It doesn't have to be space-infinite to be flat. Standard cosmology works exactly the same if it is a spatially flat but finite manifold, e.g. a 3-torus, as long as all the radii are a bit larger than the observable universe, so I doubt somewhat that there are serious papers empirically arguing for actual infinteness. There are however papers looking for effects of *finiteness* in the cosmic microwave background, but so far no evidence has turned up, with means no more than that the universe is probably at least a bit larger than the observable universe - a conclusion that doesn't surprise anyone, really.
