Abstract
Neutrinos, as neutral and weakly interacting particles, play a crucial role in the field of multi-messenger astronomy. This thesis presents a comprehensive study of neutrino emission from various multi-messenger sources, from supernovae to the galactic disk. Two works will be discussed about the expected neutrino flux on Earth from a selected catalog of galactic sources and from a recent supernova, SN2023ixf, exploded in the nearby galaxy M101. In the second part of this thesis, a focus is given to the connection between neutrinos and gravitational waves, two complementary messengers that can provide insights into high-energy astrophysical processes. Preliminary results from a follow-up search of neutrinos in coincidence with the gravitational waves detected during the first period of O4 run using Super-Kamiokande data will be presented. Although no excess of events in coincidence with any gravitational wave has been observed, this has been used to constraint the expected flux of neutrino from these sources. One of the key contributions of this work is the development of an online pipeline for the Super-Kamiokande experiment designed to search for neutrino counterparts to gravitational wave detections. By leveraging realtime data from gravitational wave observatories, the pipeline enables rapid identification and correlation of potential neutrino signals, facilitating timely follow-up observations and enhancing the potential for multi-messenger discoveries. Prospects of neutrino astronomy with the future Hyper-Kamiokande will be also presented.
