The ACSGGCT program used the HST ACS/WFC instrument to obtain uniform imaging of 65 of the nearest globular clusters to provide an extensive homogeneous dataset for a broad range of scientific investigations. An overview of the project was published by Sarajedini, A. et al. 2007, "The ACS Survey of Galactic Globular Clusters. I. Overview and Clusters Without Previous Hubble Space Telescope Photometry" AJ, 133, 1658.
Archive of Nearby Galaxies: Reduce, Reuse, Recycle (ANGRRR)
Short Name:
HST.ANGRRR
Date:
22 Jul 2020 22:28:43
Publisher:
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.
The Brightest of Reionizing Galaxies (BoRG) observations were first obtained in HST Cycle 17 in program GO 11700 (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). Data from the HIPPIES program uses the F600LP filter instead of F606W.
Cluster Lensing And Supernova survey with Hubble (CLASH)
Short Name:
HST.CLASH
Date:

Publisher:
Space Telescope Science Institute Archive
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.
Deep Optical Photometry of Six Fields in the Andromeda Galaxy
Short Name:
HST.Andromeda

Publisher:
Space Telescope Science Institute Archive
Description:
Using the Advanced Camera for Surveys on the Hubble Space Telescope, Thomas Brown
(STScI) et al. obtained deep optical images reaching well below the oldest main
sequence turnoff in six fields of the Andromeda Galaxy. The fields fall at four
positions on the southeast minor axis, one position in the giant stellar stream,
and one position on the northeast major axis. These data were obtained as part of
three large observing programs (9453, 10265, 10816) designed to probe the star
formation history of the stellar population in various structures of the galaxy.
Galaxy Halos, Outer disks, Substructure, Thick disks and Star clusters (GHOSTS)
Short Name:
GHOSTS
Date:
22 Jul 2020 21:59:56
Publisher:
Space Telescope Science Institute Archive
Description:
The GHOSTS survey is the largest study to date of the resolved stellar populations in the outskirts of disk galaxies. The sample consists of 14 disk galaxies within 17 Mpc, whose outer disks and halos are imaged with the Hubble Space Telescope Advanced Camera for Surveys (ACS).
GOODS aims to unite extremely deep observations from NASA's Great Observatories, the Spitzer Space Telescope, Hubble, and Chandra, ESA's XMM-Newton, and from the most powerful ground-based facilities, to survey the distant universe to the faintest flux limits across the broadest range of wavelengths. GOODS will survey a total of roughly 320 square arcminutes in two fields centered on the Hubble Deep Field North and the Chandra Deep Field South.
HST ACS Coma cluster (Abell 1656) Treasury Survey (COMA)
Short Name:
HST.COMA

Space Telescope Science Institute Archive
Description:
The HST ACS Coma cluster Treasury survey is a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656).
In January 2005, the Hubble Heritage Team obtained a large 4-color mosaic image of the Whirlpool Galaxy NGC 5194 (M51), and its companion NGC 5195, with the Advanced Camera for Surveys (ACS) onboard the Hubble Space Telescope (HST observing program 10452, PI: Steven V. W. Beckwith). A six-pointing ACS WFC mosaic of the galaxy pair M51 was obtained in four filters: B, V, I, and H-alpha.
The Archival Pure Parallel Project processed and combined about 2,000 WFPC2 images, primarily in the wide UBVI filters, obtained in parallel with other HST instruments. Combined, drizzled, cosmic-ray cleaned images were produced for each pointing. These data can be used 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 1 solar mass for about 25 separate lines of sight in the Magellanic Clouds.
