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…
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…
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.…
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…
