Radio Active Galactic Nuclei Activity in Low Redshift Galaxies Is Not Directly Related to Star Formation Rates

open access: yesThe Astrophysical Journal
We examine the demographics of radio-emitting active galactic nuclei (AGN) in the local Universe as a function of host galaxy properties, most notably both stellar mass ( M _⋆ ) and star formation rate (SFR).

Calibrating the DMIGM–z Relation Using Host Galaxy Properties of Fast Radio Bursts

open access: yesThe Astrophysical Journal
Fast radio bursts (FRBs) are extragalactic radio transients that offer valuable insight into the intergalactic medium (IGM). However, the dispersion measure (DM) contributed by the IGM (DM _IGM ) is degenerate with that from the host galaxy (DM _host ...

Hubble Space Telescope Observations within the Sphere of Influence of the Powerful Supermassive Black Hole in PKS 0745-191

open access: yesThe Astrophysical Journal
We present Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope of the supermassive black hole (SMBH) at the center of PKS 0745-191, a brightest cluster galaxy (BCG) undergoing powerful radio-mode active galactic nucleus (AGN)

A Catalog of Local Universe Fast Radio Bursts from CHIME/FRB and the KKO

open access: yesThe Astrophysical Journal Supplement Series
We present the first catalog of fast radio burst (FRB) host galaxies from CHIME/FRB Outriggers, selected uniformly in the radio and the optical by localizing 81 new bursts to 2″ × ∼ 60″ accuracy using CHIME and the k’niʔatn k’l ⌣ stk’masqt Outrigger ...
