Finding Local Parallel Electric Fields in Magnetotail Reconnection Using a Two‐Spacecraft Method

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the use of a novel two‐spacecraft Liouville‐mapping method using data from the Magnetospheric Multiscale mission to determine local magnetic‐field‐aligned (parallel) electric fields in the Earth's magnetotail. The method detects the presence of local acceleration potentials by mapping phase‐space density between electron ...

Relativistic Particle-In-Cell Simulation Studies of Prompt and Early Afterglows from GRBs

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

High--Resolution 3D Simulations of Relativistic Jets

, 1999
We have performed high-resolution 3D simulations of relativistic jets with beam flow Lorentz factors up to 7, a spatial resolution of 8 cells per beam radius, and for up to 75 normalized time units to study the morphology and dynamics of 3D relativistic ...

Relativistic Hydrodynamic Flows Using Spatial and Temporal Adaptive Structured Mesh Refinement

, 2007
Astrophysical relativistic flow problems require high resolution three-dimensional numerical simulations. In this paper, we describe a new parallel three-dimensional code for simulations of special relativistic hydrodynamics (SRHD) using both spatially ...

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, while ...

Synchrotron-limited Particle Acceleration in Relativistic Shearing Flows

The Astrophysical Journal
Fermi-type shear particle acceleration is a promising mechanism for sustaining ultrarelativistic particles along the kiloparsec scale jets in active galactic nuclei.

POWERFUL RELATIVISTIC JETS IN SPIRAL GALAXIES [PDF]

International Journal of Modern Physics: Conference Series, 2012
The discovery of high-energy (E > 100 MeV) γ rays from Narrow-Line Seyfert 1 Galaxies (γ-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (AGN). Although the jet emission is similar to that of blazars and radio galaxies, γ-NLS1s have some striking differences: relatively small masses (106-8 M⊙),

A Simulation Study of Low-power Relativistic Jets: Flow Dynamics and Radio Morphology of FR-I Jets

The Astrophysical Journal
Radio galaxies are classified into two primary categories based on their morphology: center-brightened FR-I and edge-brightened FR-II. It is believed that the jet power and interactions with the ambient medium govern the deceleration and decollimation of
