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.

The Structure of the Giant Radio Fossil in the Ophiuchus Galaxy Cluster

The Astrophysical Journal
We present high-sensitivity follow-up observations of the giant fossil radio lobe in the Ophiuchus galaxy cluster with the upgraded Giant Metrewave Radio Telescope in the 125–250 and 300–500 MHz frequency bands.

On the variability of extragalactic sources in the decimeter range and their correlation with galactic structures [PDF]

It is shown that all of the extragalactic radio sources presently known are variable in the decimeter range (lambda or = 30 cm) and are projected on the large continuum radio structure of the galaxy: loops, spurs, ridges.

Detecting extragalactic axion-like dark matter with polarization measurements of fast radio bursts

Communications Physics
Axions or axion-like particles (ALPs) are one of the promising dark matter (DM) candidates. A prevalent method to detect axion-like DM is to seek periodic oscillation in the polarization angles (PAs) of linearly polarized light emitted from astrophysical

A uGMRT and MeerKAT Study of Radio Relics in the Low-mass Merging Cluster PSZ2 G200.95−28.16

The Astrophysical Journal
Diffuse radio sources known as radio relics are direct tracers of shocks in the outskirts of merging galaxy clusters. PSZ2 G200.95–28.16, a low-mass merging cluster ( M _500  = (2.7 ± 0.2) × 10 ^14 M _⊙ ), features a prominent radio relic, first ...
