Search for Diffuse Supernova Neutrino Background with 956.2 days of Super-Kamiokande Gadolinium Dataset

K. Abe, S. Abe, Y. Asaoka +245

We report the search result for the Diffuse Supernova Neutrino Background (DSNB) in neutrino energies beyond 9.3~MeV in the gadolinium-loaded Super-Kamiokande (SK) detector with $2…

First Associated Neutrino Search for a Failed Supernova Candidate with Super-Kamiokande

F. Nakanishi, K. Abe, S. Abe +243

In 2024, a failed supernova candidate, M31-2014-DS1, was reported in the Andromeda galaxy (M31), located at a distance of approximately 770 kpc. In this paper, we search for neutri…
