1. Imprints of quantum gravity in the cosmic microwave background / Calmet, Xavier ; Edholm, James ; Kuntz, IberĂȘ
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. [...]

2. Cosmological perturbations in generalised dark Lagrangians / Edholm, James ; Pearson, Jonathan
We describe a new method to parameterise dark energy theories including massive gravity, elastic dark energy and tensor-metric theories. [...]

3. Generalised boundary terms for higher derivative theories of gravity / Teimouri, Ali ; Talaganis, Spyridon ; Edholm, James ; Mazumdar, Anupam
In this paper we wish to find the corresponding Gibbons-Hawking-York term for the most general quadratic in curvature gravity by using Coframe slicing within the Arnowitt-Deser-Misner (ADM) decomposition of spacetime in four dimensions. [...]
