We present a complete census of candidate nuggets, i.e., dense galaxies likely formed by compaction with intense gas influx, within the volume-limited $z \sim 0$ REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey. These nuggets span all evolutionary stages and 3 orders of magnitude in stellar mass ($M_{*} \sim 10^{8} M_\odot$ to $10^{11} M_\odot$) from the dwarf to the giant regime. We develop selection criteria for our $z\sim0$ nugget candidates based on structure and introduce the use of environmental criteria to eliminate nugget-like objects with suspected non-compaction origins. The resulting $z\sim0$ nuggets follow expectations with respect to structure (i.e., density, size), population frequency, and likely origins. We show that the properties of our nugget census are consistent with permanent quenching above the gas-richness threshold scale (halo mass $M_{halo} \sim 10^{11.4} M_\odot$), cyclic temporary quenching below the threshold scale, and feedback from active galactic nuclei (AGN) assisting in permanent quenching. As predicted in simulations, most nuggets quench within the halo mass range $M_{halo} \sim 10^{11.45} M_\odot$ to $10^{11.9} M_\odot$. We find $\sim 0.29$ dex scatter around the star-forming main sequence for candidate blue nuggets below the threshold scale, which is consistent with temporary quenching as seen in simulations. A transitional population of green nuggets appears above the threshold scale. AGN also become more common in nuggets above this scale, and we see a likely AGN excess in nuggets vs. comparably selected non-nuggets. Our results provide the first observational confirmation of the mass-dependent, AGN-mediated shift from cyclic quenching to halo quenching in nuggets.

Quenching and ram pressure stripping of simulated Milky Way satellite galaxies
我们提出了一套30个宇宙学变焦模拟银河系类宿主星系的本星系群的卫星星系的恒星形成的淬火的预测。御夫座的模拟解决卫星到银河系的经典矮球状星系的光度。我们发现强烈的质量依赖和距离依赖的淬火信号,超过600千秒差距的矮系统只有强烈淬火低于恒星质量的$10^7$ M $_\odot$。冲压压力剥离似乎是占主导地位的淬火机制和50%的淬火系统停止恒星形成内1 Gyr的第一次下降。我们表明,在宿主星系的$R_{200}$半径的系统是由两个人口:(一)第一个落入人口已进入主机晕在过去的几个Gyrs和(ii)人口返回“backsplash”系统,有一个更广泛的互动与主机。后溅星系如果没有通过红移为零的方式返回到宿主星系,则表现出类似于$R_{200}$内部星系的猝灭特性,并且与其他外部系统不同。模拟淬火与恒星质量的趋势有一定的张力与观测,但我们的模拟能够再现淬火时间的范围内,从解决本群矮星系的恒星星族测量。

ALMaQUEST -- IV. The ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) Survey
ALMaQUEST(ALMA-MaNGA QUEnching and STar formation)巡天是一个利用阿塔卡马大型毫米波阵列(ALMA)对46个星系进行空间分辨$^{12}$ CO(1-0)测量的计划,这些星系是从Apache Point Observatory(MaNGA)DR 15光学积分场分光巡天中选出的。ALMaQUEST巡天的目的是研究恒星形成活动对附近星系kpc尺度的冷分子气体含量的依赖性。该样本由跨越范围广泛的特定恒星形成率(sSFR)的星系组成,包括星爆(SB),主序星(MS)和绿谷(GV)星系。在本文中,我们介绍了ALMA观测的样本选择和特征,并展示了空间匹配的恒星星族和气体测量相结合所带来的一些关键结果。考虑到全球(孔径匹配)恒星质量,分子气体质量,和恒星形成率的样品,我们发现,sSFR依赖于恒星形成效率(SFE)和分子气体分数($f_{\rm H_{2}}$),虽然后者的相关性稍弱。此外,sSFR对分子气体含量(SFE或$f_{\rm H_{2}}$)的依赖性强于对原子气体分数或分子-原子气体分数的依赖性,尽管具有小的HI样品尺寸。在kpc尺度上,单个星系内的SFE和$f_{\rm H_{2}}$的变化可以大到1-2 dex,从而表明空间分辨观测的可用性对于了解恒星形成和淬灭过程的细节至关重要。

SDSS-IV MaNGA: The Roles of AGNs and Dynamical Processes in Star Formation Quenching in Nearby Disk Galaxies
我们研究如何在低红移盘星系的恒星形成(SF)淬火积分场光谱。我们选取了131个恒星质量大于$\rm 3\times10^{10}M_\odot$,且具有来自MaNGA DR 13的空间分辨光谱的正面螺旋星系。我们将样本分为四个组的基础上的偏移量的全球特定的恒星形成率(SFR)的恒星形成的主要序列和堆叠的径向配置文件的恒星质量和SFR。通过比较静止盘星系和恒星形成盘星系的堆积轮廓,我们发现,全球SFR的减少是由于在所有半径的SF的抑制,但从中心到外部区域的内部-外部模式的下降更显着。由于全球特定的SFR减少,中央恒星质量,部分盘星系托管恒星酒吧,和活动星系核(AGN,包括LINER和Seyferts)都增加,表明动力学过程和AGN反馈可能是贡献者的内向外淬火的SF在本地宇宙。然而,如果我们只包括Seyferts,或活动星系核与${\rm EW(Hα)>3Å}$,活动星系核的分数增加的趋势与全球sSFR减少消失。因此,如果活动星系核的反馈是有助于淬火,我们怀疑它在低光度活动星系核模式,如更被动的盘星系的大凸起质量的增加所示。
