From inter-filamentary gas to filaments and hubs: gas flow in the Monoceros R2 star-forming hub-filament system.

Caption

Illustration of the Monoceros R2 hub–filament system showing how the gas flows along the filaments (green arrows) and in the inter-filament regions (blue arrows) towards the central hub. The analysis showed that gas within dense filaments flows toward the hub much faster than gas in the surrounding inter-filament regions. At the same time, a fraction of the gas in the inter-filament regions moves sideways into nearby filaments, replenishing them with fresh material before continuing toward the hub, supporting star formation
