Description
The selection of passive galaxies in the early (z>3) Universe is very challenging, and crucial to constrain theoretical modelling of the processes responsible for their rapid assembly and abrupt shut-down of the star formation. I will describe the careful selection method which we developed to single out quiescent galaxies at high z in the CANDELS fields. I will present the resulting sample of 102 candidates at z>3 and show how ALMA archival observations support and confirm their passive nature. Finally, I will discuss the contribution of adaptive optics in the study of early passive galaxies.
