Abstract


We have designed an analytical model for the evolutionof anisotropic galactic outflows. Theseoutflows follow the path of least resistance, and thustravel preferentially into low-density regions, away from cosmologicalstructures where galaxies form. We show thatanisotropic outflows can significantly enrich low-densitysystems with metals.
