The Role of Magnetic Fields in AGN Activity and Feedback
, 2018 Active galactic nuclei (AGNs), the luminous, compact core regions of galaxies where accretion occurs onto supermassive black holes, can dramatically influence their entire host galaxy evolution by a process referred to as AGN feedback. Energy feedback to

The dynamic role of magnetic fields in galaxy evolution [PDF]
, 2014 Magnetic fields are present in a variety of astrophysical environments, where they can affect the motions and structure of matter. Observations of magnetic fields in the Milky Way show that magnetic fields are an important force acting on gas in the ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Martian Proton Albedo as Signature of Near‐Surface Water
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Towards AMR Simulations of Galaxy Formation [PDF]
, 2010 Numerical simulations present a fundamental building block of our modern theoretical understanding of the Universe. As such the work in this thesis is primarily concerned with understanding fundamental differences that lie between the different ...

Solar Energetic Particle Prediction in the Inner Heliosphere Using Deep Learning and PSP/IS⊙IS Data
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Solar events, such as coronal mass ejections and solar flares, accelerate large numbers of energetic charged particles, producing solar energetic particle (SEP) events that can harm astronauts, damage satellites, and potentially damage infrastructure on Earth.

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes
Space Weather, Volume 24, Issue 6, June 2026.Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.
