With input from my contact scientists and the TTRB, I switched to 3 WFC3 observations and was able to obtain sufficient exposure time in a single orbit. -1678220429 ----- Attempting Submission 1 (Thu Oct 03 19:36:30 GMT 2013) ----- The radio galaxy 3C 220.3 (z=0.685) is lensing a submm galaxy (SMG) at z=2.221 housing an AGN. This unique system allows accurate estimates of both stellar and dark mass in the luminous radio galaxy. In addition, the lensing magnification of 7 offers an unprecedented view of the interaction between star formation and AGN feedback in a luminous, dusty galaxy at the peak epoch of cosmic star formation. Our previous 10ks Chandra observation shows X-ray emission throughout the system, including the SMG, but with too few counts to identify the origin(s). We propose deeper Chandra and HST observations to (1) locate the X-ray sources, measure the X-ray properties and independently estimate the bolometric luminosities of both AGN (2) better map the offset between the SMG's UV and dust emission. 3-color imaging of 3C220.3 Default false false false false false SUPPORTED GALAXY GRAVITATIONAL LENS HIGH REDSHIFT GALAXY LOBE RADIO GALAXY This object was generated by the targetselector and retrieved from the SIMBAD database.

CASM was run in Phase II mode. By using WFC3 for all 3 observations, I was able to get them all into a single orbit. S/N seems fine according to ETC. F814W has time: 1338 instead of planned 1800s, but S/N is still >100 for all 3 pieces of the source.
