“…Fast radio bursts (FRBs) are mysterious transient radio sources of millisecond duration [1][2][3][4][5][6][7][8][9][10]. More than a decade passed since their discovery [11,12], but the origin of FRBs is still unknown to date [6][7][8][9][10].…”

“…To date, the intrinsic FRB redshift distribution is poorly known, mainly due to the deficiency in FRBs with identified redshifts [37]. As a crude rule of thumb, the FRB redshift z ∼ DM/(1000 pc cm −3 ) [2]. The detailed theoretical DM− z relation was given by e.g.…”

“…For a long time, it has been speculated that the FRB distribution tracks the cosmic star formation history (SFH) [1][2][3][4][5][6][7][8][9][10]. Recently, the landmark Galactic FRB 200428 associated with the young magnetar SGR 1935+2154 [50][51][52][53] confirmed that at least some (if not all) FRBs originate from young magnetars.…”

Currently, fast radio bursts (FRBs) have become a very active field in astronomy and cosmology. However, the origin of FRBs is still unknown to date. The studies on the intrinsic FRB distributions might help us to reveal the possible origins of FRBs, and improve the simulations for FRB cosmology. Recently, the first CHIME/FRB catalog of 536 events was released. Such a large uniform sample of FRBs detected by a single telescope is very valuable to test the FRB distributions. Later, it has been claimed that the FRB distribution model tracking the cosmic star formation history (SFH) was rejected by the first CHIME/FRB catalog. In the present work, we consider some new FRB distribution models, and find that many of them can be fully consistent with the CHIME/FRB observational data for some suitable model parameters. In particular, a suppressed evolution with respect to SFH is commonly found for FRBs. These results might shed light on the origin of FRBs and FRB cosmology.

“…Currently, fast radio bursts (FRBs) have become a thriving field in astronomy and cosmology [1][2][3][4][5][6][7][8][9][10][11][12]. Since their first discovery [13,14], an extragalactic/cosmological origin is strongly suggested to FRBs, due to the large dispersion measure (DM) of observed FRBs well in excess of the Galactic value.…”

Nowadays, fast radio bursts (FRBs) have been a promising probe for astronomy and cosmology. However, it is not easy to identify the redshifts of FRBs to date. Thus, no sufficient actual FRBs with identified redshifts can be used to study cosmology currently. In the past years, one has to use the simulated FRBs with " known " redshifts instead. To simulate an FRB, one should randomly assign a redshift to it from a given redshift distribution. But the actual redshift distribution of FRBs is still unknown so far. In the present work, we study the effect of various redshift distributions on cosmological constraints. We find that different redshift distributions lead to different constraining abilities from the simulated FRBs. This result emphasizes the importance to find the actual resdshift distribution of FRBs, and reminds us of the possible bias in the FRB simulations due to the redshift distributions.

“…Fast radio bursts (FRBs) are a newly discovered and enigmatic class of astrophysical transients characterized by non-periodic millisecond-scale radio flashes. Their high dispersion measures (DM) [8,9] and prevalence at high Galactic latitudes suggest that FRBs are likely of extragalactic origin. To date, a total of 75 FRBs have been detected, but the estimated all-sky rate of detectable FRBs is on the order of thousands per day [10], and this disparity is driven in large part by the narrow field of view of most radio telescopes.…”

Although IceCube has discovered a diffuse astrophysical neutrino flux, the underlying sources of these neutrinos remain unknown. Transient astrophysical objects, such as fast radio bursts (FRBs), could explain a large percentage of the measured flux. We present the analysis techniques of IceCube searches for MeV to TeV neutrinos from FRBs. As no significant correlation between IceCube neutrinos and FRBs has been found, we present the first limit on MeV neutrino emission from FRBs and the most constraining limits for neutrinos with GeV to TeV energies. We also describe the prospects for future IceCube neutrino searches coinciding with FRB detections from next generation radio interferometers.
