Robust Supermassive Black Hole Spin Mass-Energy Characteristics: A New Method and Results
Ruth A. Daly
The rotational properties of astrophysical black holes are fundamental quantities that characterization the black holes. A new method to empirically determine the spin mass-energy…
Black Hole Mass Accretion Rates and Efficiency Factors for over 750 AGN and Multiple GBH
Ruth A. Daly
Mass accretion rates in dimensionless and physical units, and efficiency factors describing the total radiant luminosity of the disk and the beam power of the outflow are studied h…
Black Hole Spin Energy Contribution to Black Hole Mass and the Spin Energy Reservoir
Ruth A. Daly
The mass of a black hole is the sum of the irreducible mass and the mass associated with the rotational or spin energy of the black hole. The contribution of spin energy (divided b…
Black Hole Spin and Accretion Disk Magnetic Field Strength Estimates for more than 750 AGN and Multiple GBH
Ruth A. Daly
Black hole systems, comprised of a black hole, accretion disk, and collimated outflow are studied here. Three AGN samples including 753 AGN, and 102 measurements of 4 GBH are studi…
A VLA-GMRT Look at 11 Powerful FR II Quasars
S. Vaddi, P. Kharb, R. A. Daly +5
We present results from 1.4 and 5 GHz observations at matched resolution with the Karl G. Jansky Very Large Array (VLA) of 11 powerful 3C FR II quasars. We examine the 11 quasars a…
A Fundamental Line of Black Hole Activity
Ruth. A. Daly, Douglas A. Stout, Jeremy N. Mysliwiec
Black hole systems with outflows are characterized by intrinsic physical quantities such as the outflow beam power, , the bolometric accretion disk luminosity, , and…
