The Era of Multi Messenger Astronomy

Abstract

Theoretical and technological developments in the last century paved the way for probing the universe using multiple cosmic messengers. The recent opening up of the previously inaccessible domains of messengers is providing us with a plethora of information that would revolutionize our fundamental understanding of the universe. In this article we explore two new messengers of the universe : Gravitational waves and Neutrinos, their cosmological origins and the methods of detection. Moreover, we explain the current and future observational facilities intended for exploring these aspects.
