BepiColombo at Mercury: Three Flybys, Three Magnetospheres

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances package on the Mercury Planetary Orbiter designed to study magnetospheric dynamics.

Statistical Estimate of the Magnetopause Reconnection Rate as a Function of the Interplanetary Magnetic Field Clock Angle

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The magnetic reconnection rate at the magnetopause is crucial for solar wind and magnetosphere coupling. However, direct measurement is challenging due to inherent uncertainties and limited electron diffusion region statistics, hindering understanding of the guide field's influence on the normalized reconnection rate.

Astrophysical Jets: A Review [PDF]

Proceedings of Frontier Research in Astrophysics — PoS(FRAPWS2014), 2016
This review is part of a series that considers our evolving understanding of the nature of astrophysical jets. These have been defined as linear structures on the sky, typically bi-polar, and originating from a common source. Jets are associated with outflows originating from accretion processes in star-forming regions,compact objects (such as ...

Spatial Distributions of Energetic Electrons and Energetic Ions in the Tail Reconnection Region: Cluster Observations and PIC Simulations

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.

Boosted dark matter from Centaurus A and its detection

Journal of High Energy Physics
Dark matter can be boosted by high energy particles in astrophysical environments through elastic scattering. We study the production of boosted dark matter via scattering with electrons in the relativistic jet of the closest active galactic nucleus ...

Future Perspectives on Black Hole Jet Mechanisms: Insights from Next-Generation Observatories and Theoretical Developments

Universe
Black hole jets represent one of the most extreme manifestations of astrophysical processes, linking accretion physics, relativistic magnetohydrodynamics, and large-scale feedback in galaxies and clusters. Despite decades of observational and theoretical

An extremely high velocity molecular jet surrounded by an ionized cavity in the protostellar source Serpens SMM1

, 2016
We report ALMA observations of a one-sided, high-velocity ($\sim$80 km s$^{-1}$) CO($J = 2 \rightarrow 1$) jet powered by the intermediate-mass protostellar source Serpens SMM1-a. The highly collimated molecular jet is flanked at the base by a wide-angle

Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Accelerometer Data Transplant for Future Satellite Gravimetry

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Accurate monitoring of the Earth's gravity field is crucial for understanding mass redistribution processes related to climate change, hydrology, and geodynamics. The Gravity Recovery and Climate Experiment (GRACE) and its successor, GRACE Follow‐On (GRACE‐FO), have provided invaluable satellite gravimetry data through low‐low satellite‐to ...

Helical Magnetic Field in a Massive Protostellar Jet

The Astrophysical Journal Letters
Highly collimated outflows (jets) are observed across a wide range of astrophysical systems involving the accretion of material onto central objects, from supermassive black holes in active galaxies to proto-brown dwarfs and stellar-mass black holes ...
