Abstract:
In this work, we present galaxy stellar and baryonic (stars plus cold
gas) mass functions (SMF and BMF) and their halo mass dependence for
two volume-limited data sets. The first, RESOLVE-B, coincides with the
Stripe 82 footprint and is extremely complete down to baryonic mass
Mbary∼109.1M☉, probing the gas-rich dwarf regime below
Mbary∼1010M☉. The second, ECO, covers a ∼40x larger volume
(containing RESOLVE-A) and is complete to Mbary∼109.4M☉. To
construct the SMF and BMF we implement a new "cross-bin sampling"
technique with Monte Carlo sampling from the full likelihood
distributions of stellar or baryonic mass. Our SMFs exhibit the
"plateau" feature starting below Mstar∼1010M☉ that has been
described in prior work. However, the BMF fills in this feature and
rises as a straight power law below ∼1010M☉, as gas-dominated
galaxies become the majority of the population. Nonetheless, the
low-mass slope of the BMF is not as steep as that of the theoretical
dark matter halo MF. Moreover, we assign group halo masses by
abundance matching, finding that the SMF and BMF, separated into four
physically motivated halo mass regimes, reveal complex structure
underlying the simple shape of the overall MFs. In particular, the
satellite MFs are depressed below the central galaxy MF "humps" in
groups with mass<1013.5M☉ yet rise steeply in clusters. Our
results suggest that satellite destruction and stripping are active
from the point of nascent group formation. We show that the key role
of groups in shaping MFs enables reconstruction of a given survey's
SMF or BMF based on its group halo mass distribution.
Description:
To measure the galaxy stellar and baryonic mass functions (SMF and
BMF), we use two volume-limited data sets, the B-semester subvolume of
the RESOLVE survey, RESOLVE-B (Kannappan & Wei 2008AIPC.1035..163K 2008AIPC.1035..163K;
Kannappan et al. 2016, in preparation), and the ECO catalog (Moffett
et al. 2015, J/ApJ/812/89), which contains the RESOLVE-A subvolume.
RESOLVE is a volume and roughly baryonic mass limited survey of
∼52100Mpc3 of the z∼0 universe. It is smaller but more complete than
ECO and is acquiring new 21cm and optical spectroscopy to conduct a
full mass census of stars, gas, and dark matter.

Note (1): Mass function data values are provided only above the completeness
limit for each data set. A value of 0.0000 signifies that a
particular mass function does not have a value at that mass. The mass
function units are scaled per logM (i.e., per dex) to remove
dependence on the bin size.
