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

TL;DR: In this article, the authors presented a search for optical bursts from the repeating fast radio burst FRB 121102 using simultaneous observations with the high-speed optical camera ULTRASPEC on the 2.4m Thai National Telescope and radio observations with 100m Effelsberg Radio Telescope.

Are the distributions of fast radio burst properties consistent with a cosmological population

TL;DR: In this paper, Monte Carlo simulations of a cosmological population of fast radio bursts (FRBs) are performed, based on assumptions consistent with observations of their energy distribution, their spatial density as a function of redshift and the properties of the interstellar and intergalactic media.

The Fate of Neutron Star Binary Mergers
TL;DR: In this paper, the authors combine relativistic calculations of NS masses using realistic EOSs with Monte Carlo population synthesis based on the mass distribution of NS binaries in our Galaxy to predict the distribution of fates expected.

TL;DR: In this paper, the authors used the Very Large Array (VLA) for a 166-hour, millisecond imaging campaign to detect and precisely localize an FRB, which is the first millisecond timescale radio interferometric search for the new class of tran- sient known as fast radio bursts (FRBs).

Radio emissions from pulsar companions: a refutable explanation for galactic transients and fast radio bursts
Fabrice Mottez,Philippe Zarka +1 more
TL;DR: In this article, the authors investigated the radio signals generated by a body immersed in a pulsar wind, where a system of two stationary Alfven waves is attached to the body, provided that the wind is highly magnetized.

TL;DR: In this paper, theoretical background for pulsar observations is described. But pulsars as physical tools are not used as a physical tool for the measurement of pulsar properties.

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).
