NGC 3607

NGC 3607 is an unbarred spiral galaxy that forms part of the Leo II Group (NGC 3607 Group) of galaxies.[2] Orbital motions of the globular cluster system[3] imply an unusual poverty of dark matter: perhaps 16±44% of the total mass within 5 effective radii. Recent article shows that its central black hole has a mass of about M = (1.2 ± 0.4) × 108 M[4]
