Four phases of angular-momentum buildup in high-z galaxies: from cosmic-web streams through an extended ring to disc and bulge
We study the angular-momentum (AM) buildup in high-z massive galaxies using high-
resolution cosmological simulations. The AM originates in co-planar streams of cold gas and …
