Quasiperiodic Polarized Emissions from Kink Structure in Magnetized Relativistic Jets
The Astrophysical JournalRecent polarimetric observations of blazars indicate the development of current-driven (CD) kink instability after passing the recollimation shocks in the relativistic jets and association with quasiperiodic oscillations (QPOs).

Leptonic and Hadronic Radiative Processes in Supermassive-Black-Hole Jets
Galaxies, 2020 Supermassive black holes lying in the center of galaxies can launch relativistic jets of plasma along their polar axis. The physics of black-hole jets is a very active research topic in astrophysics, owing to the fact that many questions remain open on ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Constraining Electron‐Impact Ionization of O2 Through UV Aurora Observations at Ganymede
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract While photoionization rates of Ganymede's O2 ${\mathrm{O}}_{2}$ dominated atmosphere are well constrained, the contribution of electron‐impact ionization is rather uncertain. Previous quantitative estimates have relied on assumptions about densities and energy distributions of precipitating electrons, or on rare spacecraft measurements that ...

The Astrophysical JournalSpinning supermassive black holes (BHs) in active galactic nuclei magnetically launch relativistic collimated outflows, or jets. Without angular momentum supply, such jets are thought to perish within 3 orders of magnitude in distance from the BH, well ...

Analysis of Chorus Wave Power on Burst‐Mode Timescales During the Van Allen Probes Era
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Interactions between whistler‐mode chorus waves and electrons are a key driver of dynamics in Earth's radiation belts. These global dynamics are often described using Fokker‐Planck diffusion models. Whilst, in many cases, such models effectively describe the large scale changes within the region, they often rely upon spatially and temporally ...

Relativistic baryonic jets from an ultraluminous supersoft X-ray source
, 2015 The formation of relativistic jets by an accreting compact object is one of the fundamental mysteries of astrophysics. Although the theory is poorly understood, observations of relativistic jets from systems known as microquasars (compact binary stars ...

Transverse stability of relativistic two-component jets
, 2007 Context.Astrophysical jets from various sources seem to be stratified, with a fast inner jet and a slower outer jet. As it is likely that the launching mechanism for each component is different, their interface will develop differential rotation ...
