The 4D Einstein-Gauss-Bonnet theory of gravity: a review
Fernandes, PGS; Carrilho, P; Clifton, T; Mulryne, DJ (2022) -
Black Holes in the Scalar-Tensor Formulation of 4D Einstein-Gauss-Bonnet Gravity: Uniqueness of Solutions, and a New Candidate for Dark Matter
Fernandes, PGS; Carrilho, P; Clifton, T; Mulryne, DJ (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 ... -
Derivation of regularized field equations for the Einstein-Gauss-Bonnet theory in four dimensions
Fernandes, PGS; Carrilho, P; Clifton, T; Mulryne, DJ (2020-07-06) -
Dissecting the growth of the power spectrum for primordial black holes
Carrilho, P; Malik, KA; Mulryne, DJ (2019-11-26) -
Evolution of fNL to the adiabatic limit
Elliston, J; Mulryne, DJ; Seery, D; Tavakol, RWe study inflationary perturbations in multiple-field models, for which zeta typically evolves until all isocurvature modes decay--the "adiabatic limit". We use numerical methods to explore the sensitivity of the nonlinear ... -
Exploring the small mass limit of stationary black holes in theories with Gauss-Bonnet terms
Fernandes, PGS; Mulryne, DJ; Delgado, JFM (2022) -
Generating the cosmic microwave background power asymmetry with g(NL)
Kenton, Z; Mulryne, DJ; Thomas, S (2015-07-06) -
Multi-field inflation with large scalar fluctuations: non-Gaussianity and perturbativity
Iacconi, L; Mulryne, DJ (IOP Publishing, 2023-09-01)Recently multi-field inflation models that can produce large scalar fluctuations on small scales have drawn a lot of attention, primarily because they could lead to primordial black hole production and generation of large ... -
A new approach and code for spinning black holes in modified gravity
Fernandes, PGS; Mulryne, DJ (IOP Publishing Ltd, 2023)We discuss and implement a spectral method approach to computing stationary and axisymmetric black hole solutions and their properties in modified theories of gravity. The resulting code is written in the Julia language ... -
Nonperturbative delta N formalism
Imrith, SV; Mulryne, DJ; Rajantie, A (2018-08-14) -
Numerically evaluating the bispectrum in curved field-space - with PyTransport 2.0
