Black-hole binary inspiral and merger in scalar tensor theory of gravity

If you have a question about this talk, please contact Helvi Witek .

This talk presents numerical simulations of an inspiraling black-hole binary in scalar tensor theory. The no-hair theorem is overcome in this setup through a scalar field gradient and choosing the orbital plane of the binary to be oriented along the gradient direction. The interaction of the black holes with the scalar field give rise to a radiative scalar dipole which oscillates at twice the orbital frequency.
