Plasma Acceleration by Magnetic Tension Forces in the Martian Magnetotail: MAVEN Observations

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Martian magnetotail is a dynamic region where several processes contribute to plasma acceleration. Here, we analyze ∼5 ${\sim} 5$ years of Mars Atmosphere and Volatile EvolutioN (MAVEN) data to evaluate the role of magnetic tension forces in driving plasma acceleration within current sheets in the tail. Based on magnetic field measurements,

Latest results from the PHOBOS experiment

, 2008
Over the past years PHOBOS has continued to analyze the large datasets obtained from the first five runs of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. The two main analysis streams have been pursued.

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1394-1403, November 2025.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

Exploring the Validation Results of the Advanced Solar Particle Events Casting System (ASPECS)

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Solar Energetic Particle (SEP) events can adversely affect space and ground‐based systems. Space weather effects associated with SEP events can impact communication and navigation systems, spacecraft electronics and operations, space power systems, crewed space missions, and commercial aircraft operations.

Modeling the Crustal Magnetic Field of Mars With Physics‐Informed Neural Networks

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Satellites orbiting Mars have measured crustal magnetic fields up to two orders of magnitude stronger than those on Earth. Although Mars currently lacks an active global magnetic field, this magnetization preserves a valuable record of the planet's early dynamo activity and crustal evolution.

On the Impact Origin of Phobos and Deimos I: Thermodynamic and Physical Aspects

, 2017
Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood.
