With two black holes where her breasts should be,
Left to rot in the rain.

By tears, raging blindly as, sense by sense, My mother is sucked away?

Just now, beneath the heavy sedges
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 first case is for a single boosted black hole; the second is for two black holes, separated by a “small” distance and boosted towards each other.

The possibilities include intermediate mass black holes, with masses between those of stellar black holes and AGN (e.g.
X-ray Source Population in the Elliptical Galaxy NGC 720 with Chandra
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
For two holes the maximal value of 50% can be derived by starting with two extremal black holes (i.e. of maximal angular momentum: J = m2 in geometric units) which merge to form a single unspinning black hole .
