Abstract:
We have obtained photometry and spectroscopy of 433 z≤0.08 brightest
cluster galaxies (BCGs) in a full-sky survey of Abell clusters to
construct a BCG sample suitable for probing deviations from the local
Hubble flow. This sample allows us to explore the structural and
photometric properties of BCGs at the present epoch, their location in
their hosting galaxy clusters, and the effects of the cluster
environment on their structure and evolution. We revisit the
Lm-α relation for BCGs, which uses α, the log-slope of
the BCG photometric curve of growth, to predict the metric luminosity
in an aperture with 14.3kpc radius, Lm, for use as a distance
indicator. We measure central stellar velocity dispersions, σ,
of the BCGs.
Description:
Images of the BCGs were obtained in 13 runs between 1989 and 1995
using CCD cameras on the Kitt Peak National Observatory (KPNO) 4m,
KPNO 2.1m, and Cerro Tololo Inter-American Observatory (CTIO) 1.5m
telescopes.We obtained long-slit spectra of all BCG candidates in the
sample over the course of 14 observing runs, spanning a 5yr timeframe,
at NOAO's CTIO and KPNO. The CTIO observations were done primarily
using the Blanco 4m Telescope, except for the first two runs, which
used the 1.5m telescope. All KPNO runs were done using the Goldcam
spectrograph on the 2.1m telescope.
