Abstract:
We present multicomponent decomposition of high-quality R-band images
of 320 disk galaxies from the Carnegie-Irvine Galaxy Survey. In
addition to bulges and disks, we successfully model nuclei, bars, disk
breaks, nuclear/inner lenses, and inner rings. Our modeling strategy
treats nuclear rings and nuclear bars as part of the bulge component,
while other features such as spiral arms, outer lenses, and outer
rings are omitted from the fits because they are not crucial for
accurate bulge measurements. The error budget of bulge parameters
includes the uncertainties from sky-level measurements and model
assumptions. Comparison with multicomponent decomposition from the
Spitzer Survey of Stellar Structure in Galaxies reveals broad
agreement for the majority of the overlapping galaxies, but for a
considerable fraction of galaxies there are significant differences in
bulge parameters caused by different strategies in model construction.
We confirm that on average bulge prominence decreases from early- to
late-type disk galaxies, although the large scatter of bulge-to-total
ratios in each morphological bin limits the application of Hubble type
as an accurate predictor of bulge-to-total ratio. In contrast with
previous studies claiming that barred galaxies host weaker bulges, we
find that barred and unbarred spiral galaxies have similar bulge
prominence.
Description:
The Carnegie-Irvine Galaxy Survey (CGS) sample is defined by
BT≤12.9mag and δ<0°, without any reference to morphology,
size, or environment. Details of the observations and data reduction
are given in Paper I (Ho+ 2011, J/ApJS/197/21) and Paper II
(Li+ 2011, J/ApJS/197/22). All the images for CGS were taken with the
du Pont 2.5m telescope, during the period 2003 February to 2006 June,
spread over 69 nights and nine observing runs.
The majority of the R-band images are of high quality: the median
seeing is 1.01", the median surface brightness depth is
26.4mag/arcsec2, and the field of view of 8.9'x8.9'.
The sample analyzed in this paper is an extension of the sample of S0s
presented in Paper VII (Gao+ 2018, J/ApJ/862/100).
