Abstract:
We study the relationships between galaxy environments and galaxy
properties related to disk (re)growth, considering two highly complete
samples that are approximately baryonic mass limited into the
high-mass dwarf galaxy regime, the Environmental COntext (ECO) catalog
(data release herein) and the B-semester region of the REsolved
Spectroscopy Of a Local VolumE (RESOLVE) survey. We quantify galaxy
environments using both group identification and smoothed galaxy
density field methods. We use by-eye and quantitative morphological
classifications plus atomic gas content measurements and estimates. We
find that blue early-type (E/S0) galaxies, gas-dominated galaxies, and
UV-bright disk host galaxies all become distinctly more common below
group halo mass ∼1011.5M☉, implying that this low group halo
mass regime may be a preferred regime for significant disk growth
activity. We also find that blue early-type and blue late-type
galaxies inhabit environments of similar group halo mass at fixed
baryonic mass, consistent with a scenario in which blue early-types
can regrow late-type disks. In fact, we find that the only significant
difference in the typical group halo mass inhabited by different
galaxy classes is for satellite galaxies with different colors, where
at fixed baryonic mass red early- and late-types have higher typical
group halo masses than blue early- and late-types. More generally, we
argue that the traditional morphology-environment relation (i.e., that
denser environments tend to have more early-types) can be largely
attributed to the morphology-galaxy mass relation for centrals and the
color-environment relation for satellites.
Description:
The ECO catalog represents a cross match between sources with measured
redshifts found in the UZC (Updated Zwicky Catalog, Falco et al. 1999,
J/PASP/111/438), SDSS (including data releases 6, 7, and 8; see II/294
and V/139), HyperLEDA (VII/237), RESOLVE (S. J. Kannappan et al. 2015,
in preparation), GAMA (Driver et al. 2011, J/MNRAS/413/971), 2dF
(Colless et al. 2001, VII/250), and 6dF (Jones et al. 2009, VII/259)
catalogs with a 15" matching radius on sky. See section 2.1.

Note (1): The colors and stellar masses were derived from a SED fitting
procedure as described in section 3.2.
Note (2): Morphology flag as follows:
E = early;
L = late;
- = the radius measurement(s) have failed and do not allow the
quantitative morphology cut to be applied.
Note (3): Morphology classification source flag as follows:
1 = quantitative cut;
2 = by eye from Lintott et al. (2011, J/MNRAS/410/166).
Note (4): Smoothed on 1 Mpc/h scale including corrections for finger of
God effects as described in section 3.6.2.
Note (5): ECO+G membership flag as follows:
1 = source belongs to the sample;

Note (6): H I source flag as follows:
1 = photometric gas estimate as described in section 3.7;
2 = gas measurement from the ALFALFA α.40
catalog (Haynes et al. 2011, J/AJ/142/170).
Note (7): That accounts for redshift catalog incompleteness.
Note (8): That counts for incompleteness due to boundary effects.
