Fast Radio Bursts

, 2023
The era of fast radio bursts (FRBs) was open in 2007, when a very bright radio pulse of unknown origin was discovered occasionally in the archival data of Parkes Telescope. Over the past fifteen years, this mysterious phenomenon have caught substantial attention among the scientific community and become one of the hottest topic in high-energy ...

The Multiwavelength Counterparts of Fast Radio Bursts [PDF]

The Astrophysical Journal, 2020
Abstract The engines that produce extragalactic fast radio bursts (FRBs), and the mechanism by which the emission is generated, remain unknown. Many FRB models predict prompt multiwavelength counterparts, which can be used to refine our knowledge of these fundamentals of the FRB phenomenon. However, several previous targeted searches for

AGILE Observations of Fast Radio Bursts [PDF]

The Astrophysical Journal, 2021
Abstract We report on a systematic search for hard X-ray and γ-ray emission in coincidence with fast radio bursts (FRBs) observed by the AGILE satellite. We used 13 yr of AGILE archival data searching for time coincidences between exposed FRBs and events detectable by the MCAL (0.4–100 MeV) and GRID (50 MeV–30 GeV) detectors at ...

Nanolensed Fast Radio Bursts [PDF]

The Astrophysical Journal, 2017
Abstract It is suggested that fast radio bursts can probe gravitational lensing by clumpy dark matter objects that range in mass from 10−3 M ⊙–102 M ⊙. They may provide a more sensitive probe than observations of lensings of objects in the Magellanic Clouds, and ...

The host galaxy of a fast radio burst [PDF]

Nature, 2016
In recent years, millisecond-duration radio signals originating in distant galaxies appear to have been discovered in the so-called fast radio bursts. These signals are dispersed according to a precise physical law and this dispersion is a key observable quantity, which, in tandem with a redshift measurement, can be used for fundamental physical ...

Dark photon dark matter and fast radio bursts

European Physical Journal C: Particles and Fields, 2020
The nature of dark matter (DM) is still a mystery that may indicate the necessity for extensions of the Standard Model (SM). Light dark photons (DP) may comprise partially or entirely the observed DM density and existing limits for the DP DM parameter ...

ON ASSOCIATING FAST RADIO BURSTS WITH AFTERGLOWS [PDF]

The Astrophysical Journal Letters, 2016
ABSTRACT A radio source that faded over six days, with a redshift of z ≈ 0.5 host, has been identified by Keane et al. as the transient afterglow to a fast radio burst (FRB 150418). We report follow-up radio and optical observations of the afterglow candidate and find a source that is consistent with an active galactic nucleus.

Are There Multiple Populations of Fast Radio Bursts? [PDF]

The Astrophysical Journal Letters, 2018
Abstract The repeating FRB 121102 (the “repeater”) shows repetitive bursting activities and was localized in a host galaxy at z = 0.193. On the other hand, despite dozens of hours of telescope time spent on follow-up observations, no other fast radio bursts (FRBs) have been observed to repeat.

Constraints on the engines of fast radio bursts [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We model the sample of fast radio bursts (FRBs), including the newly discovered CHIME repeaters, using the decelerating synchrotron maser blast wave model of Metzger, Margalit & Sironi (2019), which built on earlier work by Lyubarsky (2014), Beloborodov (2017).

A Comprehensive Analysis of Repeating Fast Radio Bursts

The Astrophysical Journal Supplement Series, 2023
Nearly 700 fast radio burst (FRB) sources have been detected so far, of which 29 are found to burst out repeatedly. Although a firm connection between at least some FRBs and magnetars has been established, the trigger mechanism and radiation process in ...
