Solar type III radio bursts are an important diagnostic tool in the understanding of solar
accelerated electron beams. They are a signature of propagating beams of nonthermal …

Most solar radio telescopes operate below∼ 18 GHz and cannot realize a complete
frequency coverage of the microwave spectrum, especially in the optically thin regime during …

Context. The Sun is an active star and the source of the largest explosions in the solar
system, such as flares and coronal mass ejections (CMEs). Flares and CMEs are powerful …

Radio bursts provide important diagnostics of energetic phenomena of the Sun. In particular,
bursts in decimetric and metric wavelengths probe the physical conditions and the energy …

A new radio spectropolarimeter for solar radio observation has been developed at Tohoku
University and installed on the Iitate Planetary Radio Telescope (IPRT) at the Iitate …

Context. Type III bursts and hard X-rays are both produced by flare energetic electron
beams. The link between both emissions has been investigated in many previous studies …

Aims. Understanding the properties of type III radio bursts in the solar corona and
interplanetary space is one of the best ways to remotely deduce the characteristics of solar …

Context. On 2022 January 20, the Energetic Particle Detector (EPD) on board Solar Orbiter
measured a solar energetic particle (SEP) event showing unusual first arriving particles from …

Radio observation is important for understanding coronal mass ejections (CMEs), coronal
shock waves, and high-energy electron acceleration. Here, we developed a new Chashan …

Narrowband spikes have been observed in solar flares for several decades. However, their
exact origin is still discussed. To contribute to understanding of these spikes, we analyze the …
