Cosmological impact of watching the universe expand in real time

Catarina M. J. Marques

Despite the recent progress, many enigmas remain in cosmology. Notable among these is the fact that about 95% of the contents of the universe is in two forms (known as dark matter and dark energy) which so far have not been directly detected. New observational tools are needed to characterize this dark side of the universe. One promising such tool is known as the redshift drift, which will for the first time allow us to watch the universe expand in real time. I will drescribe the impact of redshift drift measurements by the ELT (together with low-redshift supernova data) in specific classes of dark energy models.
