DESCRIPTION:Speakers: Azamat Saimuha (Государственный ун
 иверситет Дубна)\nNeutrinos emitted during the gravitational
  core collapse supernova are the most direct probe of processes in the ste
 llar interior which are inaccessible to electromagnetic observations. Inte
 rpretation of signals from future flares by\, e.g.\, JUNO\, DUNE\, IceCube
 -Gen2\, KM3NeT\, Baikal-GVD detectors\, requires consideration of a comple
 x set of physical effects [1] including generation of ultra-strong magneti
 c inductions\, nonlinear evolution of neutrino fluxes etc. In this work we
  analyse neutrinos bursts emitted by a protoneutron star at supernova expl
 osion taking into account effects of magnetization and oscillations. The n
 eutrino acceleration near the neutrino sphere due to nuclear scattering ca
 used by the Gamow-Teller neutral current interaction is shown. The effect 
 of oscillations in the outer layers of stars significantly enhances the ha
 rdness of the spectrum of electron antineutrinos. Such an enhancement of t
 he high-energy spectrum component is particularly pronounced for the inver
 ted mass ordering and favorable for ground-based detection of supernova ne
 utrinos. The possibilities of Cherenkov underwater detectors − KM3NeT an
 d Baikal-GVD − for observation of supernova neutrinos and reveling the m
 ass ordering are discussed.\n\nhttps://indico.particle.mephi.ru/event/626/
