Inferring the distances of fast radio bursts through associated 21-cm absorption.

MARGALIT B. and LOEB A.

Abstract (from CDS):

The distances of fast radio burst (FRB) sources are currently unknown. We show that the 21-cm absorption line of hydrogen can be used to infer the redshifts of FRB sources, and determine whether they are Galactic or extragalactic. We calculate a probability of ∼10 per cent for the host galaxy of an FRB to exhibit a 21-cm absorption feature of equivalent width >=10 km s^-1. Arecibo, along with several future radio observatories, should be capable of detecting such associated 21-cm absorption signals for strong bursts of >=several Jy peak flux densities.
