Scalar-tensor cosmologies without screening
Johannes Noller, Luca Santoni, Enrico Trincherini +1
Scalar-tensor theories are frequently only consistent with fifth force constraints in the presence of a screening mechanism, namely in order to suppress an otherwise unacceptably l…
Black Hole Hair from Scalar Dark Matter
Lam Hui, Daniel Kabat, Xinyu Li +2
We show that a black hole surrounded by scalar dark matter develops scalar hair. This is the generalization of a phenomenon pointed out by Jacobson, that a minimally coupled scalar…
Stable wormholes in scalar-tensor theories
Gabriele Franciolini, Lam Hui, Riccardo Penco +2
We reconsider the issue of whether scalar-tensor theories can admit stable wormhole configurations supported by a non-trivial radial profile for the scalar field. Using a recently…
Effective Field Theory of Black Hole Quasinormal Modes in Scalar-Tensor Theories
Gabriele Franciolini, Lam Hui, Riccardo Penco +2
The final ringdown phase in a coalescence process is a valuable laboratory to test General Relativity and potentially constrain additional degrees of freedom in the gravitational s…
Behind Horndeski: Structurally Robust Higher Derivative EFTs
Luca Santoni, Enrico Trincherini, Leonardo G. Trombetta
Higher derivative scalar interactions can give rise to interesting cosmological scenarios. We present a complete classification of such operators that can yield sizeable effects wi…
The Effective Theory of Shift-Symmetric Cosmologies
Bernardo Finelli, Garrett Goon, Enrico Pajer +1
A shift symmetry is a ubiquitous ingredient in inflationary models, both in effective constructions and in UV-finite embeddings such as string theory. It has also been proposed to…
