Space Telescope Science Institute Archive
Description:
An archive of stellar photometry for galaxies within 3.5 Mpc, excluding Local Group galaxies, based on primary and parallel wide-filter UV and optical observations taken with HST ACS/WFC or WFPC2.The sample includes all observations taken through Dec. 2008, as well as observations
taken as part of Cycle 16 Supplemental GO programs 11986 and 11987. This release includes the ANGST targets within 3.5 Mpc; these observations
have been rereduced using updated CTE corrections and zeropoints. Galaxies with 3.5 < D <= 5 Mpc will be included in a later release.
Cluster Lensing And Supernova survey with Hubble (CLASH)

Description:
By observing 25 massive galaxy clusters with HST's new panchromatic imaging capabilities (Wide-field Camera 3, WFC3, and the Advanced Camera for Surveys, ACS), CLASH will accomplish its four primary science goals:
- Map, with unprecedented accuracy, the distribution of dark matter in galaxy clusters using strong and
weak gravitational lensing;
- Detect Type Ia supernovae out to redshift z ~ 2, allowing us to test the constancy of dark energy's
repulsive force over time and look for any evolutionary effects in the supernovae themselves;
- Detect and characterize some of the most distant galaxies yet discovered at z > 7 (when the Universe
was younger than 800 million years old - or less than 6% of its current age);
- Study the internal structure and evolution of the galaxies in and behind these clusters.
