Abstract

HST is now uniquely capable of measuring the time variation of dark energy (DE) using supernovae (SNe) - and to address the recent surprising low DE density measured at very high redshift by BAO. The MCT survey has shown that field SN rates at z>1 are too low to accomplish this, but it can be done with a search for SNe in massive clusters. Based on the high SN rate found in our ACS-NICMOS SN cluster survey, we propose a cadenced two-cycle SN survey of 10 of the most massive known clusters at z = 1.1 to 1.75. We expect to accurately measure ~30 Type Ia SNe at these redshifts. The exquisite sensitivity of WFC3 ensures that each SN will have the high S/N color measurements necessary to provide the necessary control of the dominant astrophysical systematics so we can measure the density history of DE over the largest possible z range. With this calibration, our SN results at z>1 will be limited by statistical rather than systematic errors. This unique cluster data set will also be used for numerous key cosmology questions: Weak lensing (WL) cluster-masses derived from our imaging will allow the first calibration of the Sunyaev-Zeldovich (SZ)-mass relation at z > 1 at the level of precision required to make SZ derived masses competitive as strong measurements of DE. For the main science goal of this proposal, we can shrink the uncertainty on DE density at z>1 below +/- 0.6 - and be able distinguish the recent BAO low-density result from a cosmological constant at almost 3 sigma. We improve the uncertainty on DE equation of state w at redshifts z > 0.5 by a factor of three using SNe alone, and by combining the SN and WL results, double the DETF Figure of Merit to over 100.
