The SNO+ Collaboration reports the first evidence of reactor antineutrinos in a Cherenkov detector. The nearest nuclear reactors are located 240~km away in Ontario, Canada. This analysis uses events with energies lower than in any previous analysis w

EstrellaNueva: an open-source software to study the interactions and detection of neutrinos emitted by supernovae

Autor: González-Reina, O. I., Rumleskie, J., Vázquez-Jáuregui, E.

Supernovae emit large fluxes of neutrinos which can be detected by detectors on Earth. Future tonne-scale detectors will be sensitive to several neutrino interaction channels, with thousands of events expected if a supernova emerges in the galaxy nei
