Binary Black Hole simulations in scalar-Gauss-Bonnet gravity*

A thorough modeling of the strong-field regime in alternative theories of gravity is fundamental for exploiting the full potential of gravitational-wave observations and constraining deviations from General Relativity. This is a challenging task that often requires non-trivial extensions to the well-established Numerical Relativity framework. We present preliminary results on a regularization scheme inspired by the Israel-Stewart technique, developed with the aim of obtaining a well-posed initial value problem in scalar-Gauss-Bonnet effective field theory of gravity.
