Extracting host galaxy dispersion measure and constraining cosmological parameters using fast radio burst data

Abstract

The excessive dispersion measures (DMs) and high Galactic latitudes of fast radio bursts (FRBs) hint toward a cosmological origin of these mysterious transients. Methods of using measured DM and redshift $z$ to study cosmology have been proposed, but one needs to assume a certain amount of DM contribution from the host galaxy (DM${}_{\mathrm{HG}}$) in order to apply those methods. We introduce a slope parameter $\beta (z)\equiv d\ln ⟨{\mathrm{DM}}_{\mathrm{E}}⟩/d\ln z$ (where DM${}_{\mathrm{E}}$ is the observed DM subtracting the Galactic contribution), which can be directly measured when a sample of FRBs have $z$ measured. We show that $⟨\mathrm{D}{\mathrm{M}}_{\mathrm{HG}}⟩$ can be roughly inferred from $\beta$ and the mean values, $\overline{⟨\mathrm{D}{\mathrm{M}}_{\mathrm{E}}⟩}$ and $\bar{z}$, of the sample. Through Monte Carlo simulations, we show that the mean value of local host galaxy DM, $⟨\mathrm{D}{\mathrm{M}}_{\mathrm{HG},\mathrm{loc}}⟩$, along with other cosmological parameters (mass density ${\Omega }_m$ in the $\Lambda$CDM model, and the IGM portion of the baryon energy density ${\Omega }_b{f}_{\mathrm{IGM}}$) can be independently measured through MCMC fitting to the data.
