“Slow” Radio Bursts from Galactic Magnetars? [PDF]

The Astrophysical Journal Letters, 2021
Abstract Recently, one fast radio burst (FRB), FRB 200428, was detected from the Galactic magnetar soft gamma-ray repeater (SGR) J1935+2154 during one X-ray burst. This suggests that magnetars can make FRBs. On the other hand, the majority of X-ray bursts from SGR J1935+2154 are not associated with FRBs.

Electron Cyclotron Maser Emission and the Brightest Solar Radio Bursts

The Astrophysical Journal
This paper investigates the incidence of coherent emission in solar radio bursts, using a revised catalog of 3800 solar radio bursts observed by the Nobeyama Radio Polarimeters from 1988 to 2023.

Identification of a Likely Radio Counterpart of the Rapid Burster [PDF]

, 1999
We have identified a likely radio counterpart to the low-mass X-ray binary MXB 1730-335 (the Rapid Burster). The counterpart has shown 8.4 GHz radio on/off behavior correlated with the X-ray on/off behavior as observed by the RXTE/ASM during six VLA ...

Coronal mass ejections, type II radio bursts, and solar energetic particle events in the SOHO era [PDF]

Annales Geophysicae, 2008
Using the extensive and uniform data on coronal mass ejections (CMEs), solar energetic particle (SEP) events, and type II radio bursts during the SOHO era, we discuss how the CME properties such as speed, width and solar-source longitude decide ...

Extragalactic dispersion measures of fast radio bursts

, 2015
Fast radio bursts show large dispersion measures, much larger than the Galactic dispersion measure foreground. Therefore,they evidently have an extragalactic origin. We investigate possible contributions to the dispersion measure from host galaxies.

Formation of "Lightnings" in a Neutron Star Magnetosphere and the Nature of RRATs

, 2011
The connection between the radio emission from "lightnings" produced by the absorption of high-energy photons from the cosmic gamma-ray background in a neutron star magnetosphere and radio bursts from rotating radio transients (RRATs) is investigated ...

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS

Solar-Terrestrial Physics, 2020
We have investigated the cause of three “isolated” negative radio bursts recorded one after another at several frequencies in the 1–17 GHz range at the Nobeyama Radio Observatory, Ussuriysk Astrophysical Observatory, and Learmonth Solar Observatory on ...

A New X-Ray and Radio Burst Activity from the Magnetar SGR 1935+2154

The Astrophysical Journal Supplement Series
SGR 1935+2154 has emerged as the most active magnetar in recent years, exhibiting X-ray burst activity nearly annually and emitting a fast radio burst (FRB 200428 (FRB1)) in its 2020 April activity, for the first time from a Milky Way source, accompanied
