Title: The classical evolution of binary black hole systems in scalar-tensor theories

Abstract: In this talk I will discuss recent work on numerically solving for the binary black hole dynamics of black holes in Einstein scalar Gauss-Bonnet (ESGB) gravity. This modified gravity theory can be motivated by effective field theory reasoning, and admits scalarized black hole solutions. These two facts make it a promising theory to constrain using binary black hole, gravitational wave observations. I will discuss how recent advances in mathematical relativity--in particular, the development of the "modified harmonic formulation"--have opened up the possibility of constructing fully nonlinear solutions to the equations of motion of ESGB gravity (in addition to a class of scalar-tensor modified theories known as "Horndeski" theories).
This talk will mostly be based on the preprint: 2011.03547
