This one-week TH-Institute (June 9-13, 2025) aims to bring together leading experts in nuclear physics, astrophysics, and particle physics to address the key questions surrounding the equation of state (EOS) of neutron star (NS) matter and its impact on multi messenger astronomy and new physics searches.
The EOS of neutron stars is crucial to understanding several astrophysical phenomena, from supernova explosions and neutrino emissions to gravitational wave signals from NS mergers. By examining the EOS and its interplay with standard model (SM) and beyond-standard model (BSM) physics, this event seeks to address questions like: What are the uncertainties in EOS modeling, and how can they be minimized to yield robust predictions? How do different EOSs affect GW signals and NS cooling mechanisms? How much different EOS impact constraints on new motivated particles, such as the QCD axion? What role does QCD EOS play in the formation of primordial black holes, and how can observations of NS mergers constrain new physics?
The TH-Institute will thus cover a range of topics, including:
- Theoretical modeling of the EOS of NS matter and its observational implications
- Neutrino emissions from young and old neutron stars, and their role in SN explosions
- Gravitational wave signals from NS mergers and their sensitivity to the EOS
- New physics searches in astrophysical environments, with a focus on axions, neutrinos, and gravitational waves
This TH Institute is supported by UNDARK and is funded through the Widening participation and spreading excellence programme (project number 101159929)".
