The Stellar-Dynamical Search for Supermassive Black Holes in Galactic Nuclei

  title={The Stellar-Dynamical Search for Supermassive Black Holes in Galactic Nuclei},
  author={John Kormendy},
The robustness of stellar-dynamical black hole (BH) mass measurements is illustrated using six galaxies that have results from independent research groups. Derived BH masses have remained constant to a factor of ∼ 2 as spatial resolution has improved by a factor of 2 – 330, as velocity distributions have been measured in increasing detail, and as the analysis has improved from spherical, isotropic models to axisymmetric, three-integral models. This gives us confidence that the masses are…

Relativistic dynamics and extreme mass ratio inspirals
A unique probe of these regions is the gravitational radiation emitted by some compact stars very close to the black holes and which could be surveyed by a millihertz gravitational-wave interferometer scrutinizing the range of masses fundamental to understanding the origin and growth of supermassive black holes.
The mass of the black hole in Centaurus A from SINFONI AO-assisted integral-field observations of stellar kinematics
We present a determination of the mass of the supermassive black hole (BH) and the nuclear stellar orbital distribution of the elliptical galaxy Centaurus A (Cen A) (NGC 5128) using high-resolution
The gravitational capture of compact objects by massive black holes
The gravitational capture of a stellar-mass compact object (CO) by a supermassive black hole is a unique probe of gravity in the strong field regime. Because of the large mass ratio, we call these
Accretion of stars on to a massive black hole: a realistic diffusion model and numerical studies
We present a study of the secular evolution of a spherical stellar system with a central star-accreting black hole (BH) using the anisotropic gaseous model. This method solves numerically moment
Estimating black hole masses in triaxial galaxies
Most of the supermassive black hole mass (M • ) estimates based on stellar kinematics use the assumption that galaxies are axisymmetric oblate spheroids or spherical. Here, we use fully general
Constraining scalar fields with stellar kinematics and collisional dark matter
The existence and detection of scalar fields could provide solutions to long- standing puzzles about the nature of dark matter, the dark compact objects at the centre of most galaxies, and other
A comprehensive set of simulations of high-velocity collisions between main-sequence stars
We report on a very large set of simulations of collisions between two main-sequence (MS) stars. These computations were carried out with the smoothed particle hydrodynamics method. Realistic stellar
Gravitomagnetic Effects in Compact Binary Systems: A Study of Spin-Enhanced Orbits around Kerr Black Holes
An important subject in current gravity research concerns the evolution of compact binary systems in which both members spin, particularly in the extreme mass ratio limit. Previous research has
A Near-Infrared-selected Galaxy Redshift Survey
This thesis presents work on galaxy evolution at redshifts 0 < z < 1.5 from a near-infrared selected galaxy redshift survey and much larger optically selected galaxy catalogues where distances were
Radio morphology–accretion mode link in Fanaroff–Riley type II low-excitation radio galaxies
Fanaroff-Riley II low-excitation radio galaxies (FRII-LERGs) are characterized by weak nuclear excitation on pc-scales and by properties typical of powerful FRIIs (defined as high-excitation,
