Comparison of Solar Energetic Particle Flux Measurements by CRaTER and GOES

Space Weather, Volume 23, Issue 4, April 2025.
Abstract The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) aboard the Lunar Reconnaissance Orbiter spacecraft has been operating in lunar orbit since 2009. CRaTER data provide a long‐term record of the near‐Moon radiation environment that is relevant to human exploration.

Measurement of Anisotropies in Supernova Remnant Observations and Their Interpretation Using Numerical Models

The Astrophysical Journal
Supernova remnants (SNRs) exhibit varying degrees of anisotropy, which have been extensively modeled using numerical methods. We implement a technique to measure anisotropies in SNRs by calculating power spectra from their high-resolution images. To test

Nowcasting Solar Energetic Particle Events for Mars Missions

Space Weather, Volume 23, Issue 4, April 2025.
Abstract In addition to the omnipresent Galactic Cosmic Rays, sudden Solar Energetic Particle (SEP) events present considerable health hazards for manned space missions. These events not only contribute to an increased long‐term cancer risk, but can, in extreme cases, cause acute radiation syndromes.

Time Evolution of the Synchrotron X-Ray Emission in Kepler’s Supernova Remnant: The Effects of Turbulence and Shock Velocity

The Astrophysical Journal
The maximum energy of electrons in supernova remnant (SNR) shocks is typically limited by radiative losses, where the synchrotron cooling time equals the acceleration time.

SARS‐COV‐2 Pre‐Exposure Prophylaxis With Tixagevimab‐Cilgavimab in Haematological, Immunocompromised Patients in the Omicron Era

European Journal of Haematology, Volume 114, Issue 4, Page 690-699, April 2025.
ABSTRACT Background Pre‐exposure prophylaxis with tixagevimab‐cilgavimab significantly reduced severe COVID‐19 outcomes in high‐risk individuals during the pre‐Omicron era (PROVENT trial). However, efficacy in patients with haematological malignancies (HM) was underreported.
