Abstract
The aim of these notes is to provide a brief reviewof the topic of neutrino astronomy and in particular of neutrinos from core collapse supernovae. They are addressed to a curious reader, beginning to work in a multidisciplinary area that involves experimental neutrino physics, astrophysics, nuclear physics and particle physics phenomenology. After an introduction to the methods and goals of neutrinos astronomy, we focus on core collapse supernovae, as (one of ) the most promising astrophysical source of neutrinos. The first part is organized almost as a tale, the last part is a bit more technical.We discuss the impact of flavor oscillations on the supernova neutrino signal ( ¼ the change of perspective due to recent achievements) and consider one specific example of signal in detail. This shows that effects of oscillations are important, but astrophysical uncertainties should be thought as an essential systematics for a correct interpretation of future experimental data. Three appendices corroborate the text with further details and some basics on flavor oscillations; but no attempt at a complete bibliographical survey is made (in practice, we selected a fewreferences that we believe are useful for a “modern” introduction to the subject and suggest the use of public databases for papers [e.g. SPIRES database http://www-spires.slac.stanford.edu/spires/hep/; NASA/ESO database http://esoads.eso.org/ abstract service.html] and for experiments [see SPIRES in previous entry and the PaNAGIC site at http://www.lngs. infn.it/] for more complete information).Pubblicazioni consigliate
