Two more fast radio burst’s host galaxies found

ASTRONOMERS HAVE HOMED IN on the host galaxies of two non-repeating fast radio bursts (FRBs), and their homes are not what the teams expected.

Until recently, astronomers have only been able to identify the host galaxy of that they had found the source of FRB 180924 — a millisecond-long flash that hasn’t repeated — using the 36-dish Australian Square Kilometre Array Pathfinder (ASKAP). Then, on July 2, Vikram Ravi (Caltech) and colleagues announced that they’d narrowed down the galaxy hosting a second non-repeater, FRB 190523. Both teams triangulated the sources using radio interferometry.
