Catalogue and statistics of greater than 100 MeV solar proton events during solar cycles 23-25 from SOHO-ERNE observations

M. Jarry, C. Palmroos, E. Lavasa +12

The SPEARHEAD (specification, analysis, and re-calibration of high-energy particle data) project, funded by the European Union Horizon Europe programme, enhances the accuracy and u…

In-flight calibration of RADEM, the JUICE mission radiation monitor

Marco Pinto, Francisca Santos, António Gomes +7

The RADiation-hard Electron Monitor (RADEM) aboard the Jupiter Icy Moons Explorer (JUICE), launched on 14 April 2023, measures high-energy protons and electrons during the cruise p…

Imaging and spectropolarimetric observations of a band-split type II solar radio burst with LOFAR

S. Normo, D. E. Morosan, P. Zhang +2

Type II solar radio bursts are generated by electrons accelerated by coronal shock waves. They appear in dynamic spectra as lanes drifting from higher to lower frequencies at the p…

Resolving spatial and temporal shock structures using LOFAR observations of type II radio bursts

D. E. Morosan, I. C. Jebaraj, P. Zhang +6

Collisionless shocks are one of the most powerful particle accelerators in the Universe. In the heliosphere, type II solar radio bursts are signatures of electrons accelerated by c…
