The INTEGRAL Mission
The INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL; Winkler et al. 2003; Kuulkers et al. 2021) was launched onboard a Proton-DM2 rocket on...

Generation of laboratory nanoflares from multiple braided plasma loops
Solar flares are intense bursts of electromagnetic radiation accompanied by energetic particles and hard X-rays. They occur when magnetic flux loops...

Detection of long-lasting aurora-like radio emission above a sunspot
Auroral radio emissions in planetary magnetospheres typically feature highly polarized, intense radio bursts, usually attributed to electron...

Relationships Between the Spectra of Near-Earth Proton Enhancements, Hard X-Ray Bursts, and CME Speeds
Some studies propose the transfer of flare-accelerated protons in an erupting flux rope until its reconnection with an open structure releases the...

Magnetar spin-down glitch clearing the way for FRB-like bursts and a pulsed radio episode
Magnetars are a special subset of the isolated neutron star family, with X-ray and radio emission mainly powered by the decay of their immense...

Stellar flares
Magnetic storms on stars manifest as remarkable, randomly occurring changes of the luminosity over durations that are tiny in comparison to the...

Quasi-Periodic Pulsations Detected in Ly \(\alpha \) and Nonthermal Emissions During Solar Flares
We report quasi-periodic pulsations (QPPs) with double periods during three solar flares (viz. SOL2011-Feb-15T01:44, SOL2011-Sep-25T04:31,...

Coherent radio bursts from known M-dwarf planet-host YZ Ceti
Observing magnetic star–planet interactions (SPIs) offers promise for determining the magnetic fields of exoplanets. Models of sub-Alfvénic SPIs...

How Do Shock Waves Define the Space-Time Structure of Gradual Solar Energetic Particle Events?
We revisit the full variety of observed temporal and spatial distributions of energetic solar protons in “gradual” solar energetic-particle (SEP)...
