Core-collapse supernovae (SN) mark the end of the life of massive stars life (>8 $M_{\odot}$). Such a process leads to the emission of a high-intensity flux of all-flavor (anti-)neutrinos, with $\sim$10$^{58}$ $\nu$ ejected within a time window of $\simeq$10 s. SN-neutrinos carry away a large fraction of the binding energy of the progenitor star, and they are a direct probe of the stellar core. Therefore their detection would provide insights about the many processes happening during the core collapse of the star and the SN explosion.

RES-NOVA aims to deploy the first SN-$\nu$ observatory consisting in an array of cryogenic detectors made from archaeological Pb. The detection channel will be the Coherent Elastic neutrino-Nucleus Scattering (CE$\nu$NS), which provides higher cross section of interactions with respect to other detection mechanisms and also allows to be equally sensitive to all the neutrino flavours emitted during a SN. These features will allow RES-NOVA to deploy a small-scale SN-$\nu$ observatory with high sensitivity to all the (anti-)neutrinos components of a SN exploding within our galaxy.
