Fast Radio Bursts as probes of the late-time universe: a new insight on the Hubble tension

Surajit Kalita, Shruti Bhatporia, Amanda Weltman

Fast Radio Bursts (FRBs) are bright radio transient events, a subset of which have been localized to their host galaxies. Their high dispersion measures offer valuable insights int…
