2001ApJ...563L..11G A Correlation between Galaxy Light Concentration and Supermassive Black Hole Mass Alister W. Graham, Peter Erwin, N. Caon, and I. Trujillo Instituto de Astrofisica de Canarias, La Laguna, E-38200 Tenerife, Spain; agraham@ll.iac.es, erwin@ll.iac.es, ncaon@ll.iac.es, itc@ll.iac.es Received 2001 September 14; accepted 2001 November 6; published 2001 November 21 ABSTRACT We present evidence for a strong correlation between the concentration of bulges and the mass of their central supermassive black hole (M_bh_) - more concentrated bulges have more massive black holes. Using C_r_e__(1/3) from Trujillo, Graham, & Caon as a measure of bulge concentration, we find that log(M_bh_/M_sun_) = 6.81(+/-0.95)C_r_e__(1/3) + 5.03 +/- 0.41. This correlation is shown to be marginally stronger (Spearman's r_s_ = 0.91) than the relationship between the logarithm of the stellar velocity dispersion and log M_bh_ (Spearman's r_s_ = 0.86) and has comparable or less scatter (0.31 dex in log M_bh_, which decreases to 0.19 dex when we use only those galaxies whose supermassive black hole radii of influence are resolved and we remove one well-understood outlying data point). Subject headings: black hole physics - galaxies: fundamental parameters - galaxies: kinematics and dynamics - galaxies: nuclei - galaxies: photometry - galaxies: structure
