Search for Diffuse Supernova Neutrino Background in the Full KamLAND Dataset with Neural-Network-Based Event Classification

D. Chernyak, T. Eda, M. Eizuka +63

We report a search for the diffuse supernova neutrino background (DSNB) with the KamLAND detector, targeting electron antineutrinos via inverse beta decay in the neutrino energy ra…

Constraints on Fermionic Dark Matter Absorption from Radiochemical Solar-Neutrino Measurements

K. Ishidoshiro, K. Tachibana

We reinterpret classic radiochemical solar-neutrino measurements as ``rate meters'' for additional, non-negative capture-like contributions induced by fermionic dark matter absorpt…

Development of an early warning method incorporating pre-supernova neutrino light curves

Keita Saito, Minori Eizuka, Zhuojun Hu +9

Massive stars () emit neutrinos known as pre-supernova (pre-SN) neutrinos through thermal and nuclear interactions for cooling the stellar core during the fina…

Limits on the Low-Energy Electron Antineutrino Flux from the Brightest GRB of All Time

T. Araki, S. Chauhan, K. Chiba +69

The electron antinuetrino flux limits are presented for the brightest gamma-ray burst (GRB) of all time, GRB221009A, over a range of 1.8-200 MeV using the Kamioka Liquid Scintillat…
