Short‐Term Effect of Mars‐Like Radiation on Carbon and Oxygen Isotope Compositions of Carbonates

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The stable isotope composition of carbonates records the environmental formation conditions and can indicate potential biosignatures if formed biologically. Martian meteorite carbonates display unusually high δ13C values, not explained using known terrestrial processes.

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

Simulations of Radiological Dose Quantities in Astronauts During Solar Energetic Particle Events Across Modern Space History

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Solar Particle Events (SPEs) represent one of the most significant hazards to future crewed space missions. Accurate assessment of radiation doses received by astronauts during these events is essential for determining the shielding requirements in spacecraft and off‐planet shelter design.

Astrophysics: The slow death of red galaxies.

Nature, 2015
For most galaxies, the shutdown of star formation was a slow process that took 4 billion years. An analysis of some 27,000 galaxies suggests that 'strangulation' by their environment was the most likely cause.

High-Energy Astrophysics in the 2020s and Beyond [PDF]

, 2019
With each passing decade, we gain new appreciation for the dynamic, connected, and often violent nature of the Universe. This reality necessarily places the study of high-energy processes at the very heart of modern astrophysics.

The Evolution of Galaxies and Their Environment [PDF]

The Third Teton Summer School on Astrophysics discussed the formation of galaxies, star formation in galaxies, galaxies and quasars at high red shift, and the intergalactic and intercluster medium and cooling flows.
