... break galaxies at z ≈ 6-5 in the Hubble Ultra Deep Field (HUDF), six of which have spectroscopic confirmation. At these redshifts, IRAC samples rest-frame optical light in the range 0.5-0.8 μm, where the effects of dust extinction are smaller and the sensitivity to light from evolved stars is greater than at shorter, rest-frame ultraviolet wavelengths observable from the ground or with the Hubble Space Telescope. As such, it provides useful constraints ...

... of seven luminous early-type galaxies in the Hubble Ultra Deep Field (UDF) with spectroscopic redshifts between 1.39 and 2.47, and to KAB < 23. Using the BzK selection criterion, we have preselected a set of objects over the UDF, which fulfill the photometric conditions for being passively evolving galaxies at z > 1.4. Low-resolution spectra of these objects have been extracted from the Hubble Space Telescope (HST) ACS grism data taken over ...
