A Relationship Between Fast Radio Burst Dispersion Measure and Host Galaxy Inclination

Lachlan Marnoch, Stuart D. Ryder, Sunil Simha +9

It is commonly thought that fast radio bursts (FRBs) trace star formation, and that they are produced by magnetars. Both hypotheses imply that their sources are hosted primarily (b…
