Abstract:
We measure optical colors for the bulges of 312 disk galaxies from the
Carnegie-Irvine Galaxy Survey and convert their previously available
R-band structural parameters to stellar-mass parameters. We also
measure their average stellar-mass surface density in the central 1kpc
(Σ1). Comparing the mass-based Kormendy relation with the
original one based on flux, we find that the majority of the
classifications into classical and pseudo bulges, as well as their
overall statistical properties, remain essentially unchanged. While
the bulge-type classifications of the Kormendy relation are robust
against stellar population effects, the mass-based classification
criteria do produce better agreement between bulge structural
properties and their stellar populations. Moreover, the mass-based
Kormendy relation reveals a population of ultradense bulges akin to
high-z compact early-type galaxies, which are otherwise hidden in the
original Kormendy relation. These bulges are probably relics of
spheroids assembled in the early universe, although for some we cannot
rule out some contribution from secular growth. We confirm previous
studies that Σ1 correlates well with bulge surface densities.
Description:
Our sample, introduced in Gao+ (2019, J/ApJS/244/34 and
2020, J/ApJS/247/20), is a subset of the Carnegie-Irvine Galaxy Survey
(CGS; Ho+ 2011, J/ApJS/197/21), which comprises bright (BT≤12.9mag)
galaxies in the Southern Hemisphere without any selection on
morphology, size, or environment. High-quality images in B, V, R, and
I, along with isophotal parameters, were presented in
Li+ (2011, J/ApJS/197/22).
