论文摘要
我们提出了修订后的（黑洞质量） - （球体恒星质量）和（黑洞质量） - 基于依赖颜色的恒星质量与光比的比例关系（星系恒星质量）。我们的3.6微米亮度是从多组分分解中获得的，这些分解是凸起，椎间盘，条，Ansae，Ansae，Ansae，环，核成分等。扁豆星系凸起（与最近的合并无关）遵循陡峭的M_BH〜M _ { M_BH〜M _ {*，Ellip}^{1.64 +/- 0.17}的关系由椭圆（E）星系定义，用达尔文术语显示，该星系已被证明是通过标点的平衡而不是渐进的渐进主义而进化的。我们使用球体，即凸起和椭圆形的尺寸质量关系来揭示圆盘 - 胶状合并如何解释椭圆星系中的偏移和较低的m_bh/m _ {*，sph}比率。流行但欺骗性的接近线性M_BH-M _ {*，sph}```红色序列''，其次是凸起人群和椭圆星系，被证明是样本选择的人工制品，结合了凸起和椭圆形的星系，来自不同的M_BH-M_BH-M _ {*，Sph}序列。此外，相对于近乎线性的m_bh -m _ {*，sph}序列，带有“质量质量”黑洞和带有“过度质量”的黑洞的大凸耳星系（包括遗物“红块”） - 不再是远见。我们确认了陡峭的M_BH〜M _ {*，Bulge}^{2.25 +/- 0.39}螺旋星系的关系，并讨论了这项工作的许多含义，包括如何合并而不是（仅）来自Active Galactic核的反馈，从而塑造了Galaxy质量功能的高质量端。我们还解释了为什么由于m _ {*，sph}而没有有用的m_bh-m _ {*，sph} -r_ {
We present revised (black hole mass)-(spheroid stellar mass) and (black hole mass)-(galaxy stellar mass) scaling relations based on colour-dependent stellar mass-to-light ratios. Our 3.6 micron luminosities were obtained from multicomponent decompositions, which accounted for bulges, discs, bars, ansae, rings, nuclear components, etc. The lenticular galaxy bulges (not associated with recent mergers) follow a steep M_bh~M_{*,bulge}^{1.53+/-0.15} relation, offset by roughly an order of magnitude in black hole mass from the M_bh~M_{*,ellip}^{1.64+/-0.17} relation defined by the elliptical (E) galaxies which, in Darwinian terms, are shown to have evolved by punctuated equilibrium rather than gradualism. We use the spheroid, i.e., bulge and elliptical, size-mass relation to reveal how disc-galaxy mergers explain this offset and the dramatically lower M_bh/M_{*,sph} ratios in the elliptical galaxies. The popular but deceptive near-linear M_bh-M_{*,sph} `red sequence', followed by neither the bulge population nor the elliptical galaxies, is shown to be an artefact of sample selection, combining bulges and elliptical galaxies from disparate M_bh-M_{*,sph} sequences. Moreover, both small bulges with `undermassive' black holes and big lenticular galaxies (including relic `red nuggets') with `overmassive' black holes - relative to the near-linear M_bh-M_{*,sph} sequence - are no longer viewed as outliers. We confirm a steep M_bh~M_{*,bulge}^{2.25+/-0.39} relation for spiral galaxies and discuss numerous implications of this work, including how mergers, rather than (only) feedback from active galactic nuclei, have shaped the high-mass end of the galaxy mass function. We also explain why there may be no useful M_bh-M_{*,sph}-R_{e,sph} plane due to M_{*,sph} scaling nearly linearly with R_{e,sph}.
