ADC_Keywords: Galaxies, optical ; Morphology ; Redshifts Keywords: galaxies: evolution - galaxies: fundamental parameters - galaxies: high-redshift - galaxies: structure Abstract: We have conducted the largest systematic search so far for stellar disk truncations in disklike galaxies at intermediate redshift (z<1.1), using the Great Observatories Origins Deep Survey-South (GOODS-S) data from the Hubble Space Telescope ACS. Focusing on type II galaxies (i.e., downbending profiles), we explore whether the position of the break in the rest-frame B-band radial surface brightness profile (a direct estimator of the extent of the disk where most of the massive star formation is taking place) evolves with time. The number of galaxies under analysis (238 of a total of 505) is an order of magnitude larger than in previous studies. For the first time, we probe the evolution of the break radius for a given stellar mass (a parameter well suited to address evolutionary studies). We have explored the distribution of the scale lengths of the disks in the region inside the break and how this parameter relates to the break radius. We also present results of the statistical analysis of profiles of artificial galaxies, to assess the reliability of our results. Description: We have worked with objects present in imaging data from HST ACS observations of the GOODS-South field (Giavalisco et al., 2004, Cat. II/261), which subtends an area in the sky of roughly 170arcmin2. File Summary:

Note (3): From COMBO17 (Wolf et al. 2001A&A...365..681W, 2003A&A...401...73W; see also Cat. II/253). Note (4): The median value of the Pearson's R parameter for the linear fit from where h1 is derived is r1=0.993. Note (5): Profiles are classified in types I = no break apparent (exponential profile fit) II = break or truncation (profile steeper at larger radii, h1>h) III = antitruncation (inner profile steeper, h1<h)
