Title: The kinematically decoupled galaxies from SDSS-IV/MaNGA

Speaker: 陈燕梅 副教授

Place: Physics Building 573, Haiyun Campus, Xiamen University
Abstract: In this talk, I will introduce the properties of kinematically decoupled galaxies selected from MaNGA survey, including (1) galaxies with kinematically misaligned gas and stars; (2) galaxies with two counter-rotating stellar disks, which are defined as 2sigma galaxies in the literatures. From the properties such as stellar population, metallicity, environment, I will try to discuss the formation mechanisms of these objects.
