Observational Evidence for the Kinematic Memory of Cosmic Filaments from Satellite Orbital Orientations
Peng Wang, Wei Wang, Wenting Wang +5
We present an observational study of the kinematic coherence between satellite orbital planes and the cosmic web. Using the SDSS DR12 galaxy sample combined with the Bisous filamen…
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…
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…
Observed Anti-parallel Correlation Between Spiral Galaxy and Cosmic Filament Spins
Hao-da Wang, Peng Wang, Min Bao +7
Understanding the origin of galactic angular momentum and its connection to the cosmic web remains a pivotal issue in galaxy formation. Using kinematic data from the MaNGA survey,…
