Observing Supernova Neutrino Light Curves with Super-Kamiokande.VI. A Practical Data Analysis Technique Considering Realistic Experimental Backgrounds
Fumi Nakanishi, Ken'ichiro Nakazato, Masayuki Harada +9
Neutrinos from supernovae, especially those emitted during the late phase of core collapse, are essential for understanding the final stages of massive star evolution. We have been…
Neutrino Constraints on Black Hole Formation in M31
Yudai Suwa, Ryuichiro Akaho, Yosuke Ashida +9
We investigate neutrino signals associated with black hole formation resulting from the gravitational collapse of massive stars, motivated by the candidate failed supernova M31-201…
Observing Supernova Neutrino Light Curves with Super-Kamiokande. V. Distance Estimation with Neutrinos
Yudai Suwa, Akira Harada, Masamitsu Mori +7
Neutrinos are pivotal signals in multi-messenger observations of supernovae (SNe). Recent advancements in the analysis method of supernova (SN) neutrinos, especially in quantitativ…
Gravitational Collapse of White Dwarfs to Neutron Stars. I. From Initial Conditions to Explosions with Neutrino-radiation Hydrodynamics Simulations
Masamitsu Mori, Ryo Sawada, Yudai Suwa +3
This paper provides collapses of massive, fully convective, and non-rotating white dwarfs (WDs) formed by accretion-induced collapse or merger-induced collapse and the subsequent e…
Observing Supernova Neutrino Light Curves with Super-Kamiokande. IV. Development of SPECIAL BLEND: a New Public Analysis Code for Supernova Neutrinos
Akira Harada, Yudai Suwa, Masayuki Harada +6
Supernova neutrinos are invaluable signals that offer information about the interior of supernovae. Because a nearby supernova can occur at any time, preparing for future supernova…
Search for supernova bursts in Super-Kamiokande IV
Kamiokande collaboration, M. Mori, K. Abe +242
Super-Kamiokande has been searching for neutrino bursts characteristic of core-collapse supernovae continuously, in real time, since the start of operations in 1996. The present wo…
Observing Supernova Neutrino Light Curves with Super-Kamiokande. III. Extraction of Mass and Radius of Neutron Stars from Synthetic Data
Yudai Suwa, Akira Harada, Masayuki Harada +6
Neutrinos are guaranteed to be observable from the next galactic supernova (SN). Optical light and gravitational waves are also observable, but may be difficult to observe if the l…
Diffuse Supernova Neutrino Background Search at Super-Kamiokande
Kamiokande Collaboration, K. Abe, C. Bronner +216
A new search for the diffuse supernova neutrino background (DSNB) flux has been conducted at Super-Kamiokande (SK), with a -ktonday exposure from its fourth…
Observing Supernova Neutrino Light Curves with Super-Kamiokande. II. Impact of the Nuclear Equation of State
Ken'ichiro Nakazato, Fumi Nakanishi, Masayuki Harada +6
The late-time evolution of the neutrino event rate from supernovae is evaluated for Super-Kamiokande using simulated results of proto-neutron star (PNS) cooling. In the present wor…
Search for neutrinos in coincidence with gravitational wave events from the LIGO-Virgo O3a Observing Run with the Super-Kamiokande detector
Kamiokande collaboration, K. Abe, C. Bronner +209
The Super-Kamiokande detector can be used to search for neutrinos in time coincidence with gravitational waves detected by the LIGO-Virgo Collaboration (LVC). Both low-energy ($7-1…
Developing an end-to-end simulation framework of supernova neutrino detection
Masamitsu Mori, Yudai Suwa, Ken'ichiro Nakazato +5
Massive stars can explode as supernovae at the end of their life cycle, releasing neutrinos whose total energy reaches erg. Moreover, neutrinos play key roles in supernov…
Sensitivity of Super-Kamiokande with Gadolinium to Low Energy Anti-neutrinos from Pre-supernova Emission
C. Simpson, K. Abe, C. Bronner +186
Supernova detection is a major objective of the Super-Kamiokande (SK) experiment. In the next stage of SK (SK-Gd), gadolinium (Gd) sulfate will be added to the detector, which will…
Observing Supernova Neutrino Light Curves with Super-Kamiokande: Expected Event Number over 10 s
Yudai Suwa, Kohsuke Sumiyoshi, Ken'ichiro Nakazato +4
Supernova neutrinos are crucially important to probe the final phases of massive star evolution. As is well known from observations of SN1987A, neutrinos provide information on the…
