We report on searches for neutrinos and antineutrinos from astrophysical sources performed with the Borexino detector at the Laboratori Nazionali del Gran Sasso in Italy. Electron antineutrinos ($\bar{\nu}_e$) are detected in an organic liquid scintillator through the inverse $\beta$-decay reaction. In the present work we set model-independent uppe...

... of 0.1 MeV, from 3.5 to 5 MeV in increments of 0.5 MeV, and for E ν > 5 MeV in 1.0 MeV steps. In order to maximize the signal to background ratio, the lower integration limits T th from Eq. 29 was optimized for different neutrino energies considering the shape of the spectrum decreasing with energy (Fig. 7). The three blue lines indicated in Fig. 7 with indices 1, 2, and 3 show the thresholds of electron energies T th , for which E ν was set to (1.5, 3.5) MeV, (4.0, 5.0) MeV, and (6.0, 15.0) MeV intervals, ...

The Deep Underground Neutrino Experiment (DUNE), a 40-kton underground liquid argon time projection chamber experiment, will be sensitive to the electron-neutrino flavor component of the burst of neutrinos expected from the next Galactic core-collapse supernova. Such an observation will bring unique insight into the astrophysics of core collapse as...
