Scientific paper

We outline a continuing program to study galaxy evolution through the investigation of galaxy morphology as a function of lookback time. The development of disks and bulges, the role of mergers, interactions, and other environmental influences, are expected to be visible over the range 0 < z < 1 as judged by the spectrophotometric evolution already observed over this redshift range. We propose in Cycle 2 to continue our efforts by imaging with the Wide Field Camera two additional fields containing rich clusters of galaxies at z = 0.5 for which extensive photometry and spectroscopy already exist. The fields include a range of environments, from the dense cores of clusters to isolated field galaxies. These data will be used primarily to classify images according to traditional morphological categories and will be used, within the constraints implied by deconvolution techniques, to measure surface brightness distributions and bulge-to-disk ratios. A brief description is given of how the data are applicable to specific questions, like the cause of enhanced starburst activity found for high-z galaxies. NOTE: The portion of the program contained in this observing program ID 5707 consists of the unfinished portion of the CL1446 observations left over from Cycle 2 and is now being done with WFPC2 instead of WFPC-I.
