Query: Neutrino Physics and Astronomy with MACRO   MACRO experiment operated in the Gran Sasso underground laboratory. Neutrino
events collected by this detector are used in order to study the atmospheric
neutrino flux. Different measurements in different energy samples are in full
agreement and show evidence of neutrino oscillation phenomenon. Also the search
for neutrino astrophysical sources is reported.
