Jump-starting Relativistic Flows and the M87 Jet
The Astrophysical JournalWe point out the dominant importance of plasma injection effects of relativistic winds from pulsars and black holes. We demonstrate that outside the light cylinder, the magnetically dominated outflows sliding along the helical magnetic field move nearly ...

COVEN: Providing a Variety of Threshold‐Based Forecasts for the Outer Radiation Belt
Space Weather, Volume 24, Issue 6, June 2026.Abstract We present a suite of VAMPIRE (Van Allen belt Multi‐day Predictions by Implementing a Random Forest for Electrons) models capable of predicting if the outer radiation belt crosses set percentile thresholds. We use Random Forest classification models to predict if the daily ∼2 MeV electron flux level across the outer radiation belt exceeds ...

Characterization of the Western Pictor A Hotspot in Hard X-Rays with NuSTAR
The Astrophysical JournalThe origin of X-ray emission from the resolved kiloparsec-scale jets and hotspots of many active galactic nuclei remains uncertain, particularly where the X-ray emission is separate from the radio-optical synchrotron component.

Radiation from accelerated particles in relativistic jets with shocks, shear-flow, and reconnection
EPJ Web of Conferences, 2013 We have investigated particle acceleration and shock structure associated with an unmagnetized relativistic jet propagating into an unmagnetized plasma for electron-positron and electron-ion plasmas.

Unraveling the symmetry of Al5C3N
Acta Crystallographica Section B, Volume 82, Issue 3, Page 299-309, June 2026.From experimental and theoretical techniques employed in this thorough reexamination of the structure of Al5C3N, the crystal structure is better described in centrosymmetric space group P63/mmc (No. 194) rather than in the previously reported noncentrosymmetric space group P63mc (No. 186).High‐temperature ceramic compound Al5C3N belongs to the scarcely

STABILITY OF RELATIVISTIC FORCE-FREE JETS [PDF]
The Astrophysical Journal, 2009 We consider a two-parameter family of cylindrical force-free equilibria, modeled to match numerical simulations of relativistic force-free jets. We study the linear stability of these equilibria, assuming a rigid impenetrable wall at the outer cylindrical radius R_j.

Active Galactic Nuclei: Jets as the Source of Hadrons and Neutrinos
Acta Polytechnica CTU Proceedings, 2014 Active galactic nuclei are extragalactic sources, and their relativistic hot-plasma jets are believed to be the main candidates of the cosmic-ray origin, above the so-called knee region of the cosmic-ray spectrum.

Ion Cyclotron Waves Associated With Ionospheric Outflow at Jupiter
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The mechanism driving ion outflow from Jupiter's auroras remains to be determined. H+ ${\mathrm{H}}^{+}$ outflow has been observed with highly field‐aligned pitch angles consistent with acceleration by high‐altitude electrostatic potential structures.

Gamma-ray emission from early-type stars interacting with AGN jets [PDF]
, 2019 We study the interaction of early-type stars with the jets of active galactic nuclei. A bow-shock will form as a consequence of the interaction of the jet with the winds of stars and particles can be accelerated up to relativistic energies in these ...
