TL;DR: In this paper, the authors adopt a theory-motivated approach to identify the principal mechanism responsible for the complex phenomenon of the Broad Line Region in Active Galactic Nuclei, where the role of dust is essential.

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.

TL;DR: In this article, the authors measured the rest-frame time-lag of a distant bright quasar CTS C30.10 (z = 0.90052) with the Southern African Large Telescope (SALT).

TL;DR: In this article, the authors used the Southern African Large Telescope (SALT) with the Robert Stobie Spectrograph (RSS) for ten spectroscopic observations of quasar HE 0435-4312 (z = 1.2231) over a period of three years (Dec 23/24 2012 to Dec 7/8 2015).
