Messengers from the High-Energy Universe

Abstract

By combining observations of a single phenomenon using different related particles, it is possible to achieve a more complete understanding of the properties of the sources; this approach is known as multi-messenger astrophysics. Multi-messenger astrophysics has developed in the beginning of the century using mostly information coming from charged particles and from photons at different wavelengths. In the very recent years simultaneous measurements involving also the detection of neutrinos and gravitational waves have been performed, expanding the horizon of astronomy.
