Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Loss of relativistic electrons with energies above 0.5 MeV through the magnetopause, commonly referred to as magnetopause shadowing, has been extensively investigated using both simulations and observations. However, direct and systematic observational evidence remains limited. In this study, we extend a previously developed magnetopause model

, 2008 Nonthermal radiation observed from astrophysical systems containing relativistic jets and shocks, e.g., active galactic nuclei (AGNs), gamma-ray bursts (GRBs), and Galactic microquasar systems usually have power-law emission spectra.

Pressure-Driven Instabilities in Astrophysical Jets [PDF]
, 2008 Astrophysical jets are widely believed to be self-collimated by the hoop-stress due to the azimuthal component of their magnetic field. However this implies that the magnetic field is largely dominated by its azimuthal component in the outer jet region.

Assessment of the Generation of Traveling Ionospheric Disturbances by Solar Terminators
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract The generation of traveling ionospheric disturbances (TIDs) near solar terminators has been predicted, and several studies have reported the detection of TIDs associated with sunrise. However, there are also observations that do not show TID signatures at sunrise.

On the Universality of Energy Extraction from Black Hole Spacetimes
The Astrophysical Journal LettersThe launching of astrophysical jets provides the most compelling observational evidence for direct extraction of black hole (BH) spin energy via the Blandford–Znajek (BZ) mechanism.

, 2017 The distinctive morphology of head-tail radio galaxies reveals strong interactions between the radio jets and their intra-cluster environment, the general consensus on the morphology origin of head-tail sources is that radio jets are bent by violent ...

Different Transient Phenomena at the Edges of Traveling Foreshocks
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Past kinetic simulations and spacecraft observations have shown that traveling foreshocks (TFs) are bounded by either foreshock compressional boundaries (FCBs) or foreshock bubbles (FBs). Here we present four TFs with a different kind of structure appearing at one of their edges.

Evidence for Helical Magnetic Fields Associated with AGN Jets and the Action of a Cosmic Battery
Galaxies, 2018 Theoretical models for the electromagnetic launching of astrophysical jets have long indicated that this process should generate helical magnetic fields, which should then propagate outward with the jet plasma.

A photon breeding mechanism for the high-energy emission of relativistic jets
, 2006 We propose a straightforward and efficient mechanism for the high-energy emission of relativistic astrophysical jets associated with an exchange of interacting high-energy photons between the jet and the external environment.
