Core-Collapse Supernovae, failed supernovae and quark novae are expected to release an energy of few 1053 ergs through MeV neutrinos and a network of detectors is operative to look online for these events. However, when the source distance increases and/or the average energy of emitted neutrinos decreases, the signal statistics drops and the identification of these low statistic astrophysical bursts could be challenging. In a standard search, neutrino detectors characterise the observed… 
Multimessenger analysis strategy for core-collapse supernova search: gravitational waves and low-energy neutrinos
Core-collapse supernovae are fascinating astrophysical objects for multimessenger studies. Gravitational waves are expected to play an important role in the supernova explosion mechanism.
Joint Analysis Method on Gravitational Waves and Low-Energy Neutrinos to Detect Core-Collapse Supernovae
Core-collapse supernovae produce copious low-energy neutrinos and are also predicted to radiate gravitational waves. These two messengers can give us information regarding the explosion mechanism.


Pinpointing astrophysical bursts of low-energy neutrinos embedded into the noise
We propose a novel method to increase the probability of identifying impulsive astrophysical bursts of low-energy neutrinos. The proposed approach exploits the temporal structure differences between
The search for failed supernovae with the Large Binocular Telescope: confirmation of a disappearing star
We present Hubble Space Telescope imaging confirming the optical disappearance of the failed supernova (SN) candidate identified by Gerke, Kochanek & Stanek. This ∼25 M⊙ red supergiant experienced a
Quark-Nova as Gamma Ray Burst Precursor
We explore the scenario where the core of a neutron star (having experienced a transition to an up and down quark phase) shrinks into the equilibrated quark object after reaching strange quark matter
SNEWS: the SuperNova Early Warning System
This paper provides a technical description of the SuperNova Early Warning System (SNEWS), an international network of experiments with the goal of providing an early warning of a galactic supernova.
