Fundamental Reference AGN Monitoring Experiment (FRAMEx) I: Jumping Out of the Plane with the VLBA

Travis C. Fischer, Nathan J. Secrest, Megan C. Johnson +7

We present the first results from the Fundamental Reference AGN Monitoring Experiment (FRAMEx), an observational campaign dedicated to understanding the physical processes that aff…

The Diagnostic Potential of JWST in Characterizing Elusive AGNs

Shobita Satyapal, Lara Kamal, Jenna M. Cann +2

It is now clear that a significant population of accreting black holes are undetected by commonly employed optical, mid-infrared color, X-ray, and radio selection methods due to ob…

The X-ray View of Merger-Induced AGN Activity at Low Redshift

Nathan Secrest, Sara Ellison, Shobita Satyapal +1

Galaxy mergers are predicted to trigger accretion onto the central supermassive black holes, with the highest rates occurring during final coalescence. Previously, we have shown el…

A Low Incidence of Mid-Infrared Variability in Dwarf Galaxies

Nathan Secrest, Shobita Satyapal

Using 8.4 years of photometry from the AllWISE/NEOWISE multi-epoch catalogs, we compare the mid-infrared variability properties of a sample of 2197 dwarf galaxies (M_stellar < 2 x…

Multi-wavelength observations of SDSS J105621.45+313822.1, a broad-line, low-metallicity AGN

Jenna M. Cann, Shobita Satyapal, Thomas Bohn +8

In contrast to massive galaxies with Solar or super-Solar gas phase metallicities, very few Active Galactic Nuclei (AGN) are found in low-metallicity dwarf galaxies. Such a populat…
