The context of the term 'geophysics' has changed considerably during the second half of the
past century. Well into the fifties the key interest of non-exploratory non-applied geophysics …

Magnetic holes at the ion-to-electron kinetic scale (KSMHs) are one of the extremely small
intermittent structures generated in turbulent magnetized plasmas. In recent years, the …

Magnetic holes (MHs)—depressions in magnetic field strength—have been reported around
dipolarization fronts (DFs), but their generation and dynamics remain elusive owing to the …

The solar wind plasma is characterized by unequal effective kinetic temperatures defined in
perpendicular and parallel directions with respect to the ambient magnetic field. For …

This paper formulates a velocity moment-based quasi-linear theory that combines the
impacts of weakly unstable proton–cyclotron-(or, equivalently, electromagnetic ion cyclotron) …

Properties of the electron mirror instability and its competition with the usually dominant
whistler (electron cyclotron) instability driven by the electron perpendicular temperature …

In the magnetosheath, intense whistler mode waves, called “Lion roars,” are often detected
in troughs of magnetic field intensity in mirror mode structures. Using data obtained by the …

The charged particles in the solar wind are often observed to possess a nonthermal tail in
the velocity distribution function, a feature that can be fitted with the Kappa model. The …

The small-scale mirror mode excited by electron dynamics is a fundamental physical
process, attracting research interest in space, laboratory, and astrophysical plasma physics …

Magnetic holes have been frequently observed in the Earth's magnetosheath and are
believed to be the consequence of the nonlinear evolution of the mirror instability. Mirror …
