Description
An explosion of a galactic Supernova is a unique neutrino source: detecting the neutrinos from deep inside the star will help us understand both the physics of the core collapse and properties of the neutrino themselves. If a SN neutrino burst arrived at Earth today or in the near future, it would be detected by a variety of ton to kiloton scale neutrino detectors based on different technologies and target media. One could significantly improve the precision of determining the neutrino spectra parameters such as the mean energy and spectral index by combining the analysis of the possible explosion in multiple next generation neutrino experiments. By applying this analysis on the time evolution of the SN neutrino spectra one could fit it and obtain parametrisation and estimation its astrophysical parameters. In this contribution it is shown what one could achieve by doing a simultaneous fit of the energy spectra of JUNO, DUNE and IceCube-like detectors assuming a common flavour-dependent neutrino signal.
