The Black Hole Mass-Bulge Luminosity Relationship for Active Galactic Nuclei from Reverberation Mapping and Hubble Space Telescope Imaging
Misty C. Bentz, Bradley M. Peterson, Richard W. Pogge +1
We investigate the relationship between black hole mass and bulge luminosity for AGNs with reverberation-based black hole mass measurements and bulge luminosities from two-dimensio…
The Radius-Luminosity Relationship for Active Galactic Nuclei: The Effect of Host-Galaxy Starlight on Luminosity Measurements II. The Full Sample of Reverberation-Mapped AGNs
Misty C. Bentz, Bradley M. Peterson, Hagai Netzer +2
We present high-resolution HST images of all 35 AGNs with optical reverberation-mapping results, which we have modeled to create a nucleus-free image of each AGN host galaxy. From…
Determining Quasar Black Hole Mass Functions from their Broad Emission Lines: Application to the Bright Quasar Survey
Brandon C. Kelly, Marianne Vestergaard, Xiaohui Fan
We describe a Bayesian approach to estimating quasar black hole mass functions (BHMF) when using the broad emission lines to estimate black hole mass. We show how using the broad l…
Systematic Uncertainties in Black Hole Masses Determined from Single Epoch Spectra
Kelly D. Denney, Bradley M. Peterson, Matthias Dietrich +2
We explore the nature of systematic errors that can arise in measurement of black hole masses from single-epoch spectra of active galactic nuclei (AGNs) by utilizing the many epoch…
A Flexible Method of Estimating Luminosity Functions
Brandon C. Kelly, Xiaohui Fan, Marianne Vestergaard
We describe a Bayesian approach to estimating luminosity functions. We derive the likelihood function and posterior probability distribution for the luminosity function, given the…
A Sample of Quasars with Strong Nitrogen Emission Lines from the Sloan Digital Sky Survey
Linhua Jiang, Xiaohui Fan, M. Vestergaard
We report on 293 quasars with strong NIV] lambda 1486 or NIII] lambda 1750 emission lines (rest-frame equivalent width > 3 Å) at 1.7 < z < 4.0 selected from the Sloan Digital Sky S…
