Abstract

Neutrinos, being one of the most abundant particles in the universe, provide crucial information about astronomical objects that are inaccessible by other means. Recently, neutrino detectors have undergone rapid development and gained prominence, as is the case of the IceCube Observatory, a pioneer in this type of detection. Since 2010, IceCube has accumulated significant data on the flux of very high-energy astrophysical neutrinos. In particular, it recently released unprecedented results indicating an excess of neutrinos originating in the galaxy NGC 1068. Such discoveries and events have played an essential role in the field of Multi-messenger Astrophysics, enriching our understanding of the most extreme phenomena in the universe. This project proposes a study of the scientific context of this new line of research, delving into topics in Particle Physics and Astrophysics, in addition to planning a qualitative analysis of the neutrino detection processes at the IceCube Observatory and their relevance to Multi-messenger Astrophysics.
