Search for low-energy neutrinos from astrophysical sources with Borexino

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 (ν¯ e) are detected in an organic liquid scintillator through the inverse β-decay
reaction. In the present work we set model-independent upper limits in the energy range 1.8–
16.8 MeV on neutrino fluxes from unknown sources that improve our previous results, on
average, by a factor 2.5. Using the same data set, we first obtain experimental constraints on …
