That serve this Pond's black face for mask
And still at yonder broken edges
O' the hole, where up the bubbles glisten,
After my heart I look and listen.

The possibilities include intermediate mass black holes, with masses between those of stellar black holes and AGN (e.g.

An AGN has not been detected in this galaxy at other wavelengths, but from the central surface birghtness profile van der Marel (1999) estimated a black hole mass of 2.29 × 108M⊙ for this galaxy. A correlation has also been found between bulge luminosity and black hole mass (Kormendy & Gebhardt 2001).
X-ray Source Population in the Elliptical Galaxy NGC 720 with Chandra
