2013ApJ...768...76S The Supermassive Black Hole Mass-Spheroid Stellar Mass Relation for Sersic and Core-Sersic Galaxies Scott, Nicholas; Graham, Alister W.; Schombert, James Abstract. We have examined the relationship between supermassive black hole mass (M_BH_) and the stellar mass of the host spheroid (M_sph, *_) for a sample of 75 nearby galaxies. To derive the spheroid stellar masses we used improved Two Micron All Sky Survey K_ s_-band photometry from the ARCHANGEL photometry pipeline. Dividing our sample into core-Sersic and Sersic galaxies, we find that they are described by very different M_BH_-M_sph, *_ relations. For core-Sersic galaxies---which are typically massive and luminous, with M_BH_ >~ 2 x 10^8^ M_sun_---we find M_BH_vprop M_{sph,*}_^{0.97 +/- 0.14}, consistent with other literature relations. However, for the Sersic galaxies---with typically lower masses, M_sph, *_ <~ 3 x 10^10^ M_sun_---we find M_{BH}_ is proportional to {M}_{sph,*}_^{2.22 +/- 0.58}, a dramatically steeper slope that differs by more than 2 standard deviations. This relation confirms that, for Sersic galaxies, M_BH_ is not a constant fraction of M_sph, *_. Sersic galaxies can grow via the accretion of gas which fuels both star formation and the central black hole, as well as through merging. Their black hole grows significantly more rapidly than their host spheroid, prior to growth by dry merging events that produce core-Sersic galaxies, where the black hole and spheroid grow in lockstep. We have additionally compared our Sersic M_BH_-M_sph, *_ relation with the corresponding relation for nuclear star clusters, confirming that the two classes of central massive object follow significantly different scaling relations.

Erratum: "The Supermassive Black Hole Mass-Spheroid Stellar Mass Relation for Sersic and Core-Sersic Galaxies" (2013, ApJ, 768, 76) Scott, Nicholas; Graham, Alister W.; Schombert, James The normalization of the spheroid stellar mass, Msph, * for Sersic galaxies in Equation (4) is incorrectly given as 3.0 10^10^M_sun_. The correct value is 2.0 10^10^M_sun_. Equation (4) should therefore read {see text} This correction does not affect the results or conclusions of this paper in any respect. ===========================================================================
