(Ark, Galaxies With High Surface Brightness)
(1970s list of small/bright galaxies)
Astronomer Marat Arakelian assembled a list of galaxies
with at least a given brightness from a limited area
of the Celestial Sphere, in a paper,
Galaxies With High Surface Brightness, thereby identifying
a number of galaxies with Active Galactic Nuclei.
