Overview
Core model: Binary Neutron Star Mergers
Binary neutron star mergers combine gravitational-wave physics, dense nuclear matter, gamma-ray bursts, kilonovae, and heavy-element nucleosynthesis. Unlike typical binary black hole mergers, they can produce rich electromagnetic counterparts because neutron-star matter is disrupted and ejected.
