LYMAN BREAK GALAXIES , Ly EMITTERS , AND A RADIO GALAXY IN A PROTOCLUSTER AT z

Abstract

We present deepHSTACS observations in g475r625i775z850 toward the z 1⁄4 4:1 radio galaxy TN J1338 1942 and its overdensity of >30 spectroscopically confirmedLy emitters (LAEs).We select 66 g475 band dropouts to z850;5 1⁄4 27, 6 of which are also LAEs. Although our color-color selection results in a relatively broad redshift range centered on z 1⁄4 4:1, the… (More)
