We have designed an analytical model for the evolution of anisotropic
galactic outflows. These outflows follow the path of least resistance, and thus
travel preferentially into low-density regions, away from cosmological
structures where galaxies form. We show that anisotropic outflows can
significantly enrich low-density systems with metals.Comment: Proceedings of Chemodynamics 2006, Lyon, 2 pages, 1 figure, style
