Mysterious Radio Bursts It has been uncertain whether single, short, and bright bursts of radio emission that have been observed are celestial or terrestrial in origin. Thornton et al. (p. 53; see the Perspective by Cordes) report the detection of four nonrepeating radio transient events with millisecond duration in data from the 64-meter Parkes radio telescope in Australia. The properties of these radio bursts indicate that they had their origin outside our galaxy, but it is not possible to… 

Radio Bursts, Origin Unknown

It is found that a burst rate of about 104 bursts per day over the entire sky has been deduced, and it is still early days for identifying the astrophysical origins of such common but (so far) rarely detected events.

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.

The discovery and scientific potential of fast radio bursts

Fast radio bursts (FRBs) are millisecond-time-scale bursts of coherent radio emission that are luminous enough to be detectable at cosmological distances. In this Review, I describe the discovery of

A direct localization of a fast radio burst and its host

The authors' observations are inconsistent with the fast radio burst having a Galactic origin or its source being located within a prominent star-forming galaxy, and the source appears to be co-located with a low-luminosity active galactic nucleus or a previously unknown type of extragalactic source.

The prevalence of repeating fast radio bursts

Fast radio bursts are extragalactic, sub-millisecond radio impulses of unknown origin1,2. Their dispersion measures, which quantify the observed frequency-dependent dispersive delays in terms of

The dispersion–brightness relation for fast radio bursts from a wide-field survey

A large-scale survey of fast radio bursts—short pulses of radio waves that seem to come from cosmological distances—finds 20 events, including both the nearest and the most energetic bursts observed so far, and demonstrates that there is a relationship between burst dispersion and brightness.

Fast radio bursts: the observational case for a Galactic origin

There are by now ten published detections of fast radio bursts (FRBs), single bright GHz-band millisecond pulses of unknown origin. Proposed explanations cover a broad range from exotic processes at

Statistical properties of fast radio bursts elucidate their origins: magnetars are favored over gamma-ray bursts

Fast radio bursts (FRBs) are extremely strong radio flares lasting several milliseconds, most of which come from unidentified objects at a cosmological distance. They can be apparently repeating or

A single fast radio burst localized to a massive galaxy at cosmological distance

Interferometric localization of the single-pulse FRB 180924 to a position 4 kiloparsecs from the center of a luminous galaxy at redshift 0.3214 indicates that some FRBs are clean probes of the baryonic component of the cosmic web.

The host galaxy of a fast radio burst

The discovery of a fast radio burst is reported and the identification of a fading radio transient lasting ~6 days after the event, which is used to identify the host galaxy and measure the galaxy’s redshift, which provides a direct measurement of the cosmic density of ionized baryons in the intergalactic medium.




Three years ago, the report of a solitary radio burst was thought to be the first discovery of a rare, impulsive event of unknown extragalactic origin. The extragalactic interpretation was based on

A search for dispersed radio bursts in archival Parkes Multibeam Pulsar Survey data

A number of different classes of potentially extra-terrestrial bursts of radio emission have been observed in surveys with the Parkes 64-m radio telescope, including ‘rotating radio transients’, the


We have searched for prompt radio emission from nine gamma-ray bursts (GRBs) with a 12 m telescope at 1.4 GHz, with a time resolution of 64 μs to 1 s. We detected single dispersed radio pulses with

A Bright Millisecond Radio Burst of Extragalactic Origin

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.

On the origin of a highly dispersed coherent radio burst

We discuss the possible source of a highly dispersed radio transient discovered in the Parkes Multibeam Pulsar Survey (PMPS). The pulse has a dispersion measure of 746 cm-3 pc, a peak flux density of

Soft Gamma-Ray Repeaters in Nearby Galaxies: Rate, Luminosity Function, and Fraction among Short Gamma-Ray Bursts

It was suggested that some of the short-duration gamma-ray bursts (GRBs) are giant flares of soft gamma-ray repeaters (SGRs) in nearby galaxies. To test this hypothesis, I have constructed a sample


We report the discovery of three pulsars whose large dispersion measures (DMs) and angular proximity to Sgr A* indicate the existence of a Galactic center population of neutron stars. The relatively

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 High Time Resolution Universe Pulsar Survey - I. System configuration and initial discoveries

With ∼30 per cent of the mid-latitude survey complete, the 13-beam multibeam receiver on the Parkes Radio Telescope has redetected 223 previously known pulsars and discovered 27 pulsars, five of which are millisecond pulsars.

An exceptionally bright flare from SGR 1806–20 and the origins of short-duration γ-ray bursts

Soft-γ-ray repeaters (SGRs) are galactic X-ray stars that emit numerous short-duration (about 0.1 s) bursts of hard X-rays during sporadic active periods. They are thought to be magnetars: strongly
