To name just a few, these include a census of the merging compact object\u00a0 opulations, the sources of the heaviest elements in the Universe, the properties of matter at extreme densities and temperatures, the sources of gamma-ray bursts and potential modifications of Einstein&#8217;s theory of General Relativity.<br \/>\nWith the availability of a broad spectrum of\u00a0 observational information comes an increasing demand on the realism of the theoretical modelling of neutron star mergers, both in terms of including physical processes and in terms of spanning large length and time scales. In this talk I will provide an overview over our current understanding of these extreme-physics events.<\/li>\n<li><strong>Tuesday 21 April 2026 at 10:15 in A315 and using Zoom:\u00a0<span data-olk-copy-source=\"MessageBody\"> Antonino Salvino Midiri (University of Geneva)<\/span> Onsite Cosmo Seminar<br \/>\n<\/strong><em>TBA<br \/>\nAbstract:\u00a0<\/em>TBA<\/li>\n<li><strong>Thursday 21 May 2026 at 10:15 in A315 and using Zoom: Michal Heller (Ghent)<br \/>\n<\/strong><em>TBA<br \/>\nAbstract: <\/em>TBA<\/li>\n<li><strong>Thursday 6 June 2026 at 10:15 in A315 and using Zoom: Andrea Olzi (Paris)<\/strong><br \/>\n<em>TBA<\/em><br \/>\n<em>Abstract:<\/em> TBA<\/li>\n<li><strong>Tuesday 11 August 2026 at 10:15 in A315 and using Zoom: Christophe Royon (CMS)<br \/>\n<\/strong><em>TBA<br \/>\nAbstract: <\/em>TBA<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><i>Hopefully the up to\u00a0<b>50 min + 10 min discussion long\u00a0<\/b>seminar\/colloquium will be understandable to a wide audience.<br \/>\nContacts: Keijo Kajantie (keijo kajantie at helsinki fi) [ HIP seminar],<br \/>\nTushar Gupta\u00a0 (tushar.gupta at helsinki fi) [<a href=\"http:\/\/www.hip.fi\/cosmoseminars\" target=\"_blank\" rel=\"noreferrer noopener\">cosmo seminar<\/a>]<\/i><\/p>\n<p><i><b>Other related seminars<\/b><\/i><\/p>\n<p><i>Friday 10-12 seminar series in D114:<a href=\"https:\/\/wiki.helsinki.fi\/xwiki\/bin\/view\/Astrophysics\/Astrophysics%20seminar\" target=\"_blank\" rel=\"noopener\">Astrophysics seminar<\/a><\/i><i><br \/>\nMathematical Physics\u00a0<a href=\"https:\/\/www.helsinki.fi\/en\/researchgroups\/mathematical-physics\/seminars-and-workshops\" target=\"_blank\" rel=\"noreferrer noopener\">Seminar and Workshop series<\/a>\u00a0Wed 14-16 in Exactum C123.<br \/>\nInstituteQ <a href=\"https:\/\/instituteq.fi\/news-events\/\" target=\"_blank\" rel=\"noopener\">Events and Seminars<\/a><br \/>\n<\/i><\/p>\n<p><i><b>\u00a0<\/b><\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>DEPARTMENT OF PHYSICS \/ HIP JOINT COLLOQUIA \/ SEMINARS 2026 Thursday 2 April 2026 at 9:30 in E204 and using Zoom: Stephan Rosswog (Hamburg)\u00a0 \u00a0Note unusual time and place!
