Brightest of Reionizing Galaxies ("BORG")

The Brightest of Reionizing Galaxies (BoRG) observations were first obtained in HST Cycle 17 in program GO 11700 (PI: Michele Trenti) and continued in Cycle 19 with program GO 12572 (PI: Michele Trenti). BoRG is an ongoing pure-parallel program that obtains WFC3 imaging in four filters (F606W, F098M, F125W, F160W) on random sightlines at high Galactic latitudes (|b| > 30 degrees). BoRG also assimilates data from the similar Hubble Infrared Pure Parallel Imaging Extragalactic Survey (HIPPIES) pure-parallel program (GO 11702; PI: Yan) as well as the coordinated parallel observations acquired as part of the Cosmic Origins Spectrograph (COS) GTO program (GO 11519, 11520, 11524, 11528, 11530, 11533, 11534, 11541, 12024, and 12025).
