Description
Following its successful launch in July 2023 and the start of its scientific survey in February 2024, Euclid has become the first stage-IV photometric survey in operations. In addition to its photometric observations, Euclid is also conducting a spectroscopic survey, which allows us to add even more probes to a combined analysis from Euclid data alone. In this talk I will present the forecasts for a combined analysis at the end of the mission, focusing in particular on how combining multiple probes helps break parameter degeneracies and leads to tighter constraints on dark matter and dark energy. I will conclude by outlining current efforts toward a combined analysis with Euclid's first data release.
