Chandra and HST Observations of Radio-Selected (Wandering) Massive Black Hole Candidates in Dwarf Galaxies
Megan R. Sturm, Amy E. Reines, Anne M. Lohfink +6
We present Chandra X-ray Observatory and Hubble Space Telescope (HST) follow-up observations of 12 dwarf galaxies from Reines et al. (2020) that are potential hosts of radio-select…

A New Approach to the Low Frequency Stochastic Gravitational Wave Background: Constraints from Quasars and the Astrometric Hellings-Downs Curve
Jeremy Darling
We present new astrometric constraints on the stochastic gravitational wave background and construct the first astrometric Hellings-Downs curve using quasar proper motions. From qu…

Dwarf Galaxies with Radio-excess AGNs in the VLA Sky Survey
John-Michael Eberhard, Amy E. Reines, Hansung B. Gim +2
We present a systematic search for radio active galactic nuclei (AGNs) in dwarf galaxies using recent observations taken by the Very Large Array Sky Survey (VLASS). To select these…
