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…
