Pune: Astronomers from the National Centre of Radio Astrophysics (NCRA-TIFR) in Pune, and the University of California, Santa Cruz, have discovered the first direct evidence of a recent merger in a fast radio burst galaxy.
The authors used the Giant Metrewave Radio Telescope (GMRT) observations of the 21cm line of atomic hydrogen to study the gas distribution in the fast radio burst (FRB) host galaxy. The discovery showcases the ability of the GMRT to identify such mergers.
