Swirling around filaments: are large-scale structure vortices spinning up dark haloes?

Abstract:

The kinematic analysis of dark matter and hydrodynamical simulations suggests that the vorticity in large-scale structure is mostly confined to, and predominantly aligned with, their filaments, with an excess of probability of 20 per cent to have the angle between vorticity and filaments direction lower than 60° relative to random orientations. The cross-sections of these filaments are typically partitioned into four quadrantswith opposite vorticity sign, arising frommultiple flows, originati...
