Fast radio bursts at the dawn of the 2020s

  title={Fast radio bursts at the dawn of the 2020s},
  author={Emily Petroff and Jason W. T. Hessels and Duncan R. Lorimer},
Since the discovery of the first fast radio burst (FRB) in 2007, and their confirmation as an abundant extragalactic population in 2013, the study of these sources has expanded at an incredible rate. In our 2019 review on the subject we presented a growing, but still mysterious, population of FRBs – 60 unique sources, 2 repeating FRBs, and only 1 identified host galaxy. However, in only a few short years new observations and discoveries have given us a wealth of information about these sources… Expand

Burst timescales and luminosities link young pulsars and fast radio bursts
Fast radio bursts (FRBs) are extragalactic radio flashes of unknown physical origin (Petroff et al. 2019; Cordes & Chatterjee 2019). Their high luminosities and short durations require extreme energyExpand


Fast Radio Bursts: An Extragalactic Enigma
We summarize our understanding of millisecond radio bursts from an extragalactic population of sources. Fast radio bursts (FRBs) occur at an extraordinary rate, thousands per day over the entire skyExpand
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 arisingExpand
A repeating fast radio burst source in a globular cluster
Fast radio bursts (FRBs) are extremely luminous and brief radio flashes originating from other galaxies (Petroff et al. 2019). Progressing our understanding of the FRB phenomenon is limited by theirExpand
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 ofExpand
The Repeating Fast Radio Burst FRB 121102 as Seen on Milliarcsecond Angular Scales
The millisecond-duration radio flashes known as fast radio bursts (FRBs) represent an enigmatic astrophysical phenomenon. Recently, the sub-arcsecond localization (∼100 mas precision) of FRB 121102Expand
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. Expand
A repeating fast radio burst source localized to a nearby spiral galaxy
Only one repeating fast radio burst has been localized, to an irregular dwarf galaxy; now another is found to come from a star-forming region of a nearby spiral galaxy, suggesting that repeating FRBs may have a wide range of luminosities, and originate from diverse host galaxies and local environments.

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.

Sub-second periodicity in a fast radio burst
The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we reportExpand
Fast Radio Burst Morphology in the First CHIME/FRB Catalog
We present a synthesis of fast radio burst (FRB) morphology (the change in flux as a function of time and frequency) as detected in the 400–800 MHz octave by the FRB project on the Canadian HydrogenExpand
