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 demonstrates that in super-Alfvénic plane shear flows, large-scale velocity shear suppresses magnetohydrodynamic turbulence imbalance through linear non-modal dynamics, driving initially imbalanced systems toward a balanced state of counter-propagating Alfvén waves.
This paper presents a new analytical approach using the chief spacecraft's Cartesian coordinates to describe four-spacecraft formations on elliptic Kepler orbits, demonstrating that the formation's volume can be expressed as a time-dependent polynomial to facilitate mission planning for testing modified gravity theories.
This study presents the first multipoint analysis of MHD turbulence in the October 2024 extreme solar storm using four L1 spacecraft, revealing significant spatial variability, differing turbulence maturity, and strong anisotropies across ICME regions that underscore the critical role of internal processes and azimuthal structure in space weather impacts.
This paper presents a theoretical calculation of the low-frequency antenna resistance and shot noise to correct previous erroneous estimates from Parker Solar Probe data, demonstrating how this resistance influences receiver gain and plasma measurements.
This study demonstrates that real-time geomagnetic storm predictions with significantly improved lead times can be achieved using far-upstream solar wind observations from Solar Orbiter, validating the potential of dedicated upstream missions to enhance space weather forecasting despite challenges in CME propagation modeling.
This paper analytically demonstrates that a distant intermediate-mass black hole cannot be the cause of the observed jet precession in M87* by deriving general Newtonian quadrupolar orbital perturbations and showing that the required parameters fall within excluded regions of the parameter space.
This paper identifies 14 Solar Energetic Particle (SEP) events exhibiting "inverse velocity arrival" (IVA) features, where medium-energy particles arrive before both lower and higher-energy ones, and analyzes how factors like shock acceleration and transport conditions influence this unique arrival profile to advance understanding of SEP dynamics in the inner heliosphere.
During the May 2025 SWPT exercise, the physics-based SOFIE model demonstrated its operational viability by successfully simulating solar energetic particle events in significantly less than real time, achieving a 4-day forecast in 5 hours through optimized grid configurations and collaborative feedback.
This study presents a fully observational-data-driven magnetohydrodynamic simulation of a coronal mass ejection from active region AR 13663 that successfully reproduces its multi-stage kinematic evolution and achieves a one-minute time lag between observed and simulated flare peaks, thereby validating the model's potential for predicting CME onset and elucidating the roles of torus instability, overlying magnetic tension, and magnetic reconnection in the eruption process.
This paper utilizes the GRAPES-3 muon telescope to monitor how variations in the interplanetary magnetic field and upper atmospheric temperature modulate the flux, spectrum, and angular distribution of Galactic Cosmic Rays, particularly those below 30 GeV/nuc affected by solar phenomena.
