Gamma-Ray Bursts: The Energy Monsters of the Universe
GalaxiesGamma-Ray Bursts(GRBs) are the most violent and energetic astrophysical phenomena, which I dare call “the Energy Monsters of the Universe”. Indeed, they show an enormous emitted isotropic energy ranging from ∼3 × 1046 erg (GRB 170817A) to ∼1055 erg (GRB ...

, 1999 Core collapse supernovae are dominated by energy transport from neutrinos. Therefore, some supernova properties could depend on symetries and features of the standard model weak interactions. The cross section for neutrino capture is larger than that for

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Maven: a multimodal foundation model for supernova science
Machine Learning: Science and TechnologyA common setting in astronomy is the availability of a small number of high-quality observations, and larger amounts of either lower-quality observations or synthetic data from simplified models.

Constraining the Initial Mass Function via Stellar Transients
UniverseThe stellar initial mass function (IMF) represents a fundamental quantity in astrophysics and cosmology describing the mass distribution of stars from low mass all the way up to massive and very massive stars. It is intimately linked to a wide variety of

Ejection of Supernova-Enriched Gas From Dwarf Disk Galaxies
, 2004 We examine the efficiency with which supernova-enriched gas may be ejected from dwarf disk galaxies, using a methodology previously employed to study the self-enrichment efficiency of dwarf spheroidal systems.

Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Oxychlorine Species on Mars: A Review
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

A Very-High-Energy Gamma-Ray View of the Transient Sky
UniverseThe development of the latest generation of Imaging Atmospheric Cherenkov Telescopes (IACTs) over recent decades has led to the discovery of new extreme astrophysical phenomena in the very-high-energy (VHE, E > 100 GeV) gamma-ray regime.

Clinical and Translational Science, Volume 18, Issue 12, December 2025.ABSTRACT The onset of the global COVID‐19 pandemic created an urgent need for therapeutic monoclonal antibody (mAb) development, while the rapid mutation of the SARS‐CoV‐2 virus and emergence of new variants presented a moving target for validation of efficacy. Since it is virtually impossible to conduct randomized controlled trials in the context of a
