Event Description

Please Note: This workshop is not open to the general public, but only to active researchers.

Starting with the first detection of gravitational waves (GW) from merging black holes in 2015, GW
detections have led to breakthroughs in cosmology, relativistic astrophysics and multi-messenger
astronomy alike. The coincident detection of electromagnetic counterparts, in particular, has the
potential to provide novel constraints on dense matter and the properties of neutron stars.

At the end of this year, the LIGO-Virgo-KAGRA collaboration is expected to begin their next observing
run (O4). The last observing run gave rise to many exciting GW detections, including the second ever
binary neutron star merger and the first confirmed neutron star-black hole mergers, but saw no new
electromagnetic counterparts. Thanks to new improvements to the detectors, it is highly anticipated
that the new observing run will detect many more neutron star mergers, with up to 2-4
electromagnetic counterparts expected per year. Interpreting this upcoming, new zoo of GW events
with and without EM counterparts – in particular how the features of these events can be related back
to properties of the binary, to the dense-matter equation of state, and to chemical enrichment rates –
requires detailed multi-scale, multi-physics modeling, that touches on many different areas of physics
and astronomy.

This workshop will bring together a wide range of experts working on these topics, ranging from
nuclear physicists, theoretical and observational astrophysicists, as well as simulation experts. By
providing a unique opportunity to connect the various communities, this workshop will provide a
stimulating environment to prepare for the interpretation of the exciting discoveries expected in the
upcoming year.
