TL;DR: GLAS as discussed by the authors is an upgrade of the William Herschel Telescope's existing natural-guide-star (NGS) AO system NAOMI to incorporate a 20-W Rayleigh laser guide star (LGS) projected to an altitude of 15 km.

TL;DR: In this article, the authors show that most radio-loud broad absorption line quasars (BAL QSOs) are unpolarised or weakly polarised at 8.4 GHz and that they display convex radio spectra which typically flatten at low frequencies and become steeper at high frequencies.

TL;DR: In this paper, the authors explored the spectroscopic characteristics of radio-loud (RL) and radio-quiet (RQ) broad absorption lines (BALs) of quasars with the aim to find a possible explanation for the rarity of RL BAL QSOs.

TL;DR: In this paper, the authors analyzed VLT/X-shooter data for 7 quasars, where they studied the relationship between their broad absorption line (BAL) and emission line outflows.

TL;DR: In this paper, the authors obtained spectra of 60 red, star-like objects (E 1 mJy) with redshift z > 3.6 and showed that these objects are highly luminous in the optical (eight have MB < −28, q0 = 0.5, H 0 = 50 km s −1 Mpc −1 ).
