27. Title: Constraining constant and tomographic coupled dark energy with low- and high-redshift probes

Lisa Goh (CEA/Irfu/DAp/LCS)

We consider coupled dark energy (CDE) cosmologies, where dark matter particles feel a force stronger than gravity, due to the fifth force mediated by a scalar field which plays the role of dark energy. We perform for the first time a tomographic analysis of coupled dark energy, where the coupling strength is parametrised and constrained in different redshift bins. This allows us to verify...
