TLDR
A 30-jansky dispersed burst, less than 5 milliseconds in duration, located 3° from the Small Magellanic Cloud is found, which implies that it was a singular event such as a supernova or coalescence of relativistic objects.Abstract:
Pulsar surveys offer a rare opportunity to monitor the radio sky for impulsive burst-like events with millisecond durations. We analyzed archival survey data and found a 30-jansky dispersed burst, less than 5 milliseconds in duration, located 3 degrees from the Small Magellanic Cloud. The burst properties argue against a physical association with our Galaxy or the Small Magellanic Cloud. Current models for the free electron content in the universe imply that the burst is less than 1 gigaparsec distant. No further bursts were seen in 90 hours of additional observations, which implies that it was a singular event such as a supernova or coalescence of relativistic objects. Hundreds of similar events could occur every day and, if detected, could serve as cosmological probes.read more

Emission from a Pulsar Wind Nebula: Application to the Persistent Radio Counterpart of FRB 121102
Yu-Han Yang,Zi-Gao Dai +1 more
TL;DR: In this paper, a pulsar wind nebula powered by a magnetar without surrounding supernova ejecta was proposed as a radio counterpart of fast radio bursts (FRBs) and the model parameters were constrained by the spectrum of the counterpart emission, the size of the nebula, and the large but decreasing rotation measure (RM) of the repeating bursts.

A Dedicated Search for Low Frequency Radio Transient Astrophysical Events using ETA
TL;DR: In this article, the results of a search campaign using ETA, namely, a Crab giant pulse (CGP) search, were described and a software toolchain was developed for the analysis of data that includes calibration, radio frequency interference (RFI) mitigation, and incoherent dedispersion.

Cosmic Anisotropy and Fast Radio Bursts
TL;DR: In this paper, the authors tried to test the possible cosmic anisotropy with simulated FRBs and found that at least 2800, 190, 100 FRBs are competent to find the cosmic dipole with amplitude 0.01, 0.03, and 0.05, respectively.

TL;DR: The survey is proving to be extremely successful, with more than 600 pulsars discovered so far as discussed by the authors, and the number of newly discovered pulsars tend to be young, distant and of high radio luminosity, which is a valuable sample for studies of pulsar emission properties, the Galactic distribution and evolution of pulsars, and as probes of interstellar medium properties.

TL;DR: In this paper, Parkes telescope observations of neutral hydrogen (Hi) in the Small Magellanic Cloud (SMC) were combined with an Australia Telescope Compact Array (ATCA) aperture synthesis mosaic to obtain a set of images sensitive to all angular (spatial) scales between 98 arcsec (30 pc) and 4° (4 kpc).
