The Distinguishability of Interacting Dark Energy from Modified Gravity
Timothy Clemson, Kazuya Koyama
We study the observational viability of coupled quintessence models with their expansion and growth histories matched to modified gravity cosmologies. We find that for a Dvali-Gaba…

Interacting Dark Energy -- constraints and degeneracies
Timothy Clemson, Kazuya Koyama, Gong-Bo Zhao +2
In standard cosmologies, dark energy interacts only gravitationally with dark matter. There could be a non-gravitational interaction in the dark sector, leading to changes in the e…
