Space physics explores the dynamic environment surrounding our planet and the wider solar system, focusing on how charged particles, magnetic fields, and solar winds interact with celestial bodies. This field helps us understand phenomena like auroras, space weather that can disrupt satellites, and the fundamental behavior of plasma in the vacuum of space. It bridges the gap between astronomy and particle physics, revealing the invisible forces that shape our cosmic neighborhood.

This paper presents a statistical processing pipeline using a scaled Vecchia Gaussian process to overcome noise challenges in ISS-based EP-EE instrument data, enabling the recovery of ionospheric signals and increased data coverage during the Solar Cycle 25 maximum.
This paper presents the first comprehensive VLBI observations of Galileo navigation satellites using the Australian AuScope array, demonstrating the feasibility of deriving station coordinates and establishing inter-technique ties between VLBI and GNSS reference frames to support future geodetic co-location missions like ESA's Genesis.
This study compares high-Mach-number interplanetary and terrestrial quasi-parallel shocks to reveal that while Foreshock Compressive Structures initiate under similar upstream conditions, the interplanetary shock fails to develop fully evolved nonlinear structures due to a spatially limited growth zone and a lack of global curvature that inhibits the lateral supply of energetic ions.
This study utilizes the uncoupled Energetic Particle Radiation Environment Model (EPREM) to systematically analyze how variations in physical parameters, such as diffusion and shock profile, influence the morphology and longitudinal spread of simulated widespread solar energetic particle events, revealing conditions under which flux may diminish at large longitudinal distances from the shock origin.
Using automatic detection of discrete features alongside Juno-UVS and in-situ data, this study demonstrates that magnetodisc scattering primarily drives electron precipitation in Jupiter's ultraviolet aurora and classifies injection signatures into dawn-storm and non-dawn-storm types, while suggesting that outer emission arcs are broadened sequences of these signatures.
This paper utilizes ColdSIM hydrodynamical simulations to provide a comprehensive census of baryon phases, depletion times, and stellar return fractions in early galaxies, revealing that the warm gas phase dominates post-reionization and that stellar return fractions are significantly lower than previously assumed.
This paper reviews the 2024 Mother's Day superstorm, utilizing multi-source observations to qualitatively demonstrate how intense space weather disturbances generated strong geoelectric fields and significant geomagnetically induced currents, with a specific focus on their impacts on the New Zealand power grid.
This paper proposes that torsional Alfvén oscillations driven by firehose instability in a laboratory coronal arch experiment cause the rapid reallocation of plasma particles, resulting in the observed cylindrical stratification of the plasma.
This study utilizes a data-constrained, resistive magnetohydrodynamic simulation to demonstrate that a non-force-free initial magnetic field, characterized by a Lorentz force imbalance, can spontaneously trigger the formation and subsequent eruption of a flux rope in active region NOAA 12241 without requiring pre-existing structures or photospheric driving motions.
This study utilizes two-dimensional pseudospectral simulations of the modified nonlinear Schrödinger–magnetosonic system to demonstrate that broadband sub-Alfvénic kinetic Alfvén wave turbulence under plasma sheet boundary layer conditions self-organizes into coherent, filamentary density cavities while exhibiting inertial-range spectral suppression driven by moderate Reynolds number constraints rather than wave physics alone.
