Imaging Spectroscopy of Type U and J Solar Radio Bursts with LOFAR [PDF]
, 2017 Radio U-bursts and J-bursts are signatures of electron beams propagating along magnetic loops confined to the corona. The more commonly observed type III radio bursts are signatures of electron beams propagating along magnetic loops that extend into ...

Expanding fireball in magnetar bursts and fast radio bursts
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT A fireball of radiation plasma created near the surface of a neutron star (NS) expands under its own pressure along magnetic field lines, and produces photon emission and relativistic matter outflow. We comprehensively classify the expanding fireball evolution into five cases, and obtain the photospheric luminosity and the ...

Fundamental–Harmonic Pairs of Interplanetary Type III Radio Bursts
The Astrophysical Journal Letters, 2023 Type III radio bursts are not only the most intense but also the most frequently observed solar radio bursts. However, a number of their defining features remain poorly understood.

Ultra-Wideband Detection of 22 Coherent Radio Bursts on M Dwarfs [PDF]
, 2018 Coherent radio bursts detected from M dwarfs have some analogy with solar radio bursts, but reach orders of magnitude higher luminosities. These events trace particle acceleration, powered by magnetic reconnection, shock fronts (such as formed by coronal

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 ...

RADIO FLARES FROM GAMMA-RAY BURSTS [PDF]
The Astrophysical Journal, 2015 We present predictions of centimeter and millimeter radio emission from reverse shocks in the early afterglows of gamma-ray bursts with the goal of determining their detectability with current and future radio facilities. Using a range of GRB properties, such as peak optical brightness and time, isotropic equivalent gamma-ray energy and redshift, we ...

A deep learning method for the recognition of solar radio burst spectrum [PDF]
PeerJ Computer Science, 2022 Solar radiation is the excitation source that affects the weather in the atmosphere of the earth, and some solar activities such as flares and coronal mass ejections are often accompanied by radio bursts. The spectrum of solar radio bursts is helpful for

No detectable radio emission from the magnetar-like pulsar in Kes 75 [PDF]
, 2008 The rotation-powered pulsar PSR J1846-0258 in the supernova remnant Kes 75 was recently shown to have exhibited magnetar-like X-ray bursts in mid-2006.
