2002ApJ...567..237S Limits on the Mass of the Central Black Hole in 16 Nearby Bulges Marc Sarzi, Hans-Walter Rix, Joseph C. Shields, Daniel H. McIntosh, Luis C. Ho, Gregory Rudnick, Alexei V. Filippenko, Wallace L. W. Sargent, and Aaron J. Barth Received 2001 August 3; accepted 2001 October 29 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 M_BH_^lim^ 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" x 0.2" (R <~ 9 pc) aperture. The experiment has a mean detection sensitivity of ~3.9 x 10^6^ M_sun_. For three sample members with direct determinations of M_BH_ 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 M_BH_-{sigma}_*_ relation. These results support a picture wherein the black hole mass and overall galaxy structure are closely linked, as galaxies with exceptionally high M_BH_ at a given {sigma}_*_ apparently are rare.
