在z≥3处存在的大量大质量宁静星系种群，挑战了我们对短时间尺度内星系快速增长和猝灭的理解。为了拼凑这一演化谜题，需要更多这些天体的统计样本。用于识别大质量宁静星系的成熟技术在z>3时日益低效且缺乏约束。因此，研究报告称，现有巡天可能漏掉多达70%的z>3宁静星系。在这项工作中，我们提出一种新的经验颜色选择技术，旨在利用JWST NIRCam成像数据选择3≲z≲6处的大质量宁静星系。我们使用由经验约束的星系SED模板，在F277W−F444W对F150W−F277W颜色平面中定义一个区域，以捕获z>3的宁静星系。我们将该颜色选择标准应用于Cosmic Evolution Early Release Science（CEERS，宇宙演化早期发布科学）巡天，识别出44个z≳3宁静星系候选体。这些源中超过一半为新发现，并且平均表现出星暴后星系的比恒星形成率。我们得到3<z<5处的体密度估计n∼1–4×10^-5 Mpc^-3，发现其与CEERS天区类似种群的已有报告高度一致。得益于NIRCam的波长覆盖和灵敏度，该技术为搜寻这些稀有星系的大样本提供了高效工具。
英文摘要：
Substantial populations of massive quiescent galaxies at $z\ge3$ challenge our understanding of rapid galaxy growth and quenching over short timescales. In order to piece together this evolutionary puzzle, more statistical samples of these objects are required. Established techniques for identifying massive quiescent galaxies are increasingly inefficient and unconstrained at $z>3$. As a result, studies report that as much as 70\% of quiescent galaxies at $z>3$ may be missed from existing surveys. In this work, we propose a new empirical color selection technique designed to select massive quiescent galaxies at $3\lesssim z \lesssim 6$ using JWST NIRCam imaging data. We use empirically-constrained galaxy SED templates to define a region in the $F277W-F444W$ vs. $F150W-F277W$ color plane that captures quiescent galaxies at $z>3$. We apply this color selection criteria to the Cosmic Evolution Early Release Science (CEERS) Survey and identify 44 candidate $z\gtrsim3$ quiescent galaxies. Over half of these sources are newly discovered and, on average, exhibit specific star formation rates of post-starburst galaxies. We derive volume density estimates of $n\sim1-4\times10^{-5}$\,Mpc$^{-3}$ at $3< z <5$, finding excellent agreement with existing reports on similar populations in the CEERS field. Thanks to NIRCam's wavelength coverage and sensitivity, this technique provides an efficient tool to search for large samples of these rare galaxies.
