The boundary of cosmic filaments
Wei Wang, Peng Wang, Hong Guo +12
For decades, the boundary of cosmic filaments have been a subject of debate. In this work, we determine the physically-motivated radii of filaments by constructing stacked galaxy n…

Lagrangian space remapping and the angular momentum reconstruction from cosmic structures
Sijia Li, Ming-Jie Sheng, Haikun Li +1
Large scale structures provide valuable information of the primordial perturbations that encode the secrets of the origin of the Universe. It is an essential step to map between ob…

Spin speed correlations and the evolution of galaxy-halo systems
Ming-Jie Sheng, Lin Zhu, Hao-Ran Yu +4
Galaxy angular momenta (spins) contain valuable cosmological information, complementing their positions and velocities. The baryonic spin direction of galaxies has been probed as a…
