Constraining Scalar-Tensor Modified Gravity with Gravitational Waves and Large Scale Structure Surveys
(IOP Publishing, 2021-01)
The first multi-messenger gravitational wave event has had a transformative affect on the space of modified gravity models. In this paper we study the enhanced tests of gravity that are possible with a future set of ...
Black Holes in the Scalar-Tensor Formulation of 4D Einstein-Gauss-Bonnet Gravity: Uniqueness of Solutions, and a New Candidate for Dark Matter
(American Physical Society, 2021)
In this work we study static black holes in the regularized 4D Einstein-Gauss-Bonnet theory of gravity; a shift-symmetric scalar-tensor theory that belongs to the Horndeski class. This theory features a simple black hole ...
Multi-Scale Perturbation Theory II: Solutions and Leading-Order Bispectrum in the $Λ$CDM Universe
(IOP Publishing, 2021-08-20)
Two-parameter perturbation theory (2PPT) is a framework designed to include the relativistic gravitational effects of small-scale nonlinear structures on the large-scale properties of the Universe. In this paper we use the ...
