This talk reviews recent progress on the modelling ofBNSMs using simulations in numerical general relativity. In the first part, I will discuss predictions for the complete<br \/>(inspiral-merger-postmerger) gravitational-wave spectrum and their application in gravitational-wave astronomy. In the second part, I will discuss merger remnants and mass ejecta, the mechanisms behind<br \/>kilonova light. Finally, I will discuss the application of these results\u00a0to the analyses of multimessenger events.<\/p>\n<p>\u00a0<\/p>\n<p>Pagina indico: <a class=\"\" href=\"https:\/\/agenda.infn.it\/event\/34718\/\">https:\/\/agenda.infn.it\/event\/34718\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract:\u00a0Binary neutron star mergers (BNSM) are cosmic collisions of compact stars associated with powerful gravitational-wave and electromagnetic astronomical transients.
