Magnetically Driven Jets in the Kerr Metric
John F. Hawley, Julian H. Krolik
We compute a series of three-dimensional general relativistic magnetohydrodynamic simulations of accretion flows in the Kerr metric to investigate the properties of the unbound out…
Vertical Structure of Gas Pressure-Dominated Accretion Disks with Local Dissipation of Turbulence and Radiative Transport
Shigenobu Hirose, Julian H. Krolik, James M. Stone
(shortened) We calculate the vertical structure of a local patch of an accretion disk in which heating by dissipation of MRI-driven MHD turbulence is balanced by radiative cooling.…
Chandra and XMM Observations of Type II Quasars from the SDSS
A. Ptak, N. Zakamska, M. Strauss +4
We are carrying out sensitive X-ray observations with Chandra and XMM of type II quasars selected from the Sloan Digital Sky Survey based on their optical emission line properties.…
Intrinsic Curvature in the X-ray Spectra of BL Lacertae Objects
Eric S. Perlman, Greg Madejski, Markos Georganopoulos +10
We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The survey was designed to l…
Non-LTE Spectra of Accretion Disks Around Intermediate-Mass Black Holes
Y. Hui, J. H. Krolik, I. Hubeny
We have calculated the structures and the emergent spectra of stationary, geometrically thin accretion disks around 100 and 1000 M_sun black holes in both the Schwarzschild and ext…
Active Galactic Nuclei in the Sloan Digital Sky Survey: I. Sample Selection
Lei Hao, Michael A. Strauss, Christy A. Tremonti +18
We have compiled a large sample of low-redshift active galactic nuclei (AGN) identified via their emission line characteristics from the spectroscopic data of the Sloan Digital Sky…
Active Galactic Nuclei in the Sloan Digital Sky Survey: II. Emission-Line Luminosity Function
Lei Hao, Michael A. Strauss, Xiaohui Fan +18
The emission line luminosity function of active galactic nuclei (AGN) is measured from about 3000 AGN included in the main galaxy sample of the Sloan Digital Sky Survey within a re…
