Proca theory of four-dimensional regularized Gauss-Bonnet gravity and black holes with primary hair
Christos Charmousis, Pedro G. S. Fernandes, Mokhtar Hassaine
We introduce a novel, well-defined four-dimensional regularized Gauss-Bonnet theory of gravity by applying a dimensional regularization procedure. The resulting theory is a vector-…
Neutron stars and the cosmological constant problem
Giulia Ventagli, Pedro G. S. Fernandes, Andrea Maselli +2
Phase transitions can play an important role in the cosmological constant problem, allowing the underlying vacuum energy, and therefore the value of the cosmological constant, to c…
Spinning Black Holes with Axion Hair
Clare Burrage, Pedro G. S. Fernandes, Richard Brito +1
In this work we construct and analyse non-perturbative stationary and axially-symmetric black hole solutions in General Relativity coupled to an electromagnetic and an axion field.…
Rotating black holes in semiclassical gravity
Pedro G. S. Fernandes
We present analytic stationary and axially-symmetric black hole solutions to the semiclassical Einstein equations that are sourced by the trace anomaly. We also find that the same…
A new approach and code for spinning black holes in modified gravity
Pedro G. S. Fernandes, David J. Mulryne
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 resultin…
Exploring the Small Mass Limit of Stationary Black Holes in Theories with Gauss-Bonnet Terms
Pedro G. S. Fernandes, David J. Mulryne, Jorge F. M. Delgado
In this work we examine the small mass limit of black holes, with and without spin, in theories where a scalar field is non-minimally coupled to a Gauss-Bonnet term. First, we prov…
