TL;DR: In this article, the authors proposed a method based on determination of the size of the Broad Line Region from the emission line delay, determination of absolute monochromatic luminosity either from the observed statistical relation or from a model of the formation of the broad line region, and determination of observed monochrome flux from photometry.

TL;DR: In this paper, the authors used the broad line region (BLR) from the emission line delay, the determination of the absolute monochromatic luminosity either from the observed statistical relation or from a model of the formation of the BLR, and the observed monochrome flux from photometry.

TL;DR: Weak emission line quasars are a rare and puzzling group of objects as discussed by the authors, and their line properties are not consistent with the trends expected at high accretion rates, which may indicate that the quasar active phase consists of several sub-phases, each starting with a fresh build-up of the Broad Line Region.

TL;DR: In this article, a simple physical mechanism was proposed for the formation of the Low Ionization Line part of the Broad Line Region in Active Galactic Nuclei, where the local effective temperature of a non-illuminated accretion disk drops below 1000 K and allows for dust formation.

TL;DR: In this article, the authors measured the black hole mass in a very special object, RE J1034+396, one of the two AGNs with QPO oscillations detected in X-rays, and a single bright AGN with optical band totally dominated by starlight.
