Hubble Cycle 18 Proposal Selection

One pure-parallel program will use WFC3’s unique power for slitless spectroscopy to measure cosmic star formation across its peak epoch. Grism spectroscopy in deep and shallow fields will detect a sample of 2,000–3,000 emission-line galaxies in the unexplored redshift region around z = 2–3 and search Ly-α emitters at z > 5.5. A second pure-parallel program aims to search for Lyman-break galaxies at z ≈ 6−8. As the survey fields are random and completely uncorrelated, the number counts will be little affected by biases caused by statistical fluctuations. Hence, we will be able to obtain the best constraint yet on the bright-end of the luminosity function in that redshift range.

Two Legacy AR programs were recommended: one will perform a complete and consistent recalibration of all raw NICMOS polarimetric, science-imaging data in the MAST archive. The goal is to enable science deferred or previously unachieved. This program will create high-level, analysis-quality data sets with quantitative error estimates, which will be entered into the MAST for public dissemination. The second AR program will create a comprehensive, uniformly processed, well documented, and searchable collection of solar-system data obtained with WFPC2. The “planet pipeline” will populate the image headers with information unique to planetary data, and produce a science-ready collection of data.
