TL;DR: The most energetic BALQSO outflow measured to date, with a kinetic luminosity of at least 10^46 ergs/s, which is 5% of the bolometric luminosity as discussed by the authors, is located at about 300 pc from the quasar and has a velocity of roughly 8000 km/s.

TL;DR: The brightness of the night sky above La Palma was measured on 427 CCD images taken with the Isaac Newton and Jacobus Kapteyn Telescopes on 63 nights during 1987 - 1996 as discussed by the authors.

TL;DR: In this paper, high-resolution spectroscopic VLT observations of the outflow seen in QSO 2359-1241 were used to investigate the physical distribution of the material in front of the source and by that to determine the column densities of the absorbed troughs.

TL;DR: In this article, the spectral properties of these SNe are discussed in the context of previously proposed scenarios for faint SNe: low mass progenitors producing under-energetic SNe; SNe with ejecta constrained by a circumstellar medium; and outbursts of massive Luminous Blue Variables (LBVs).

TL;DR: In this article, the authors present a monitoring study of SN 2004A and probable discovery of a progenitor star in pre-explosion Hubble Space Telescope (HST) images.
