DOI: 10.1007/s11431-016-9008-3
Abstract: On January 21, 2015, a sharp increase of the solar wind dynamic pressure impacted the magnetosphere. The magnetopause moved inward to the region L< 8 without causing a geomagnetic storm. The flux of the relativistic… read more here.

DOI: 10.1007/s11431-017-9067-y
Abstract: Previous theoretical studies have shown that dayside chorus can produce butterfly distribution of energetic electrons in the Earth’s radiation belts by preferentially accelerating medium pitch angle electrons, but this requires the further confirmation from high-resolution… read more here.

DOI: 10.1029/2020gl088052
Abstract: Whistler‐mode hiss waves generally determine MeV electron lifetimes inside the plasmasphere. We use Van Allen Probes measurements to provide the first comprehensive statistical survey of plasmaspheric hiss‐driven quasi‐linear pitch‐angle diffusion rates and lifetimes of MeV… read more here.

DOI: 10.1029/2020gl089994
Abstract: Chorus waves with the frequency usually between 0.1 and 0.8 equatorial electron gyrofrequency fce can accelerate energetic electrons to relativistic energies (several mega‐electron volts, MeV). Here, we report a unique event that both regular chorus… read more here.

DOI: 10.1103/physrevlett.129.135101
Abstract: Electromagnetic ion cyclotron waves are expected to pitch-angle scatter and cause atmospheric precipitation of relativistic (>1 MeV) electrons under typical conditions in Earth's radiation belts. However, it has been a long-standing mystery how relativistic electrons in… read more here.
