Multi-Messenger Astronomy

Modern astrophysics utilizes data from a wide variety of channels extending beyond the conventional optical, radio and X-ray observations. Technological developments have augmented electromagnetic (EW) observations with data from cosmic ray detectors, neutrino detectors and recently from gravitational wave (GW) observatories - together forming the core of multi-messenger astronomy. Each 'messenger' carries complementary information about various physical processes occurring in an astrophysical source. Combining data from all these channels makes it possible to piece together a more detailed understanding of sources than any single channel can. In this article I discuss multi-messenger astronomy with emphasis on joint EM and GW studies.
