PI: Dr. Belinda J. Wilkes Smithsonian Institution Astrophysical Y Observatory CoI: Dr. Peter D. Barthel Kapteyn Astronomical Institute N CoI: Dr. Martin Haas Ruhr-Universitat Bochum N ------------------------------------------------------------------------------------ Abstract 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. ------------------------------------------------------------------------------------ Observations Description ------------------------ 3-color imaging of 3C220.3 Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ 13506( 2) - 03-Oct-2013 19:47:34 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 3C-220.3 GALAXY, GRAVITATIONAL RA=09H39M23.8600S, J2000 Z = HST 702W 0.0253 mJy LENS, HIGH REDSHIFT DEC=+83D15'25.90" 0.685 GALAXY, LOBE, RADIO GALAXY Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.

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.
