Outer-planet scattering can gently tilt an inner planetary system
Pierre Gratia, Daniel Fabrycky
Chaotic dynamics are expected during and after planet formation, and a leading mechanism to explain large eccentricities of gas giant exoplanets is planet-planet gravitational scat…

Hidden Sector Dark Matter Models for the Galactic Center Gamma-Ray Excess
Asher Berlin, Pierre Gratia, Dan Hooper +1
The gamma-ray excess observed from the Galactic Center can be interpreted as dark matter particles annihilating into Standard Model fermions with a cross section near that expected…

Self-accelerating Massive Gravity: Exact solutions for any isotropic matter distribution
Pierre Gratia, Wayne Hu, Mark Wyman
We present an exact solution to the equations of massive gravity that displays cosmological constant-like behavior for any spherically symmetric distribution of matter, including a…
