Black-Hole Scattering in Einstein-scalar-Gauss-Bonnet: Numerical Relativity Meets Analytics
Shaun Swain, Tamanna Jain, Llibert Aresté Saló
The study of hyperbolic binary black hole encounters yields an effective probe of the strong field regime of black holes, thus providing an additional channel to test General Relat…

Gravitational scattering of solitonic boson stars: Analytics vs Numerics
Thibault Damour, Tamanna Jain, Ulrich Sperhake
We study the scattering of boson-star binaries, taking into account three effects: point-mass gravitational, tidal, and short-range scalar-field interactions. We compare analytic r…

A Non-linear Massive Gravity Theory of Geometric Origin
Thibault Damour, Tamanna Jain
We study the number of propagating degrees of freedom, at non-linear order, in torsion gravity theories, a class of modified theories of gravity that include a propagating torsion…
