Abstract We propose to use archival ACS data from the GOODS Treasury Program to determine the space density of elliptical galaxies in the field as a function of redshift. Models based on the monolithic collapse scenario and on hierarchical assembly will be compared with the space density vs redshift to determine which theory better describes the formation and evolution of elliptical galaxies. ------------------------------------------------------------------------------------ 9951( 1) - 04/04/03 10:33 - [ 2] Summary Form for Proposal 9951 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Proposal Category AR ------------------------------------------------------------------------------------------------------------------------------------
