As the title asks; is Omega Centauri (NGC 5139) in ED? I searched for both names in the galaxy map and neither came up.

Probably not.
Globular clusters orbit our galaxy outside the galactic disk. They contain tens of thousands to millions of member stars that are bound together by gravity, and remain intact for billions of years.
This is in the Milky Way galaxy, refer to the link in my OP. It is only 15,800 LY's from Sol so it should be in the ED galaxy.
The galaxy map, if I am not mistaken, doesn't let you search for clusters.
As for where it "should" be, it should be several thousand light-years Up from the Hawking's Gap region.
Edit to add: somewhere around here:
