We develop a method to constrain the level of non-Gaussianity of density perturbations when the 3-point function is of the "equilateral" type. Departures from Gaussianity of this f…

Ghosts in Massive Gravity
Paolo Creminelli, Alberto Nicolis, Michele Papucci +1
In the context of Lorentz-invariant massive gravity we show that classical solutions around heavy sources are plagued by ghost instabilities. The ghost shows up in the effective fi…
