Morphologies and Spectral Properties of Luminous, Red Galaxies at z ~ 1


I will present the results from two surveys which were aimed to study the detailed morphological and spectral properties of red galaxies at redshift of 1. The sample in these studies were selected using optical/near-IR color (I - K) redder than 4 and are the candidates of galaxies with old stellar population at z > 1. Using the high resolution HST images, we measured the morphological properties of our sample. In addition, we obtained deep optical spectra of the sources in our sample using the Low Resolution Imager and Spectrograph on the keck. I will summarize the implication of our results on the formation and evolution massive galaxies since redshift of 1.
