Messengers of the universe

The observation of the solar neutrinos and of a neutrino burst from the supernova explosion 1987A opened a new observation field which in the next years could be complemented with the detection of astrophysical highenergy neutrinos. Neutrino astronomy is a young discipline derived from the fundamental necessity of extending conventional astronomy beyond the usual electro-magnetic messengers. This is a summary of recent results on those new “messengers of the universe”, based on the presentations in Branch IV of the Neutrino Oscillation Workshop 2010 (NOW2010).
