOS), which consists of 260 SMGs with S _870 _μ _m  =
