Telescope Cycle 11 Archival Research Proposal The WFPC 2 Archival Parallels
نویسنده
چکیده
We propose to process and combine with state-of-the-art tools the majority of the WFPC2 images obtained as part of Archival Pure Parallel Program, consisting of observations of over 3,000 random pointings primarily in the wide WFPC2 UBV I filters. We will produce combined and cosmic-ray cleaned images, as well as object catalogs, for over 2,000 of these pointings. We will use these data to address a wide range of science topics: measuring the cosmic shear on scales from 20′′ to 2′, discovering ∼ 50 starforming galaxies at z ∼ 4, finding optical counterparts to AGNs in wide-area radio and X-ray catalogs, improving the determination of the scale length of the Galactic disk, and studying stellar populations down to ∼ 1M for about 50 separate lines of sight in the LMC. The same data will be available to the astronomical community for a wide variety of other investigations, thus helping realize the legacy of WFPC2 parallel images.

Interactive, Incremental Scheduling for Virtual Telescopes in Education
The Telescopes in Education (TIE) project, which began in 1992, provides remote access for students to control large observatory telescopes in real time. TIE began with a single telescope, and with manual evaluation and scheduling of student requests. With the sucess of TIE, 20 or more additional telescopes are expected to come on line. With proportionally more student requests, we anticipate t...
