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…

The lopsided distribution of satellites of isolated central galaxies
Peng Wang, Noam I. Libeskind, Marcel S. Pawlowski +4
Satellites are not randomly distributed around their central galaxies but show polar and planar structures. In this paper, we investigate the axis-asymmetry or lopsidedness of sate…
