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…

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,…

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…
