We have been carrying out a systematic survey of the star formation and ISM properties in the host galaxies of z~6 quasars using millimeter dust continuum and molecular CO emission. In this survey, we recently discovered the first z~6 quasar-starburst merger system: radio-loud quasar CFHQS J1429+5447 (z=6.2) is detected as a bright 3.4 mJy source in millimeter continuum; high resolution EVLA imaging of CO(2-1) transition reveals two distinct peaks separated by 1.2" (6.9 kpc), and ~50 km/s in velocity space, strongly suggesting that this is a merging system with two intense star forming components, only one of which is in the active quasar phase. We propose deep HST WFC3/F105W, F140W observations to confirm the merger nature, and measure the size, morphology, UV-based star formation rate, and constrain the UV continuum slope of both the quasar host galaxy and its merging companion galaxy. Comparison of our HST and mm/CO observations with detailed cosmological simulations of high-redshift quasar formation will place this unique system in the evolutionary sequence of SMBH/galaxy coevolution, and test models of quasar formation. The proposed observation of CFHQS J1429+5447 also provides an important test case for the future high-z quasar host galaxy imaging with HST/JWST and ALMA. ------------------------------------------------------------------------------------ Observations Description ------------------------ The observations include 5-orbit observations of an CFHQS z=6.2 quasars with WFC3/IR F105W and F140W, and 1-orbit observation of a nearby star to measure the PSF with WFC3/IR F105W and F140W. For the observations of the science target, we plan to do the 3-orbits observation with F140W first. Then if possible, please hold the observation for about 10~20 days to let us check the data and decide if we want to continue to do F105W or use the remaining 2 orbits in F140W to improve the S/N.
