Neutrinos from supernovae

The physics of supernova neutrinos continues to be a puzzle. Insight into the nature of collective oscillations, that were obtained over the past decade, are slowly beginning to reveal a rich phenomenology. One of major issues is the role of symmetry breaking, be it in spatial homogeneity or temporal stationarity. We reported some new results in this specific area and reviewed the progress in the field of supernova neutrinos, in general. (paper)
