A unified picture of Galactic and cosmological fast radio bursts [PDF]
, 2020 The discovery of a fast radio burst (FRB) in our galaxy associated with a magnetar (neutron star with strong magnetic field) has provided a critical piece of information to help us finally understand these enigmatic transients.

Moving solar radio bursts and their association with coronal mass ejections [PDF]
Astronomy & Astrophysics, 2021 Context. Solar eruptions, such as coronal mass ejections (CMEs), are often accompanied by accelerated electrons that can in turn emit radiation at radio wavelengths. This radiation is observed as solar radio bursts.

Periodic Bursts of Coherent Radio Emission from an Ultracool Dwarf [PDF]
, 2007 We report the detection of periodic (p = 1.96 hours) bursts of extremely bright, 100% circularly polarized, coherent radio emission from the M9 dwarf TVLM 513-46546. Simultaneous photometric monitoring observations have established this periodicity to be

Limits on Fast Radio Burst–like Counterparts to Gamma-Ray Bursts Using CHIME/FRB
The Astrophysical Journal, 2023 Fast radio bursts (FRBs) are a class of highly energetic, mostly extragalactic radio transients lasting for ∼milliseconds. While over 600 FRBs have been published so far, their origins are presently unclear, with some theories for extragalactic FRBs ...

Fast Radio Bursts from Interacting Binary Neutron Star Systems [PDF]
Astrophysical Journal, 2020 Recent observations of repeating fast radio bursts (FRBs) suggest that some FRBs reside in an environment consistent with that of binary neutron star (BNS) mergers. The bursting rate for repeaters could be very high and the emission site is likely from a

Fast Radio Bursts: An Extragalactic Enigma [PDF]
Annual Review of Astronomy and Astrophysics, 2019 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 sky with radiation energy densities at the source about ten

Density Fluctuations in the Solar Wind Based on Type III Radio Bursts Observed by Parker Solar Probe [PDF]
Astrophysical Journal Supplement Series, 2020 Radio waves are strongly scattered in the solar wind, so that their apparent sources seem to be considerably larger and shifted than the actual ones. Since the scattering depends on the spectrum of density turbulence, a better understanding of the radio ...

The Astrophysical Journal, 2023 Fast radio bursts (FRBs) are extragalactic radio transients with a millisecond duration and an extremely high brightness temperature. Very recently, some highly circularly polarized bursts were found in a repeater, FRB 20201124A. The significant circular

Afterglow upper limits for four short duration, hard spectrum gamma-ray bursts [PDF]
, 2001 We present interplanetary network localization, spectral, and time history information for four short-duration, hard spectrum gamma-ray bursts, GRB000607, 001025B, 001204, and 010119.

On the Origin of the Dark Gamma-Ray Bursts [PDF]
, 2005 The origin of dark bursts - i.e. that have no observed afterglows in X-ray, optical/NIR and radio ranges - is unclear yet. Different possibilities - instrumental biases, very high redshifts, extinction in the host galaxies - are discussed and shown to be
