From larger-scale cold-gas angular-momentum environment to galaxy star-formation activeness
Sen Wang, Dandan Xu, Shengdong Lu
We study the influence of the ambient large-scale cold-gas vorticity on the specific star formation rate (sSFR) of central galaxies with stellar masses of $10.0<\log\,M_{\ast}/\mat…

Disparate Effects of Circumgalactic Medium Angular Momentum in IllustrisTNG and SIMBA
Kexin Liu, Hong Guo, Sen Wang +4
In this study, we examine the role of circumgalactic medium (CGM) angular momentum () on star formation in galaxies, whose influence is currently not well understood.…

Kinematical coherence between satellite galaxies and host stellar discs for MaNGA & SAMI galaxies
Sen Wang, Dandan Xu, Shengdong Lu +1
The effect of angular momentum on galaxy formation and evolution has been studied for several decades. Our recent two papers using IllustrisTNG-100 simulation have revealed the acq…
