It must be "fun" trying to determine characteristics of Dwarf Galaxies at a range of 250-500Mly... And given the number from the study which turned out to be far more distant Active Galactic Nuclei "shining through" these Dwarfs, the direction of these Dwarfs must have been in foreground areas of various Galactic Super Clusters.

Regarding the number of Black Holes found outside the Dwarf Galaxy Centers - another element beyond lower gravitational potential is the frequency in which Dwarf Galaxies are distorted in near-collisions with larger neighbors. It would seem that such encounters could readily disturb the "resident" Black Hole, drawing it out of the Dwarf's core just as streamers of Stars are drawn away toward that more massive Galaxy.

Yes, true. The dwarfs would then be less than pristine in some sense.
