Fast radio bursts (FRBs) have excessive dispersion measures (DMs) and an all-sky distribution, which point toward an extragalactic or even a cosmological origin. We develop a method to extract the mean host galaxy DM ( DM HG,loc ) and the characterized luminosity (L) of FRBs using the observed DM-Flux data, based on the assumption of a narrow luminosity distribution. Applying Bayesian inference to the data of 21 FRBs, we derive a relatively large mean host DM, i.e. DM HG,loc ∼ 270 pc cm −3 with a large dispersion. A relatively large DM HG of FRBs is also supported by the millisecond scattering times of some FRBs and the relatively small redshift z = 0.19273 of FRB 121102 (which gives DM HG,loc ∼ 210 pc cm −3 ). The large host galaxy DM may be contributed by the ISM or a near-source plasma in the host galaxy. If it is contributed by the ISM, the type of the FRB host galaxies would not be Milky Way (MW)-like, consistent with the detected host of FRB 121102. We also discuss the possibility of having a near-source supernova remnant (SNR), pulsar wind nebula (PWN) or HII region that gives a significant contribution to the observed DM HG .

“…Due to cosmological time dilation, the observed host DM value reads DM HG = DM HG,loc /(1 + z) (Ioka 2003). Considering the local inhomogeneity of the IGM (McQuinn 2014), we define a mean DM of the IGM as (Deng & Zhang 2014;)…”

Impulsive radio bursts that are detectable across cosmological distances constitute extremely powerful probes of the ionized Inter-Galactic Medium (IGM), intergalactic magnetic fields, and the properties of space-time itself. Their dispersion measures (DMs) will enable us to detect the "missing" baryons in the low-redshift Universe and make the first measurements of the mean galaxy halo profile, a key parameter in models of galaxy formation and feedback. Impulsive bursts can be used as cosmic rulers at redshifts exceeding 2, and constrain the dark energy equation-ofstate parameter, w(z) at redshifts beyond those readily accessible by Type Ia SNe. Both of these goals are realisable with a sample of ∼ 10 4 fast radio bursts (FRBs) whose positions are localized to within one arcsecond, sufficient to obtain host galaxy redshifts via optical follow-up. It is also hypothesised that gravitational wave events may emit coherent emission at frequencies probed by SKA1-LOW, and the localization of such events at cosmological distances would enable their use as cosmological standard sirens. To perform this science, such bursts must be localized to their specific host galaxies so that their redshifts may be obtained and compared against their dispersion measures, rotation measures, and scattering properties. The SKA can achieve this with a design that has a wide field-of-view, a substantial fraction of its collecting area in a compact configuration (80% within a 3 km radius), and a capacity to attach high-time-resolution instrumentation to its signal path.Advancing Astrophysics with the Square Kilometre Array

“…Although the progenitors of FRBs and the associated emission mechanisms are interesting in their own right, the apparent extragalactic origin, if true, can be used to probe the intergalactic medium and the geometry of the universe (Deng & Zhang 2014;Kulkarni et al 2014;McQuinn 2014;Zheng et al 2014;Masui & Sigurdson 2015). All reported bursts have been detected using single-dish telescopes that lack the angular resolution to obtain meaningful localizations, or even conclusively rule out a near-field or atmospheric origin.…”

Fast radio bursts (FRB) are millisecond-duration radio pulses with apparent extragalactic origins. All but two of the FRBs have been discovered using the Parkes dish, which employs multiple beams formed by an array of feed horns on its focal plane. In this paper, we show that (i) the preponderance of multiple-beam detections and (ii) the detection rates for varying dish diameters can be used to infer the index α of the cumulative fluence distribution function (the logN-logF function: α=1.5 for a non-evolving population in a Euclidean universe). If all detected FRBs arise from a single progenitor population, multiple-beam FRB detection rates from the Parkes telescope yield the constraint 0.52<α<1.0 with 90% confidence. Searches at other facilities with different dish sizes refine the constraint to 0.5<α<0.9. Our results favor FRB searches with smaller dishes, because for α<1 the gain in field of view for a smaller dish is more important than the reduction in sensitivity. Further, our results suggest that (i) FRBs are not standard candles, and (ii) the distribution of distances to the detected FRBs is weighted toward larger distances. If FRBs are extragalactic, these results are consistent with a cosmological population, which would make FRBs excellent probes of the baryonic content and geometry of the universe.
