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 400 mJy for the observed pulse width of 7.8 ms and a flat spectrum across a 288-MHz band centred on 1374 MHz. The flat spectrum suggests that the pulse did not originate from a pulsar, but is consistent with radio-emitting magnetar spectra. The non-detection of subsequent bursts constrains any…

We report the discovery of several energetic radio bursts at 34 MHz, using the Gauribidanur radio telescope. The radio bursts exhibit two important properties associated with the propagation of

I present an empirical study of the properties of fast radio bursts (FRBs): gigahertz-frequency, dispersed pulses of extragalactic origin. I focus my investigation on a sample of 17 FRBs detected at

Fast Radio Burst Discovered in the Arecibo Pulsar ALFA Survey

Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arising

Dense magnetized plasma associated with a fast radio burst

The examination of archival data revealing Faraday rotation in the fast radio burst FRB 110523 is reported, indicating magnetization in the vicinity of the source itself or within a host galaxy.

A Galactic origin for the fast radio burst FRB010621

The recent detection of Fast Radio Bursts (FRBs) has generated strong interest in identifying the origin of these bright, non-repeating, highly dispersed pulses. The principal limitation in

A Fast Radio Burst Discovered in FAST Drift Scan Survey

We report the discovery of a highly dispersed fast radio burst (FRB), FRB 181123, from an analysis of ∼1500 hr of drift scan survey data taken using the Five-hundred-meter Aperture Spherical radio

On the Magnetospheric Origin of Repeating Fast Radio Bursts

A bright radio burst was newly discovered in SGR 1935+2154, which exhibits some fast radio burst (FRB)-like temporal and frequency properties, suggesting a neutron star (NS)/magnetar magnetospheric

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.

A Population of Fast Radio Bursts at Cosmological Distances

The detection of four nonrepeating radio transient events with millisecond duration in data from the 64-meter Parkes radio telescope in Australia indicates that these radio bursts had their origin outside the authors' galaxy, but it is not possible to tell what caused them.

Simultaneous View of FRB 180301 with FAST and NICER during a Bursting Phase

FRB 180301 is one of the most actively repeating fast radio bursts (FRBs) that has shown polarization angle changes in its radio burst emission, an indication for their likely origin in the




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

Simultaneous single-pulse observations of radio pulsars IV: flux density spectra of individual pulses

In this paper we demonstrate that a large, unexplored reservoir of information about pulsar emission exists, that is directly linked to the radiating particles and their radiation process: We present

Giant pulses from the Crab pulsar: A wide-band study

The Crab pulsar is well-known for its anomalous giant radio pulse emission. Past studies have concentrated only on the very bright pulses or were insensitive to the faint end of the giant pulse


As part of a survey for radio pulsars with the Parkes 64 m telescope, we have discovered PSR J1622−4950, a pulsar with a 4.3 s rotation period. Follow-up observations show that the pulsar has the

Multifrequency Observations of Radio Pulse Broadening and Constraints on Interstellar Electron Density Microstructure

We have made observations of 98 low Galactic latitude pulsars to measure pulse broadening caused by multipath propagation through the interstellar medium. Data were collected with the 305 m Arecibo

Enhanced pulsar and single pulse detection via automated radio frequency interference detection in multipixel feeds

Single pixel feeds on large aperture radio telescopes have the ability to detect weak (∼10 mJy) impulsive bursts of radio emission and sub-mJy radio pulsars. Unfortunately, in large-scale blind

Observational Characteristics of Giant Pulses and Related Phenomena

Evidence now exists that at least 14 pulsars emit distinctive pulses that are stronger and narrower than the average pulse. I review observations of these pulses in an effort to determine which

Pulsar spectra of radio emission

We have collected pulsar flux density observa- tions and compiled spectra of 281 objects. The database of Lorimer et al. (1995) has been extended to frequencies higher than 1.4 GHz and lower than 300

Further searches for Rotating Radio Transients in the Parkes Multi-beam Pulsar Survey

Ten new transient radio sources discovered in a re-analysis of the Parkes Multi-beam Pulsar Survey suggest that the population of transient radio-emitting neutron stars, and hence the neutron star population in general, may be even larger than initially predicted.

limiting flux density of the survey is about 0.2 mJy. At shorter or longer periods or higher dispersions, the sensitivity is reduced. Timing observations are carried out for pulsars discovered in the
