Core-collapse supernovae emit high neutrino flux after core bounce. In this environment, the neutrino self-interaction is dominant, and the flavor conversions are induced. These affect observed neutrino spectra on the Earth.
We have ever assumed that emitted neutrinos are free-streaming. However, some of neutrinos experience a direction-changing scattering with nuclei and these...

Neutrino and gravitational wave are indispensable messengers of core-collapse supernovae. Those messengers have important information on how the supernovae are initiated.
Helped by recent development of the simulation technique, we can provide the prediction on the gravitational waveforms and neutrino light curves as well as the neutrino spectrum.
In addition to the normal non-rotating...

A new era of the gravitational-wave astronomy has recently begun with multi-messenger observations. There are some theoretical predictions that binary neutron-star mergers emit neutrinos with energies similar to those of supernova burst neutrinos. Ton-scale liquid-xenon detectors for direct dark matter searches also have the potential to observe galactic supernova neutrino via coherent elastic...

Core-Collapse Supernovae (CCSN) are expected to release the $99\%$ of their energy through MeV neutrinos and a network of detectors is operative to look for these events. However, when the source distance increases and/or the average energy of emitted neutrinos decreases, the signal statistics drop and the identification of these low statistic astrophysical bursts could be challenging. In a...

Paleo-detectors are a proposed experimental technique in which one would search for traces of recoiling nuclei in minerals up to $1 \mathrm{\,Gyr}$ old. Even reading out a relatively small target sample ($100 \mathrm{\,g}$), would therefore allow one to search for very rare events thanks to the large exposure, $\epsilon \sim 100 \mathrm{\,g\,Gyr} = 105 \mathrm{\,t\,yr}$. I will show how...
