The shape-velocity alignment of satellites forged by tidal locking and dynamical friction
Hao Yang, Wenting Wang, Ting S. Li +8
Utilizing the TNG50 simulation, we study two types of alignments for satellites/subhalos: 1) the alignment of their major axes with the galactocentric radial directions (radial ali…

Modelling the M68 stellar stream with realistic mass loss and frequency distributions in angle-action coordinates
Carles G. Palau, Wenting Wang, Jiaxin Han
We develop a new method for simulating stellar streams generated by globular clusters using angle-action coordinates. This method reproduces the variable mass-loss and variable fre…
