Multi-messenger astrophysics

Multi-messenger astrophysics is a new field that uses information carried by cosmic messengers: photons, cosmic rays, neutrinos and gravitational waves, to observe and understand violent astrophysical phenomena such as neutron star mergers or blazars. Such events are ephemeral and to observe them many instruments at various locations around the world need to be ready to react fast. Large volumes of data in different formats are produced and must to be analysed quickly. These peculiarities of multi-messenger observation campaigns led to the need for a complex cyberinfrastructure, the use of AI technologies and increased international collaboration and coordination.


Multi-messenger astrophysics is an emerging discipline that combines the information from cosmic rays, neutrinos, gravitational waves and photons emitted by cosmic sources. This overview of the field highlights its challenges and exciting opportunities.
