Structural properties of host galaxies of light-weight supermassive black holes based on new data from "Hubble" space telescope

In this paper, two-dimensional and one-dimensional photometric modeling of new Hubble Space Telescope data was performed for galaxies hosting intermediate-mass black holes (IMBHs), as well as for objects from an extended sample with black hole masses up to one million solar masses. Using the resulting models, the stellar mass of each galaxy bulge was estimated, and the positions of the galaxies were determined on the black hole mass–bulge mass scaling relation. The location of these galaxies on this relation provides constraints on black hole growth processes in the low-mass regime.
