They are now able to follow the entire evolution from CC through bounce, neutrino-triggered shock revival, and shock breakout at the stellar surface to the electromagnetic SN outburst and the subsequent SN remnant phase. Thus they provide general support for the neutrino-driven explosion mechanism by reproducing observed SN energies, neutron star (NS) kicks, and diagnostically relevant radioactive isotope yields. They also allow prediction of neutrino and gravitational wave signals for many seconds of proto-NS cooling, confirm correlations between explosion and progenitor or remnant properties already expected from previous spherically symmetric (one-dimensional) and two-dimensional models, and carve out various scenarios for stellar-mass black hole (BH) formation. Despite these successes, it is currently unclear which stars explode or form BHs because different modeling approaches disagree and suggest the possible importance of the three-dimensional nature of the progenitors and of magnetic fields. The role of neutrino flavor conversion in SN cores needs to be better understood, the nuclear equation of state (including potential phase transitions) implies major uncertainties, the SN 1987A neutrino measurements raise new puzzles, and tracing a possible correlation of NS spins and kicks requires still more refined SN simulations.","PeriodicalId":8090,"journal":{"name":"Annual Review of Nuclear and Particle Science","volume":"48 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This shielding and high intensity are crucial for accurately measuring very-low-cross-section nuclear reactions essential to understanding astrophysical processes, such as the synthesis of heavy elements in stars from neutron sources and CNO cycle leakage. The manuscript also covers technological achievements, including advancements in ion sources, accelerators, detectors, and targets used in the JUNA experiment. The physics results from these experiments provide valuable data for key reactions, such as neutron source reactions and radiative capture reactions, as well as for the production of heavy elements in early stars.

While early studies were speculative, modern research is based on advanced observations, theory, and modeling. This review examines supernova explosions, γ-ray bursts (GRBs), and kilonova outbursts, which are major sources of ionizing radiation in galaxies. This radiation can harm Earth-like biospheres by destroying stratospheric ozone, increasing exposure to solar ultraviolet, and producing cosmic-ray muons that penetrate belowground and underwater. Using recent work, we calculate rates for nearby explosions based on distance from the Earth and ionizing radiation dose. Over the Earth's history, core-collapse supernova cosmic rays, γ-rays from Type Ia supernovae, X-rays from Type IIn supernovae, and γ-rays from long GRBs have likely caused significant biosphere damage. However, short GRBs and kilonovae are less concerning.
