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…

Atmospheric neutrino oscillation analysis with neutron tagging and an expanded fiducial volume in Super-Kamiokande I-V

Kamiokande Collaboration, T. Wester, K. Abe +233

We present a measurement of neutrino oscillation parameters with the Super-Kamiokande detector using atmospheric neutrinos from the complete pure-water SK I-V (April 1996-July 2020…
