  • 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% 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… CONTINUE READING
