Gravitational wave interactions in models of dark energy
A. Emir Gumrukcuoglu, Kazuya Koyama
We argue that cubic order interactions between two scalar gravitons and one tensor graviton are ubiquitous in models of dark energy where the strong coupling scale is . These…
Unified framework for Early Dark Energy from -attractors
Matteo Braglia, William T. Emond, Fabio Finelli +2
One of the most appealing approaches to ease the Hubble tension is the inclusion of an early dark energy (EDE) component that adds energy to the Universe in a narrow redshift windo…
Stable Cosmology in Generalised Massive Gravity
Michael Kenna-Allison, A. Emir Gumrukcuoglu, Kazuya Koyama
We present a thorough analysis of the cosmological perturbations in Generalised Massive Gravity. This is an extension of de Rham-Gabadadze-Tolley theory where the translation invar…
