Abstract:
We present imaging and spectroscopy of Abell 1689 (z=0.183) from the
Gemini multi-object spectrograph (GMOS) on the Gemini North telescope
and the Advanced Camera for Surveys (ACS) on the Hubble Space
Telescope (HST). We measure integrated photometry from the GMOS g' and
r' images (for 531 galaxies) and surface photometry from the HSTF625W
image (for 43 galaxies) as well as velocities and velocity dispersions
from the GMOS spectra (for 71 galaxies). We construct the Kormendy,
Faber-Jackson and colour-magnitude relations for early-type galaxies
in Abell 1689 using these data and compare them to those of the Coma
cluster.
Description:
The g'-band images have a plate scale of 0.1454 arcsec/pix (2x2 binning)
while the r'-band images have a plate scale of 0.0727 arcsec/pix (no
binning).
