Zippers and Twisters: Planes of Satellite Galaxies Emerge from Whirling and Shocking Gas Streams in the Cosmic Web

Abstract We investigate dwarf satellite systems around massive centrals analogs (Milky Way to Centaurus A) in the NewHorizon simulation. Using simple estimators limiting overdetection, we identify planes of satellites comparable to observations in 30%–70% of cases. The full sampl...
