The Effects of Environment on the Evolution of the Galaxy Stellar Mass Function

Abstract: We study the effects of galaxy environment on the evolution of the stellar-mass function (SMF) over 0.2 < z < 2.0 using the FourStar Galaxy Evolution (ZFOURGE) survey and NEWFIRM Medium-Band Survey (NMBS) down to the stellar-mass completeness limit, log M * /M ⊙ > 9.0 (9.5) at z = 1.0 (2.0). We compare the SMFs for quiescent and star-forming galaxies in the highest and lowest environments using a density estimator based on the distance to the galaxies' third-nearest neighbors. For star-forming galaxies, at all… Show more

“…Balogh et al (2016) find that the environmental quenching efficiency decreases with stellar mass and becomes inefficient at log M * < 9.5. Their results are supported by Papovich et al (2018), who study the effect of the environment in shaping the evolution of the stellar mass function in the redshift range 0.2 < z < 2.0, and find that the evolution of the stellar mass function of Environmental quenching efficiency as a function of halo mass at different redshifts (different colors), for galaxies in two stellar mass ranges (different panels). The efficiency of environmental quenching does not depend strongly on the halo mass for low mass galaxies, while it strongly depends on halo mass for more massive galaxies.…”

“…Balogh et al (2016) analyse galaxies in groups and clusters at 0.8 < z < 1.2 from the GCLASS and GEEC2 surveys and find that env (called conversion fraction in their paper) is nearly independent of stellar mass for galaxies more massive than log M * ∼ 10.3, but it decreases at lower stellar mass, becoming consistent with zero at log M * ∼ 9.5. The inefficiency of the environment in quenching low mass galaxies has been pointed out also by Papovich et al (2018). As introduced above, these authors study the evolution of the stellar mass functions of quiescent and star forming galaxies in a wide redshift range and argue that a mass-invariant env in the low mass end, below log M * ∼ 9.5, should end up in a steeper slope of the stellar mass function of quiescent galaxies than observed.…”

“…We also find that the environmental quenching efficiency is not independent of the stellar mass and it clearly increases Figure 6. Environmental dependence of SFR and sSFR for a mass-complete sample of galaxies (Table 3) with stellar mass, although this rise is weaker compared to the mass quenching efficiency (see also Lin et al 2014;Papovich et al 2018). At z < 1.2, the environmental quenching is dominant for low mass galaxies (M 10 10 M ).…”

“…However, there is strong evolution in the number density of lower mass quiescent galaxies, similar to that seen in other studies (e.g., Tomczak et al 2014;Moutard et al 2016). This build up in low-mass quiescent galaxies is expected to occur from the quenching of satellites (see discussion in Kawinwanichakij et al 2017;Papovich et al 2018).…”
