These observations are now possible for the first time, as UVIS on WFC3 (coincidentally) provides narrow-band filters at the right wavelengths. Circumstantial evidence (based on NIR, radio/millimeter and molecular gas measurements) suggests that these quasar hosts are undergoing intense ~1000 Msun/yr bursts of star formation over scales of ~5kpc (0.6"). Our program will provide (continuum-subtracted) images of the Lyman Alpha emission in the host which will in turn directly constrain the extent and magnitude of star formation in the host. In the case of the host galaxy of J1148+5251 (z=6.42) the Lyman Alpha emission will be compared to resolved imaging of the molecular gas phase (CO and [CII]) which in turn will yield critical constraints on the structure of the host galaxy and the conditions of the interstellar medium. The observations should also be sensitive enough to reveal potential companion galaxies (if the quasars are residing in major overdensities at these redshifts) and infall signatures in the immediate vicinity of the quasar. The narrow-band filters of UVIS/WFC3 provide the unique opportunity to study host/bulge formation at the end of cosmic reionization (less than 1Gyr after the Big Bang). ------------------------------------------------------------------------------------ Observations Description ------------------------ observing program to obtain narrow band lyman alpha imaging of 2 qso hosts at z~6 using the quad filters on wfc3. for each qso, one narrow band filter will be centred on the lyman alpha emission. a second narrow-band filter will observe the continuum emission. strategy is to observe one line and one continuum image in one orbit. exposure times are long (half orbit) as observations are read-out noise 11640( 6) - 16-Sep-2010 17:05:13 - [ 2] dominated. also, one psf star will be observed in the beginning of visit 1. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- important note: all four visits should be scheduled as closely together in time as possible as psf stability is key to this program. certainly visits 1&2 and visits 3&4 need to be scheduled close in time. if all four visits could be scheduled close in time this would be ideal (psf star will only be observed in visit 1). ------------------------------------------------------------------------------------ 11640( 6) -
