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

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.
The Faint Object Camera (FOC) was one of the 4 original axial instruments on the Hubble Space Telescope (HST). FOC is used to make high-resolution observations of faint sources at UV and visible wavel
The Faint Object Spectrograph (FOS) was one of the 4 original axial instruments aboard the Hubble Space Telescope (HST). The FOS was designed to make spectroscopic observations of astrophysical sources from the near ultraviolet to the near infrared (1150 - 8000 Angstroms). The instrument was removed from HST during the Second Servicing Mission in February 1997.
Galaxy Halos, Outer disks, Substructure, Thick disks and Star clusters (GHOSTS)
Short Name:
GHOSTS
Date:

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).
