A Photometric Method to Determine Supermassive Black Hole Masses
نویسندگان
چکیده
We report the discovery of a strong correlation between the shape of a bulge’s light-profile and the mass of its central supermassive black hole (Mbh). We find that log(Mbh/M⊙) = 2.91(±0.38) log(n) + 6.37(±0.21), where n is the Sérsic r shape index. This correlation is shown to be at least as strong as the relationship between the logarithm of the stellar velocity dispersion and logMbh and has comparable scatter.

The distribution of supermassive black holes in the nuclei of nearby galaxies
The growth of supermassive black holes by merging and accretion in hierarchical models of galaxy formation is studied by means of Monte Carlo simulations. A tight linear relation between masses of black holes and masses of bulges arises if the mass accreted by supermassive black holes scales linearly with the mass forming stars and if the redshift evolution of mass accretion tracks closely that...
متن کاملA SuperMassive Black Hole Fundamental Plane for Ellipticals
We obtain the coefficients of a new fundamental plane for supermassive black holes at the centers of elliptical galaxies, involving measured central black hole mass and photometric parameters which define the light distribution. The galaxies are tightly distributed around this mass fundamental plane, with improvement in the rms residual over those obtained from the MBH − σ and MBH − L relations...
متن کاملA hierarchical search for gravitational waves from supermassive black hole binary mergers
We present a method to search for gravitational waves from coalescing supermassive binary black holes in LISA data. The search utilizes the F-statistic to maximize over, and determine the values of, the extrinsic parameters of the binary system. The intrinsic parameters are searched over hierarchically using stochastically generated multi-dimensional template banks to recover the masses and sky...
متن کاملA three-stage search for supermassive black-hole binaries in LISA data
Gravitational waves from the inspiral and coalescence of supermassive black-hole (SMBH) binaries with masses m1 ∼ m2 ∼ 10 are likely to be one of the strongest sources for the Laser Interferometer Space Antenna (LISA). We describe a three-stage data-analysis pipeline designed to search for and measure the parameters of SMBH binaries in LISA data. The first stage uses a time– frequency track-sea...
متن کاملThe Accuracy of Supermassive Black Hole Masses Determined by the Single-epoch Spectrum (dibai) Method
The first set of supermassive black hole mass estimates, published from 1977 to 1984 by É. A. Dibai, are shown to be in excellent agreement with recent reverberation-mapping estimates. Comparison of the masses of 17 AGNs covering a mass range from about 10 to 10M⊙ shows that the Dibai mass estimates agree with reverberation-mapping mass estimates to significantly better than ±0.3 dex and were, ...
