Modeling black hole binaries in scalar-tensor theories of gravity

Parallel session talk Astroparticle and Gravitational Waves T01: Astroparticle and Gravitational Waves


Justin Ripley (DAMPT, University of Cambridge)


I will discuss a new formulation of the Einstein equations and scalar tensor theories of gravity--the modified generalized harmonic (MGH) formulation--that allows for the stable, well-posed evolution of black holes in a wide variety of scalar-tensor theories. I will discuss recent progress in numerically modeling binary black hole evolution, and scalar+gravitational wave emission, in the scalar-tensor theory Einstein scalar Gauss-Bonnet gravity.
