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…
Galaxy Group Spin Alignment with Cosmic Filament in the TNG Simulation
Wei Wang, Peng Wang, Yu Rong +2
We investigate the alignment between the spin vectors of galaxy groups and the axes of their nearest cosmic filaments using the TNG300-1 cosmological hydrodynamical simulation. By…
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,…
Orthogonal Alignment of Galaxy Group Angular Momentum with Cosmic Filament Spines: An Observational Study
Yu Rong, Peng Wang, Xiao-xiao Tang
We investigate the alignment between the angular momenta of galaxy groups and the spines of their associated cosmic filaments. Our results demonstrate a significant tendency for th…
The large-scale structure supplies the formation of gas-star misaligned galaxies
Min Bao, Yanmei Chen, Qiusheng Gu +3
Using the integral field unit data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we build a sample of gas-star misaligned galaxies. The large-scale e…
Halo spin and orientation in Interacting Dark Matter Dark Energy Cosmology
Guandi Zhao, Jiajun Zhang, Peng Wang +1
In recent years, the interaction between dark matter (DM) and dark energy (DE) has become a topic of interest in cosmology. Interacting dark matter-dark energy (IDE) models have a…
Alignment of Blue/Green and Red Early-type Galaxies with Large-scale Filaments Reveals Distinct Evolutionary Pathways
Yu Rong, Peng Wang
We investigate the alignment of non-red early-type galaxies (ETGs) with blue or green colors within large-scale filaments and compare this alignment pattern with that of red ETGs.…
