Dark high-z galaxies unveiled by Euclid and JWST

Abstract:

In this presentation I will briefly discuss how the synergy between Euclid and JWST will be able to detect a population of galaxies almost invisible by HST and even by Spitzer. Such sources lie in a broad redshift range (i.e. 3<z<13)  and are thought to be dominated by massive and obscured objects. In this context, I will highlight recent findings on the most distant galaxies by Webb, and in particular I will report our  investigation of the deep survey in the SMACS0723 cluster, analysing NIRCam and MIRI images and other ongoing efforts from our team. I will also introduce how Euclid will complement the optically dark side of star formation with larger statistics compared to JWST.
