SN Ia host galaxy properties

We study the stellar populations of Type Ia supernova (SN Ia) host galaxies using Sloan Digital Sky Survey (SDSS)-II spectroscopy. The main focus is on the relationships of SN...本研究借助斯隆数字巡天二期（Sloan Digital Sky Survey-II，SDSS-II）的光谱数据，针对Ia型超新星（Type Ia supernova，SN Ia）宿主星系的恒星族群开展探究，核心研究重点为Ia型超新星与宿主星系之间的……关系。
