Black holes with a nonconstant kinetic term in degenerate higher-order scalar tensor theories
Masato Minamitsuji, James Edholm
We investigate static and spherically symmetric black hole (BH) solutions in shift-symmetric quadratic-order degenerate higher-order scalar-tensor (DHOST) theories. We allow a nonc…
Black hole solutions in shift-symmetric degenerate higher-order scalar-tensor theories
Masato Minamitsuji, James Edholm
We show that most classes of shift-symmetric degenerate higher-order scalar-tensor (DHOST) theories which satisfy certain degeneracy conditions are not compatible with the conditio…
Infinite Derivative Gravity: A finite number of predictions
James Edholm
Ghost-free Infinite Derivative Gravity (IDG) is a modified gravity theory which can avoid the singularities predicted by General Relativity. This thesis examines the effect of IDG…
Imprints of Quantum Gravity in the Cosmic Microwave Background
Xavier Calmet, James Edholm, Iberê Kuntz
It has been shown that the spectrum of quantum gravity contains at least two new modes in addition to the massless graviton: a massive spin-0 and a massive spin-2. We calculate the…
Cosmological perturbations in generalised dark Lagrangians
James Edholm, Jonathan Pearson
We describe a new method to parameterise dark energy theories including massive gravity, elastic dark energy and tensor-metric theories. We first examine a framework to describe an…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
