Abstract

We report upper limits on the masses of black holes that can be present in the centers of 16 nearby galaxy bulges. These limits MlimBH for our statistically complete sample were derived from the modeling of the central emission-line widths ([N II] or [S II]), observed over a 0.25"×0.2" (R<~9 pc) aperture. The experiment has a mean detection sensitivity of ~3.9×106 Msolar. For three sample members with direct determinations of MBH our upper limits agree within the uncertainties, while in general our upper limits are found to be close to the masses measured in other bulges with global properties similar to ours. Remarkably, our limits are quite close to the recently derived MBH* relation. These results support a picture wherein the black hole mass and overall galaxy structure are closely linked, as galaxies with exceptionally high MBH at a given σ* apparently are rare. Based on observations made with the Hubble Space Telescope, which is operated by AURA, Inc., under NASA contract NAS 5-26555.
