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…
A Test of the Cosmological Principle with Quasars
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +3
We study the large-scale anisotropy of the Universe by measuring the dipole in the angular distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wi…
Detection of a Radio Bubble around the Ultraluminous X-ray Source Holmberg IX X-1
Ciprian T. Berghea, Megan C. Johnson, Nathan J. Secrest +3
We present C and X-band radio observations of the famous utraluminous X-ray source (ULX) Holmberg IX X-1, previously discovered to be associated with an optical emission line nebul…
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…
