Announcement for the next gravity-theory seminar:

*William East *(Perimeter Institute)
Wednesday, Mar 24th, h16:00

*Title*: *Evolving Binary Black Hole Spacetimes Beyond Einstein*

*Abstract*: Gravitational wave observations of black hole and other compact
object mergers have given us an unparalleled way to test our understanding
of gravity, and have already been used to constrain a number of possible
deviations from general relativity. However, despite the success of these
observations, for many alternative theories, it is unclear how to, or even
if one can, obtain a full theoretical prediction of what happens, e.g.,
when two black holes merge. I will discuss some recent progress in this
regard, showing how full, non-perturbative evolutions of Horndeski theories
of gravity can be carried out using a modified harmonic formulation.
Focusing on the particular case of Einstein-scalar-Gauss-Bonnet gravity as
a first application, I will present new results on the dynamics of black
hole scalarization and the mergers of compact objects. These methods can be
used to make gravitational wave predictions in the strong-field regime, as
well as providing a way to benchmark approximate treatments of deviations
from general relativity.
