Title: Simulating and Interpreting the Multimessenger Picture of Neutron Star Mergers

Abstract: Neutron stars are among the most compact objects in the Universe, and their
collisions rank among the most energetic events observed. The groundbreaking
multimessenger detection of gravitational waves and electromagnetic signals
from such events has revolutionized astronomy, providing profound insights
into fundamental physics. The correct interpretation of multimessenger data,
including gravitational waves and electromagnetic counterparts, requires
accurate theoretical predictions that can be cross-correlated with
observations. These models can be constructed by combining ab initio
numerical-relativity simulations with derived analytical knowledge. Finally,
an efficient Bayesian framework for multimessenger analysis is indispensable
for extracting meaningful information from observational data. We will
discuss how numerical-relativity simulations and multimessenger data
analysis go hand in hand to provide valuable insights into neutron star mergers and
fundamental physics principles.
