Crunching, Bouncing, and Cyclical Cosmologies from Dark Sector Interactions
Marcel van der Westhuizen, Amare Abebe
We present new mechanisms that produce either a future Big Crunch turnaround or a past non-singular bounce in flat FLRW cosmologies within general relativity at the background leve…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Interacting dark energy: clarifying the cosmological implications and viability conditions
Marcel A. van der Westhuizen, Amare Abebe
In this study, cosmological models are considered, where dark matter and dark energy are coupled and may exchange energy through non-gravitational interactions with one other. Thes…
