Energetic particles are accelerated in rich profusion at sites throughout the heliosphere.
They come from solar flares in the low corona, from shock waves driven outward by coronal …

Solar flares are observed at all wavelengths from decameter radio waves to gamma-rays
beyond 1 GeV. This review focuses on recent observations in EUV, soft and hard X-rays …

Abstract Coronal Mass Ejections (CMEs) are plasma eruptions from the solar atmosphere
involving previously closed field regions which are expelled into the interplanetary medium …

Plasma and magnetic field data from the Helios 1/2 spacecraft have been used to
investigate the structure of magnetic clouds (MCs) in the inner heliosphere. 46 MCs were …

We summarize the occurrence of interplanetary coronal mass ejections (ICMEs) in the near‐
Earth solar wind during 1996–2002, corresponding to the increasing and maximum phases …

The heliospheric counterparts of coronal mass ejections (CMEs) at the Sun, interplanetary
coronal mass ejections (ICMEs), can be identified in situ based on a number of magnetic …

During the thirteenth encounter of the Parker Solar Probe (PSP) mission, the spacecraft
traveled through a topologically complex interplanetary coronal mass ejection (ICME) …

The structure of the dissipation region in collisionless magnetic reconnection is investigated
by means of kinetic particle-in-cell simulations and analytical theory. Analyses of simulations …

Geomagnetic storms are an important aspect of space weather and can result in significant
impacts on space-and ground-based assets. The majority of strong storms are associated …

We have obtained direct evidence for local magnetic reconnection in the solar wind using
solar wind plasma and magnetic field data obtained by the Advanced Composition Explorer …
