Frontiers in Astronomy and Space Sciences, 2021 Solar energetic particle (SEP) events are commonly separated in two categories: numerous “impulsive” events of relatively short duration, and a few “gradual” events, where SEP-intensities may stay enhanced over several days at energies up to several tens

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

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 ...

HIGH-FREQUENCY CUTOFF IN TYPE III BURSTS
Odessa Astronomical Publications, 2016 In this article we report about a group of solar bursts with high-frequency cutoff, observed on 19 August of 2012 near 8:23 UT, simultaneously by three different radio telescopes: the Ukrainian decameter radio telescope (8-33 MHz), the French Nançay ...

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.

Self-modulation of fast radio bursts [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Fast radio bursts (FRBs) are extreme astrophysical phenomena entering the realm of non-linear optics, a field developed in laser physics. A classical non-linear effect is self-modulation. We examine the propagation of FRBs through the circumburst environment using the idealized setup of a monochromatic linearly polarized GHz ...

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).
