Abstract:

Recent results from the Dark Energy Spectroscopic Instrument has shifted our understanding about dark energy, preferring about 2-3 sigma evidence for evolving dark energy. The phantom crossing of the dark energy equation of state has motivated the search of new cosmological models. In this talk, I will discuss how combinations of data from Rubin Observatory LSST, Simons Observatory and SKAO can assist in better understanding the nature of dark energy and solutions to cosmological tensions. I will present forecasts on Rapid Transition Dark Energy and Early Dark Energy models, and discuss the challenges and systematics in different datasets. Specifically, I will present which combinations to datasets generate best constraints on extended models.
