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° 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… 

A model for fast extragalactic radio bursts

Bursts of millisecond duration were recently discovered in the 1 GHz band. There is a strong evidence that they come from $\sim 1 $ Gpc distances, which implies extraordinary high brightness

An Arecibo Search for Fast Radio Transients from M87

The possible origin of millisecond bursts from the giant elliptical galaxy M87 has been scrutinized since the earliest searches for extragalactic fast radio transients undertaken in the late 1970s.

A Fast Radio Burst Occurs Every Second throughout the Observable Universe

Recent multi-telescope observations of the repeating fast radio burst (FRB) FRB 121102 reveal a Gaussian-like spectral profile and associate the event with a dwarf metal-poor galaxy at a cosmological

Hyperflares of SGRs as an engine for millisecond extragalactic radio bursts

We propose that the strong millisecond extragalactic radio burst (mERB) discovered by Lorimer et al. (2007) may be related to a hyperflare from an extragalactic soft gamma-ray repeater. The expected

UvA-DARE (Digital Academic Repository) A repeating fast radio burst

Fast Radio Bursts are millisecond-duration astronomical radio pulses of unknown physical origin that appear to come from extragalactic distances 1–8 . Previous follow-up observations have failed to

Periodic Fast Radio Bursts from Luminous X-ray Binaries

The discovery of periodicity in the arrival times of the fast radio bursts (FRBs) poses a challenge to the oft-studied magnetar scenarios. However, models that postulate that FRBs result from

A repeating fast radio burst

These repeat bursts with high dispersion measure and variable spectra specifically seen from the direction of FRB 121102 support an origin in a young, highly magnetized, extragalactic neutron star.

Sub-second periodicity in a fast radio burst.

Fast radio bursts (FRBs) are millisecond-duration flashes of radio waves that are visible at distances of billions of light years1. The nature of their progenitors and their emission mechanism remain

On the detectability of extragalactic fast radio transients

Recent discoveries of highly dispersed millisecond radio bursts by Thornton et al. in a survey with the Parkes radio telescope at 1.4 GHz point towards an emerging population of sources at

A fast radio burst localized to a massive galaxy

Use of a specially built radio interferometer shows that a non-repeating fast radio burst is localized to a few-arcsecond region containing a single massive galaxy, and is perhaps derived from an old stellar population.



Transient radio bursts from rotating neutron stars

A search for radio sources that vary on much shorter timescales, finding eleven objects characterized by single, dispersed bursts having durations between 2 and 30 ms, suggesting origins in rotating neutron stars.

Discovery of 14 Radio Pulsars in a Survey of the Magellanic Clouds

A systematic survey of the Large and Small Magellanic Clouds for radio pulsars using the Parkes radio telescope and the 20 cm multibeam receiver has resulted in the discovery of 14 pulsars and the

Probing the cosmic reionization history and local environment of gamma‐ray bursts through radio dispersion

We discuss the effect of dispersion delay due to intervening ionized media in the radio emission of gamma-ray bursts (GRBs). For high-redshift GRBs (z ≥ 3), the ionized intergalactic medium (IGM)

The Brightest Pulses in the Universe: Multifrequency Observations of the Crab Pulsar’s Giant Pulses

We analyze the Crab pulsar at 10 frequencies from 0.43 to 8.8 GHz using data obtained at the Arecibo Observatory and report the spectral dependence of all pulse components and the rate of occurrence

On the evolution of the cosmic supernova rates

Ongoing searches for supernovae (SNe) at cosmological distances have recently started to provide a link between SN Ia statistics and galaxy evolution. We use recent estimates of the global history of

The irregularity spectrum in interstellar space

We analyze published data on the interstellar scintillations of three pulsars, using a theory based on the Markov approximation for strong scintillations. The data are found to be consistent with

The Cosmic Coalescence Rates for Double Neutron Star Binaries

We report on the newly increased event rates due to the recent discovery of the highly relativistic binary pulsar J0737-3039. Using a rigorous statistical method, we present the calculations reported

Searches for Fast Radio Transients

We discuss optimal detection of fast radio transients from astrophysical objects while taking into account the effects of propagation through intervening ionized media, including dispersion,

The large‐scale HI structure of the Small Magellanic Cloud

We combine new Parkes telescope observations of neutral hydrogen (Hi) in the Small Magellanic Cloud (SMC) with an Australia Telescope Compact Array (ATCA) aperture synthesis mosaic to obtain a set of

Discovery of Five Recycled Pulsars in a High Galactic Latitude Survey

We present five recycled pulsars discovered during a 21 cm survey of approximately 4150 deg2 between 15° and 30° from the Galactic plane using the Parkes radio telescope. One new pulsar, PSR
