Stringent limits on the masses of the supermassive black holes in seven nearby galaxies

Morelli, L.; Beifiori, A.; Dalla Bontà, E. +6 more

We present new stringent limits on the mass M_• of the central supermassive black hole for a sample of seven nearby galaxies. Our M_• estimates are based on the dynamic modeling of the central width of the nebular emission lines measured over sub-arcsecond apertures with the Hubble Space Telescope. The central stellar velocity …
