Follow UsDeep Optical Photometry of Six Fields in the Andromeda Galaxy
|
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 products are fully described in Brown et al. (2009, ApJS, in press). The HLSP includes a preprint of the paper. |
