In this article, the cross-shock electrostatic potential at the front of collisionless shocks plays a key role in the distribution of energy at the shock front, and a statistical study of the crossshock potential calculated for around 50 crossings of the terrestrial bow shock is presented.Abstract:
[1] The cross-shock electrostatic potential at the front of collision-less shocks plays a key role in the distribution of energy at the shock front. Multipoint measurements such as those provided by the Cluster II mission provide an ideal framework for the study of the cross-shock potential because of their ability to distinguish between temporal and spacial variations at the shock front. We present a statistical study of the cross-shock potential calculated for around 50 crossings of the terrestrial bow shock. The statistical dependency of the normalized (with resect to upstream ion kinetic energy) cross-shock potential (ΦK) on the upstream Alfven Mach number is in good agreement with analytical results that predict decrease of Φk with increasing Mach number.read more

TL;DR: In this paper, the authors address a subset of unresolved problems in collisionless shock physics from experimental point of view making use of multi-point observations onboard Cluster satellites, including determination of scales of fields and of a scale of electron heating, identification of energy source of precursor wave train, an estimate of the role of anomalous resistivity in energy dissipation process by means of measuring short scale wave fields, and direct observation of reformation process during one single shock front crossing.

TL;DR: In this paper, a detailed outline and discussion of the analysis techniques used to compare the relevance of different energy dissipation mechanisms at collisionless shock waves is presented. And the authors show that high-frequency, large-amplitude (>100 mV/m and/or > 1 nT) waves are ubiquitous in the transition region of collisionless shocks.
