Formation and collimation of relativistic MHD jets - simulations and radio maps

, 2013
We present results of magnetohydrodynamic (MHD) simulations of jet formation and propagation, discussing a variety of astrophysical setups. In the first approach we consider simulations of relativistic MHD jet formation, considering jets launched from ...

SMAP Satellite Microwave Radiometry to Monitor River Flow and Lake Level in the Lower Mekong Basin

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The NASA Soil Moisture Active Passive Mission (SMAP) satellite passive microwave radiometry (PMR) capability is demonstrated for measurements of river stage, river discharge, and lake level with in situ gauging data in the Lower Mekong Basin (LMB).

Deep‐Ultraviolet (DUV) Raman and Fluorescence of Perchlorates and Chlorates: Implications for the Detection of Oxychlorines by the SHERLOC Instrument in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...

A Case Study of One Local Severe Convection Process Caused by Meso‐β‐Scale Vortex in a Forming Southwest China Vortex in Spring With Large Eddy Simulation

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The fifth generation of ECMWF atmospheric reanalyses data (ERA5), operational observed data, S‐band radar data and Large Eddy Simulation (LES) tool were employed to investigate the evolution of local small‐scale convection in Ziyang City of Sichuan Province on 11 April 2022 in spring.

A Magnetohydrodynamic Model of the M87 Jet I: Superluminal Knot Ejections from HST-1 as Trails of Quad Relativistic MHD Shocks

, 2010
This is the first in a series of papers that introduces a new paradigm for understanding the jet in M87: a collimated relativistic flow in which strong magnetic fields play a dominant dynamical role.

On Optimal Parameterization for Mascon Solution of Surface Mass Changes From GRACE(‐FO) Satellite Gravimetry

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The Gravity Recovery and Climate Experiment (GRACE) and its successor, GRACE‐Follow On, play an important role in monitoring mass transport across the Earth. Compared to spherical harmonic solutions, mass concentration (mascon) solutions offer less signal leakage and a “higher” spatial resolution. How the shapes, sizes, and positions of mascon

Let There Be Neutrons! Hadronic Photoproduction from a Large Flux of High-energy Photons

The Astrophysical Journal
We propose that neutrons may be generated in high-energy, high-flux photon environments via photo-induced reactions on pre-existing baryons. These photohadronic interactions are expected to occur in astrophysical jets and surrounding material ...

3D NUMERICAL HYDRODYNAMICAL MODELS OF THE PRECESSING THICK ACCRETION DISK AND ON- AND OFF-STATE GENERATIONS IN MICROQUASARS

Odessa Astronomical Publications, 2017
The thick accretion disk and donor’s wind on the example of CYG X-1 are computed. The main aim of the present simulations is to calculate the precessing thick accretion disk and ON- and OFF-state generation by the methods of 3D numerical hydrodynamics ...
