We use multi-spacecraft Magnetospheric Multiscale (MMS) observations to investigate electric fields and ion reflection at a non-stationary collisionless perpendicular plasma shock. We identify sub-proton scale (5-10 electron inertial lengths) large-a

Solar Orbiter, a mission developed by the European Space Agency, explores in situ plasma across the inner heliosphere while providing remote-sensing observations of the Sun. Our study examines particle observations for the 30 October 2021 shock. The

Studies of shocks have long suggested that a shock can undergo cyclically self-reformation in a time scale of ion cyclotron period. This process has been proposed as a primary mechanism for energy dissipation and energetic particle acceleration at sh

Collisionless shocks in space plasmas are known to be capable of accelerating particles to very high energies. Particles are accelerated through a process called Fermi acceleration. However, this process can only act on particles with higher than the

Rosetta is a European spacecraft that will rendevouz with andfollow the comet 67P/Churyumov-Gerasimenko from 2014 to 2015. Among other instruments are two Langmuir probes that measure certain plasma parameters. This study aims to describe the photoem

Ion beam instabilities in the ion foreshock are an important source of ULF wave activity in near-Earth space. Foreshock 30-second waves are thought to be the main driver of Pc3 waves (10-45 s) observed routinely in the dayside magnetosphere. A handfu

Particle precipitation is a central aspect of space weather, as it strongly couples the magnetosphere and the ionosphere and can be responsible for radio signal disruption at high latitudes. We present the first hybrid-Vlasov simulations of proton pr
