“…Radio telescopes are being adapted to detect many more and aiming to distribute alerts in close to real time (e.g., Petroff, 2017). The origin of these bursts is undetermined and the models range from neutron-star collapse to black holes, neutron star or white dwarf mergers and non-cataclysmic pulsar events (for a review, see Rane & Lorimer, 2017). There is one FRB source which has repeated tens of times (Spitler et al 2016), while all other observed FRBs have not been observed to repeat (although it is possible that repeats have been missed due to instrument sensitivity limitations and survey strategies; Petroff et al, 2015).…”

“…Figure 2 suggests that even for the largest intrinsic wait time of 50 seconds, on average it would only take ∼ 25 hours to detect a repeat pulse at this redshift. Given the > 200 hours (Rane & Lorimer 2017) spent looking for repeatability, the probability of not detecting a repeat pulse is 3.3×10 −4 . This suggests that not all FRB sources might be repeatable, though this is still highly dependent on the wait timescales modelled.…”

“…Similarly, the Parkes radio telescope is only capable of detecting repeat pulses from low redshift z ≤ 0.1 FRB sources given the modelled observation time and repeat rate. The non-detection of a repeat pulse from FRB 010724 despite having spent > 200 hours on follow-up observations (Rane & Lorimer 2017) rules out the possibility of it repeating with the same rate as FRB 121102.…”

We present Monte-Carlo simulations of a cosmological population of repeating fast radio burst (FRB) sources whose comoving density follows the cosmic star formation rate history. We assume a power-law model for the intrinsic energy distribution for each repeating FRB source located at a randomly chosen position in the sky and simulate their dispersion measures (DMs) and propagation effects along the chosen lines-of-sight to various telescopes. In one scenario, an exponential distribution for the intrinsic wait times between pulses is chosen, and in a second scenario we model the observed pulse arrival times to follow a Weibull distribution. For both models we determine whether the FRB source would be deemed a repeater based on the telescope sensitivity and time spent on follow-up observations. We are unable to rule out the existence of a single FRB population based on comparisons of our simulations with the longest FRB follow-up observations performed. We however rule out the possibility of FRBs 171020 and 010724 repeating with the same rate statistics as FRB 121102 and also constrain the slope of a power-law fit to the FRB energy distribution to be −2.0 < γ < −1.0. All-sky simulations of repeating FRB sources imply that the detection of singular events correspond to the bright tail-end of the adopted energy distribution due to the combination of the increase in volume probed with distance, and the position of the burst in the telescope beam.

“…More than 30 FRBs have been discovered since 2007, with various telescopes (Parkes, Green Bank Telescope, Arecibo, UTMOST, ASKAP) over a range of frequencies (1.4 GHz, 800 MHz, 2 GHz, 4-8 GHz), of which only 24 FRBs have been published (see [13] for references). However only one of these 24 FRBs, the one discovered at the Arecibo observatory, has been seen to repeat, despite telescopes having spent several hundreds of hours re-observing the positions of known FRBs [14]. Leading progenitor models for FRBs range from binary neutron star mergers (e.g.…”

The recent development of sensitive, high time resolution instruments at radio telescopes has enabled the discovery of millisecond duration fast radio bursts (FRBs). The FRB class encompasses a number of single pulses, many unique in their own way, so far hindering the development of a consensus for their origin. The key to demystifying FRBs lies in discovering many of them in realtime in order to localise them and identity commonalities. Despite rigorous follow-up, only one FRB has been seen to repeat suggesting the possibility of there being two independent classes of FRBs and thus two classes of possible progenitors. This paper discusses recent developments in the field, the FRB-GRB connection, some of the open questions in FRB astronomy and how the next generation telescopes are vital in the quest to understand this enigmatic population.
