We find that z ∼ 1.6 Ultra-Massive Passively Evolving Galaxies (UMPEGs), which have K s (AB) < 19.75 (stellar masses of M > ∼ 10 11.4 M and mean = 10 11.5 M), cluster more strongly than any other known galaxy population at high redshift. Comparing their correlation length, r 0 = 29.77 ± 2.75 h −1 Mpc, with the clustering of dark matter halos in the Millennium XXL N-body simulation suggests that these z ∼ 1.6 UMPEGs reside in dark matter halos of mass M h ∼ 10 14.1 h −1 M. Such very massive z ∼ 1.6 halos are associated with the ancestors of z ∼ 0 massive galaxy clusters such as the Virgo and Coma clusters. Given their extreme stellar masses and lack of companions with comparable mass, we surmise that these UMPEGs could be the already-quenched central massive galaxies of their (proto)clusters. We conclude that with only a modest amount of further growth in their stellar mass, z ∼ 1.6 UMPEGs could be the progenitors of some of the massive central galaxies of present-day massive galaxy clusters observed to be already very massive and quiescent near the peak epoch of the cosmic star formation. %G English %2 https://cnrs.hal.science/hal-03100541/document %2 https://cnrs.hal.science/hal-03100541/file/2002.12891.pdf %L hal-03100541 %U https://cnrs.hal.science/hal-03100541 %~ INSU %~ CNRS %~ UNIV-AMU %~ CNES %~ LAM %~ OSU-INSTITUT-PYTHEAS
