Title: The multi-messenger picture of merging neutron stars

Abstract:
With the detection of the binary neutron star merger GW170817, a new era 
of multi-messenger astronomy started. GW170817 demonstrated that neutron 
star mergers are ideal laboratories for constraining the equation of 
state of cold supranuclear matter, to study the central engines of short 
GRBs, to understand the origin and production of heavy elements, and to 
measure the expansion rate of the Universe. We discuss how the last 
milliseconds before and after the merger can be investigated with full 
3D numerical relativity simulations. We present results from 
state-of-the-art numerical relativity simulations covering large areas 
of the binary neutron star parameter space and we explain how these 
simulations help to develop gravitational wave and electromagnetic 
models. These models allow us to constrain the unknown equation of state 
of cold supranuclear matter and in the future might even be helpful to 
determine the dark matter content in our Universe. I will conclude with 
a short review of the first months of the ongoing observing run of the 
LIGO and Virgo gravitational wave detectors with respect to binary 
neutron star candidates.
