The physics of collisionless shocks is a very broad topic which has been studied for more
than five decades. However, there are a number of important issues which remain …

Shock waves propagating in collisionless heliospheric and astrophysical plasmas have
been studied extensively over the decades. One prime motivation is to understand the …

A new mechanism for the acceleration of pickup ions by repeated reflections from the
electrostatic cross shock potential of a quasi‐perpendicular shock is presented. The …

We present observations of intense, bipolar, electrostatic structures in the transition region of
the terrestrial bow shock from the Wind spacecraft. The electric field signatures are on the …

The electron heating and the electrostatic potential jump across collisionless shocks play an
important, if not dominant, role in the electron momentum balance. We present here a survey …

Perpendicular collisionless shocks are studied by means of two‐dimensional hybrid (particle
ion, fluid electron) simulations, with emphasis on the relaxation of the highly anisotropic ion …

Recent observations indicate that low‐altitude (below 1500 km) ion energization and
thermal ion upwelling are colocated in the convective flow reversal region. In this region the …

The possibility is examined of obtaining information about the orientation and state of motion
of the magnetopause current layer from the convection electric field, Ec=− v× B, calculated …

One‐dimensional (1‐D) full particle simulations of almost perpendicular supercritical
collisionless shocks are presented. The ratio of electron plasma frequency ωpe to …

We present the first quantified measure of the energy dissipation rates, due to wave‐particle
interactions, in the transition region of the Earth's collisionless bow shock using data from …
