Morphological asymmetry of massive low-z galaxies

The morphology of galaxies reflects their assembly history and ongoing dynamical perturbations from the environment. Analyzing stacked i-band images from the Pan-STARRS1 3{pi}...星系的形态学特征反映了其组装历史以及所处环境持续施加的动力学扰动。本研究对来自泛星计划1号（Pan-STARRS1）3π巡天的堆叠i波段图像进行分析……
