Observational Evidence for Spin Alignment Between Galaxy Groups and Their Central Galaxies
Peng Wang
We present a systematic observational study of the spin alignment between galaxy groups and their central galaxies using a large spectroscopic sample from the Sloan Digital Sky Sur…
The Cosmic Dance: Observational Detection of Coherent Spin in Galaxy Clusters
Xiao-xiao Tang, Peng Wang, Yu Rong +2
The spin of galaxy clusters encodes key information about their formation, dynamics, and the influence of large-scale structure. However, whether clusters possess statistically sig…
Cosmic filament spin -- II: filament spin and its impact on galaxy spin-filament alignment in a cosmological simulation
Peng Wang, Xiao-Xiao Tang, Hao-Da Wang +7
Observational studies have reported that cosmic filaments on the megaparsec scale exhibit rotational motion. Subsequent simulation studies have shown qualitative agreement with the…
Cosmic filament spin -- I: a comparative study in observation
Xiao-Xiao Tang, Peng Wang, Wei Wang +3
In the cosmic web, filaments play a crucial role in connecting walls to clusters and also act as an important stage for galaxy formation and evolution. Recent observational studies…
