COSMOLOGICAL IMPLICATIONS OF FAST RADIO BURST/GAMMA-RAY BURST ASSOCIATIONS

If a small fraction of fast radio bursts (FRBs) are associated with gamma-ray bursts (GRBs), as recently suggested by Zhang, the combination of redshift measurements of GRBs and dispersion measure (DM) measurements of FRBs opens a new window to study cosmology. At z < 2 where the universe is essentially fully ionized, detections of FRB/GRB pairs can give an independent measurement of the intergalactic medium portion of the baryon mass fraction, Ω b f IGM, of the universe. If a good sample of FRB/GRB associations are discovered at higher redshifts, the free electron column density history can be mapped, which can be used to probe the reionization history of both hydrogen and helium in the universe. We apply our formulation to GRBs 101011A and 100704A that each might have an associated FRB, and constrained Ω b f IGM to be consistent with the value derived from other methods. The methodology developed here is also applicable, if the redshifts of FRBs not associated with GRBs can be measured by other means.

Millisecond Magnetar Birth Connects FRB 121102 to Superluminous Supernovae and Long-duration Gamma-Ray Bursts (2017, background): “The known distance to the source could also aid such searches 7 There have been previous suggestions connecting FRBs and LGRB (Zhang 2014; Deng & Zhang 2014; Gao et al. 2014), but most of these are describing time coincidences.”
The birth of black holes: neutron star collapse times, gamma-ray bursts and fast radio bursts (2014, methodology): “…provide powerful evidence for the protomagnetar model for SGRBs, as well as the blitzar model of FRBs. FRB/SGRB associations may also be used to characterize the intergalactic baryon content of the Universe (Deng & Zhang 2014) through measurements of FRB dispersion measures and SGRB redshifts.”
