J/ApJ/824/124 Galaxy stellar and baryonic mass functions (Eckert+, 2016) ================================================================================ RESOLVE and ECO: the halo mass-dependent shape of galaxy stellar and baryonic mass functions. Eckert K.D., Kannappan S.J., Stark D.V., Moffett A.J., Berlind A.A., Norris M.A. =2016ApJ...824..124E (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, masses ; Models ; Surveys Keywords: galaxies: luminosity function, mass function; methods: statistical; surveys 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 M_bary_~10^9.1^M_{sun}_, probing the gas-rich dwarf regime below M_bary_~10^10^M_{sun}_. The second, ECO, covers a ~40x larger volume (containing RESOLVE-A) and is complete to M_bary_~10^9.4^M_{sun}_. 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 M_star_~10^10^M_{sun}_ that has been described in prior work. However, the BMF fills in this feature and rises as a straight power law below ~10^10^M_{sun}_, 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<10^13.5^M_{sun}_ 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; 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 ~52100Mpc^3^ 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.

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. -------------------------------------------------------------------------------- History: From electronic version of the journal ================================================================================ (End) Prepared by [AAS], Emmanuelle Perret [CDS] 18-Aug-2016
