A graph-based Neural Network surrogate model for accelerating semi-analytical model of galaxy formation and evolution
Xuejie Li, Zhongxu Zhai, Xiaohu Yang +2
Understanding how galaxy populations emerge and evolve from the growth of dark matter structure is a central challenge in galaxy formation theory. Semi-analytic models (SAMs) provi…

A measurement of gas rotation in galaxy groups via the kinetic Sunyaev-Zeldovich effect
Tianyi Yang, Yan-Chuan Cai, Weiguang Cui +5
We utilise the kinetic Sunyaev-Zeldovich effect (kSZ) to measure the rotation of ionised gas within galaxy groups defined in the SDSS-DR7 galaxy sample, via their dipolar imprint o…
