Fast radio bursts as standard candles for cosmology
s2720 Recently, fast radio bursts (FRBs) have become a thriving field in astronomy and cosmology.Due to their extragalactic and cosmological origin, they are useful to study the cosmic expansion and the intergalactic medium (IGM).In the literature, the dispersion measure (DM) of FRB has been considered extensively.It could be used as an indirect pr
