Massive z ~ 1.3 evolved galaxies revealed

We present the results of TNG near-IR low resolution spectroscopy of two (S7F5254 and S7F5_45) sources belonging to a complete sample of 15 EROs with K' <18 and R-K' >5 selected from the MUNICS Survey. Both the spectra show a sharp drop in the continuum which can be ascribed only to the Balmer break. This places them at 1.2 ≈3 .5 and zf>≈2 for the two EROs respectively.
