Tidal features in HSC-SSP early-type galaxies

Here we present a statistical study on tidal features around massive early-type galaxies (ETGs). Utilizing the imaging data of the Hyper Suprime-Cam Subaru Strategic Program...本文针对大质量早型星系（massive early-type galaxies，ETGs）周围的潮汐特征展开统计分析。本研究利用斯巴鲁超极相机战略巡天（Hyper Suprime-Cam Subaru Strategic Program）的成像数据……
