致密星系群(CG)是一种特殊的星系系统,其中星系成员之间的距离为星系大小的数量级。星系成员之间的强烈相互作用使CG成为研究环境对星系演化影响的理想实验室。传统的光度选择算法在低红移时会对CG候选星系产生偏差,而光谱识别技术受样本星系光谱不完整性的影响,通常会对高红移候选星系产生偏差。在本研究中,我们将这两种方法联合收割机结合起来,并在Sloan数字巡天的主要星系样本中选择CG,在那里我们还利用了LAMOST光谱和GAMA巡天的互补红移测量。我们获得了迄今为止最大和最完整的CG样本。我们的样本包括6144.CG和8022 CG候选者,这在研究CG的性质和内部星系的演化方面是独一无二的。
A compact group (CG) is a kind of special galaxy system where the galaxy members are separated at distances of the order of galaxy size. The strong interaction between the galaxy members makes CGs ideal labs for studying the environmental effects on galaxy evolution. The traditional photometric selection algorithm biases against the CG candidates at low redshifts, while the spectroscopic identification technique is affected by the spectroscopic.incompleteness of sample galaxies and typically biases against the high redshift candidates. In this study, we combine these two methods and select CGs in the main galaxy sample of the Sloan Digital Sky Survey, where we also have taken the advantages of the complementary redshift measurements from the LAMOST spectral and GAMA surveys. We have obtained the largest and most complete CG samples to date. Our samples include 6144.CGs and 8022 CG candidates, which are unique in the studies of the nature of the CGs and the evolution of the galaxies inside.
