Abstract:
We present deep HST ACS observations in g475r625i775z850
toward the z=4.1 radio galaxy TN J1338-1942 and its overdensity of >30
spectroscopically confirmed Lyα emitters (LAEs). We select 66
g475 band dropouts to z850,5sigma=27, 6 of which are also LAEs.
Description:
We observed one field with the ACS around the radio galaxy
TN J1338-1942.
