Magnetically Driven Accretion Flows in the Kerr Metric II: Structure of the Magnetic Field
Shigenobu Hirose, Julian H. Krolik, Jean-Pierre De Villiers +1
We present a detailed analysis of the magnetic field structure found in general relativistic 3D MHD simulations of accreting tori in the Kerr metric with different black hole spins…
Type II Quasars from the SDSS
Nadia L. Zakamska, Michael A. Strauss, Julian H. Krolik +1
Type II quasars are suggested by unification models of Active Galactic Nuclei as luminous analogs of Seyfert 2 galaxies. A number of different methods have been used hitherto to di…
Candidate Type II Quasars from the Sloan Digital Sky Survey: I. Selection and Optical Properties of a Sample at 0.3<Z<0.83
Nadia L. Zakamska, Michael A. Strauss, Julian H. Krolik +12
Type II quasars are the long-sought luminous analogs of type II (narrow emission line) Seyfert galaxies, suggested by unification models of active galactic nuclei (AGN) and postula…
Magnetically Driven Accretion Flows in the Kerr Metric I: Models and Overall Structure
Jean-Pierre De Villiers, John F. Hawley, Julian H. Krolik
This is the first in a series of papers that investigate the properties of accretion flows in the Kerr metric through three-dimensional, general relativistic magnetohydrodynamic si…
Local Three-Dimensional Simulations of Magneto-Rotational Instability in Radiation-Dominated Accretion Disks
N. J. Turner, J. M. Stone, J. H. Krolik +1
We examine the small-scale dynamics of black hole accretion disks in which radiation pressure exceeds gas pressure. Local patches of disk are modeled by numerically integrating the…
A Catalog of Broad Absorption Line Quasars from the Sloan Digital Sky Survey Early Data Release
Timothy A. Reichard, Gordon T. Richards, Donald P. Schneider +9
We present a catalog of 224 broad absorption line quasars (BALQSOs) from the Sloan Digital Sky Survey's Early Data Release Quasar Catalog, including a relatively complete and homog…
