ESO-ESA JOINT 2020 SCIENCE WORKSHOP: NEW SCIENCE IN THE MULTI-MESSENGER ERA

Multi-messenger astronomy - the combination of electromagnetic light with gravitational waves or neutrinos - has come of age. The detection of gravitational waves and a kilonova from a merging neutron star binary, and the identification of a flaring blazar in coincidence with a high energy neutrino mark the beginning of an era where the detections of sources beyond the electromagnetic spectrum will become increasingly common. The facilities of both ESO and ESA are central to efforts to identify the counterparts of sources initially located by either gravitational wave or neutrino observatories, and have made pivotal contributions to these first steps into multi-messenger astronomy. This workshop will celebrate these contributions, summarize the results gathered during the third LIGO/VIRGO observing run, and explore the long term possibilities enabled by LISA, E-ELT, Athena and more.
