[WH40K] Do the Chaos Gods have an impact beyond our galaxy?

Do the Chaos Gods draw power from the hate/plotting/lust/rotting of beings all across the universe, or are they tied to our galaxy? If the latter, why? 

For that matter, what about the Old Ones or other Warp-Beings?

We don't know. What little records we have on the Old Ones don't mention anything about their activities outside the galaxy. And the closest galaxy is still to far away to use warp travel (the chances of getting lost is too high). The only lifeform we know that comes from outside the galaxy are the Tyranids and they won't be talking anytime soon.

Although there was this one rumor; we sent out probes sometime during the Great Crusade and they came back filled with the chanting of Orks.
