There are 2 types of corpses in FO:NV. Corpses of essential (not the technical term) NPCs where you need to loot something off the body for a quest, seem to be flagged to never vanish. Other corpses do vanish.
Whether that carries over to goo/ash piles, I'm not sure yet.
(The first category of corpses is handy because if you miss out on looting a quest item, you're often now stuck and can't complete the quest.)
