Description
Galaxy clusters provide a powerful way to study how galaxies evolve. At redshifts up to $z\sim1$, dense regions like clusters tend to host massive quenched galaxies, while isolated galaxies remain more active. However, this trend is less understood at higher redshifts, where some cluster cores still show strong star-formation. When do these changes appears?
In this work, we aim to establish the basis for combining Spitzer and Euclid observations to extend the detection of (proto)clusters candidates at redshifts $z>1.3$. To that end, we use Euclid photometry from the Q1 release and our Spitzer photometry and densities to identify extreme Spitzer overdense regions that host large numbers of passive galaxies.
