On the HI Content of MaNGA Major Merger Pairs
Autor: Qingzheng Yu, Taotao Fang, Shuai Feng, Bo Zhang, C. Kevin Xu, Yunting Wang, Lei Hao
The role of HI content in galaxy interactions is still under debate. To study the HI content of galaxy pairs at different merging stages, we compile a sample of 66 major-merger galaxy pairs and 433 control galaxies from the SDSS-IV MaNGA IFU survey.

From large-scale environment to CGM angular momentum to star forming activities -- II: quenched galaxies
Autor: Dandan Xu, C. Kevin Xu, Chuan He, Volker Springel, Zheng Cai, Xiaoyang Xia, Lars Hernquist, Sen Wang, S. L. Lu, Shude Mao
The gas needed to sustain star formation in galaxies is supplied by the circumgalactic medium (CGM), which in turn is affected by accretion from large scales. In a series of two papers, we examine the interplay between a galaxy's ambient CGM and cent
