Abstract:
We present a photometric analysis of 65 galaxies in the rich cluster
Abell 1689 at z=0.183, using the Hubble Space Telescope Advanced
Camera for Surveys archive images in the rest-frame V band. We perform
two-dimensional multicomponent photometric decomposition of each
galaxy adopting different models of the surface-brightness
distribution. We present an accurate morphological classification for
each of the sample galaxies. For 50 early-type galaxies, we fit both a
de Vaucouleurs law and a Sersic law; S0s are modelled by also
including a disc component described by an exponential law. Bars of
SB0s are described by the profile of a Ferrers ellipsoid. For the 15
spirals, we model a Sersic bulge, exponential disc and, when
required, a Ferrers bar component. We derive the Fundamental Plane
(FP) by fitting 40 early-type galaxies in the sample, using different
surface-brightness distributions. We find that the tightest plane is
that derived by Sersic bulges. We find that bulges of spirals lie on
the same relation. The FP is better defined by the bulges alone rather
than the entire galaxies. Comparison with local samples shows both an
offset and rotation in the FP of Abell 1689.
Description:
In this investigation, we used images from HST ACS. We downloaded the
data, originally obtained for program GO-9289 (PI: H. Ford), from
MAST. The images are from the Wide Field Channel (WFC) with the F625W
filter, which approximates the Sloan Digital Sky Survey (SDSS)-r
filter and is nearly equivalent to rest-frame V band at the redshift
of Abell 1689 (z = 0.183). Our data reduction procedures are described
in Paper I (Houghton et al., 2021, Cat. J/MNRAS/423/256).
We performed a photometric analysis of 65 galaxies, i.e. 54 galaxies
from the spectroscopic sample and 11 from the ancillary sample.
