Making sense of the unexpected in the gravitational-wave sky, SISSA node
GWSky is an ERC Synergy Grant that unites four nodes — SISSA, the Max Planck Institute for Gravitational Physics (AEI) in Potsdam, UCLA, and the Niels Bohr Institute — to build the theoretical framework and analysis tools needed for the coming flood of gravitational-wave observations. This site is the SISSA node.
