TL;DR: In this article, the authors present an updated and revised analysis of the relationship between the H{beta} broadline region (BLR) radius and the luminosity of the active galactic nucleus (AGN).

TL;DR: In this paper, the authors presented the most extensive consistent analysis to date of z>4 QSOs with observed NIR spectra, combining three new z~6 objects from our ongoing VLT-ISAAC program with nineteen 4 =-037 (Lbol/LEdd~043) with a scatter of 020 dex for the z >4 sample and the =-080 (lbol/Ldd~016) with an average of 024 dex for each of the 035 4 sources.

TL;DR: The first high-redshift (z > 5.7) quasar from the Panoramic Survey Telescope and Rapid Response System 1 (Pan-STARRS1 or PS1) was discovered in this article.

TL;DR: In this paper, the authors compare mass estimates based on line dispersion and FWHM, and show that the luminosity of the Hbeta broad component can be used instead without any loss of precision, thus eliminating the difficulty of accurately accounting for the host-galaxy contribution to the observed luminosity.
