The black hole–bulge relation in AGNs
We used the widths of Hβ and [OIII] emission lines to investigate the black hole–bulge relation in radio-loud AGNs, radio-quiet AGNs and NLS1s. The central black hole mass, Mbh, is estimated from the Hβ line width and the optical luminosity, and the bulge velocity dispersion, σ, is directly from the width of [OIII] line. We found that the radio-quiet AGNs follow the established Mbh − σ relation...
متن کاملBlack Hole Growth & the MBH–Bulge Relations
We present the black hole mass–bulge velocity dispersion relation for a complete sample of 75 soft X-ray selected AGNs. We find that the AGNs with highest accretion rates relative to Eddington lie below the MBH–σ relation of broad line Seyfert 1s, confirming the Mathur et al. (2001) result. The statistical result is robust and not due to any systematic measurement error. This has important cons...
متن کاملUniverse Is the Black Hole
Physico-mathematical parallels between the Expansive Nondecelerative Universe model and black holes justify us to be convicted that each universe can be considered as a black hole. This is why there must exist a fractal arrangement of the Multiuniverse that is boundless both in time and space.
متن کاملThe Black Hole- Bulge Relations in Active Galactic Nuclei
We show that Massive Black Holes of AGNs follow the same approximately linear relation with the luminosity of the host spheroid (bulge) found in normal (quiescent) galaxies, with the black hole mass being 0.002 that of the bulge. We also demonstrate that Narrow line AGNs seem to have a significantly lower Mbh/Lbulge ratio, which implies a new strong correlation between Mbh/Lbulge and the width ...
متن کاملThe Spitzer/IRAC view of black hole–bulge scaling relations
We present a mid-infrared investigation of the scaling relations between supermassive black hole masses (MBH) and the structural parameters of the host spheroids in local galaxies. This work is based on 2D bulge-disc decompositions of Spitzer/IRAC 3.6 μm images of 57 galaxies with MBH estimates. We first verify the accuracy of our decomposition by examining the Fundamental Plane (FP) of spheroi...
