COSMOS2020: Exploring the dawn of quenching for massive galaxies at 3 < z < 5 with a new colour selection method

We select and characterise a sample of massive (log(M_{*}/M_{\odot})>10.6) quiescent galaxies (QGs) at 3<z<5 in the latest COSMOS2020 catalogue. QGs are selected using a new rest-frame colour selection method, based on their probability of belonging to the quiescent group defined by a Gaussian Mixture Model (GMM) trained on rest-frame colours...
