Could they be Dyson spheres?

  Not when there are whole galaxies in the center. That dot in the middle of the ORC in the picture is an entire galaxy. You also wouldn't be able to see through a Dyson sphere.

    From the article: “ We still have no idea how big or far away they are. They could be objects in our galaxy, perhaps a few light-years across, or they could be far away in the universe and maybe millions of light years across.”

      If it is on the far side of a galaxy it has to be bigger than that galaxy. Dyson swarms are about 6e9 times smaller radius than our galaxy.
