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

Abstract

We present high-resolution HST images of all 35 AGNs with optical\nreverberation-mapping results, which we have modeled to create a nucleus-free\nimage of each AGN host galaxy. From the nucleus-free images, we determine the\nhost-galaxy contribution to ground-based spectroscopic luminosity measurements\nat 5100A. After correcting the luminosities of the AGNs for the contribution\nfrom starlight, we re-examine the Hbeta R-L relationship. Our best fit for the\nrelationship gives a powerlaw slope of 0.52 with a range of 0.45 - 0.59 allowed\nby the uncertainties. This is consistent with our previous findings, and thus\nstill consistent with the naive assumption that all AGNs are simply\nluminosity-scaled versions of each other. We discuss various consistency checks\nrelating to the galaxy modeling and starlight contributions, as well as\npossible systematic errors in the current set of reverberation measurements\nfrom which we determine the form of the R-L relationship.\n
