TL;DR: In this article, high-resolution Very Large Telescope observations of the broad absorption line quasar SDSS J0318-0600 were used to extract accurate ionic column densities and determine an electron number density of ne = 103.3±0.2 cm−3 for the main outflow absorption component.
Journal ArticleDOI
Quasar outflows and AGN feedback in the extreme UV: HST/COS observations of HE 0238−1904
TL;DR: In this article, absorption troughs from three important ions are measured: O IV and O IV* that allow us to obtain the distance of high ionization outflows from the AGN; second, Ne VIII and Mg X that are sensitive to the very high ionisation phase of the outflow.

Major Contributor to AGN Feedback: VLT X-shooter Observations of S IV BALQSO Outflows
TL;DR: The most energetic BALQSO outflow measured to date, with a kinetic luminosity of at least 10{sup 46} erg s{sup -1}, was reported in this paper.

Major contributor to AGN feedback: VLT X-shooter observations of SIV BAL QSO outflows
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: In this article, the authors used the HST/COS data from a massive multi-wavelength monitoring campaign on the bright Seyfert I galaxy Mrk 509, in combination with archival HST and STIS data, to constrain the location of the various kinematic components of the outflow.
