A Radio Study of Persistent Radio Sources in Nearby Dwarf Galaxies: Implications for Fast Radio Bursts

The Astrophysical Journal
We present 1–12 GHz Karl G. Jansky Very Large Array observations of nine off-nuclear persistent radio sources (PRSs) in nearby ( z ≲ 0.055) dwarf galaxies, along with high-resolution European VLBI Network observations for one of them at 1.7 GHz.

Kinematics of Extragalactic Radio Sources

, 2004
Symmetric extragalactic radio sources exhibit a baffling array of features - the remarkable symmetry between the two lobes, the emission in the radio frequency range, well collimated jets, core regions emitting blue and ultraviolet light, transient X-ray and gamma ray bursts, etc.

An Image-based Search for Pulsar Candidates in the MeerKAT Bulge Survey

The Astrophysical Journal
We report on the results of an image-based search for pulsar candidates toward the Galactic bulge. We used mosaic images from the MeerKAT radio telescope that were taken as part of a 173 deg ^2 survey of the bulge and Galactic center of our Galaxy at L ...

New Constraints on the Evolution of the MH i−M⋆ Scaling Relation Combining CHILES and MIGHTEE-H i Data

The Astrophysical Journal
The improved sensitivity of interferometric facilities to the 21 cm line of atomic hydrogen (H i ) enables studies of its properties in galaxies beyond the local Universe.

FAST Survey of H i and OH Absorption toward Extragalactic Radio Sources

The Astrophysical Journal
Neutral atomic hydrogen and molecular gas in the host galaxies of radio active galactic nuclei can be traced using H i 21 cm and OH-1667 MHz absorption lines to understand the fueling and feedback processes.
