We consider an explosion at the center of a halo which forms at theintersection of filaments inside a cosmological pancake, a convenient test-bedmodel for galaxy formation. ASPH/P3M simulations reveal that such explosionsare anisotropic. The energy and metals are channeled into the low densityregions, away from the pancake. The pancake remains essentially undisturbed,even if the explosion is strong enough to blow away all the gas located insidethe halo and reheat the IGM surrounding the pancake. Infall quickly replenishesthis ejected gas and gradually restores the gas fraction as the halo continuesto grow. Estimates of the collapse epoch and SN energy-release for galaxies ofdifferent mass in the CDM model can relate these results to scale-dependentquestions of blow-out and blow-away and their implication for early IGM heatingand metal enrichment and the creation of gas-poor dwarf galaxies.Comment: To appear in "The 20th Texas Symposium on Relativistic Astrophysics",  eds.
