摘要：

Core-collapse Supernovae (SN) correspond to the death of massive stars, and are among the most energetic events in the universe. During their collapse, stars emit most of their energy in the form of neutrinos in a short burst. These particles allow us to directly access processes happening inside the stellar nucleus. A particularly interesting process to detect these astrophysical neutrinos is the coherent elastic neutrino-nucleus scattering (CE nu VS). This process is characterized by a very high cross-section and detected signals in the keV range. The RES-NOVA experiment aims to measure these neutrinos using CE nu VS through a revolutionary approach: an array of cryogenic detectors. To satisfy experimental requirements, RES-NOVA intends to use PbWO4 4 crystals as absorbers operated at temperatures of the order of a few mK. Lead, on top of maximizing the CE nu VS cross-section, will also be of archaeological origins to guarantee an extremely low background in the region of interest. These features will allow RES-NOVA to play an important complementary role in the detection of the next galactic supernova through an excellent energy resolution and high sensitivity to all neutrino flavors.
