Euclid’s Sensitivity to Neutrino Parameters
The European Space Agency launched its newest mission in July 2023: $\textit{Euclid}$, which is designed to create the largest galaxy clustering and weak gravitational lensing survey to date. The complementarity of wide imaging and spectroscopy will provide excellent sensitivity to the history of structure formation, and hence to physics that affects that history. Here we present the latest forecasts of how \euclid's main cosmological probes will be able to constrain parameters from neutrino physics. Specifically we focus on the summed mass of neutrino species $\sum m_\nu$, as well as the effective number of additional relativistic species $\Delta N_\mathrm{eff}$. We show how the forthcoming \euclid data should lead to unprecedented sensitivity for these parameters, and together with data from future cosmic microwave background experiments, could enable a detection of the neutrino mass scale.
