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, support vector machines (SVM) were used to identify galaxies in the WISE × SuperCOSMOS catalogue through an alternative approach of machine learning, which allows to define more complex separations in the multi-colour space than is possible with simple colour cuts, and should provide a more reliable source classification.

TL;DR: In this paper, the authors present the monitoring of the AGN continuum and MgII broad line emission for the quasar HE 0413-4031 ($z=1.38$) based on the six-year monitoring by the South African Large Telescope (SALT).

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).
