Major contributor to AGN feedback: VLT X-shooter observations of SIV BAL QSO outflows
Benoit C. J. Borguet, Nahum Arav, Doug Edmonds +2
We present 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 of this high Eddington r…
BAL phosphorus abundance and evidence for immense ionic column densities in quasar outflows: VLT X-Shooter observations of quasar SDSS J1512+1119
Benoit Borguet, Doug Edmonds, Nahum Arav +2
We present spectroscopic analysis of the broad absorption line outflow in quasar SDSS J1512+1119. In particular, we focus our attention on a kinematic component in which we identif…
Radio spectra and polarisation properties of a bright sample of Radio-Loud Broad Absorption Line Quasars
G. Bruni, K. -H. Mack, E. Salerno +6
The origin of broad-absorption-line quasars (BAL QSOs) is still an open issue. Accounting for ~20% of the QSO population, these objects present broad absorption lines in their opti…
Galactic Scale Absorption Outflow in the Low Luminosity Quasar IRAS~F04250-5718: HST/COS Observations
Doug Edmonds, Benoit Borguet, Nahum Arav +17
We present absorption line analysis of the outflow in the quasar IRAS F04250-5718. Far-ultraviolet data from the Cosmic Origins Spectrograph onboard the Hubble Space Telescope reve…
The nature of proximate damped Lyman alpha systems
Sara L. Ellison, J. Xavier Prochaska, Joseph Hennawi +5
We present high resolution echelle spectra of 7 proximate damped Lyman alpha (PDLA) systems whose relative velocity separation from the background quasar is Delta V < 3000 km/s. Co…
Distance to Multiple Kinematic Components of Quasar Outflows: VLT Observations of QSO 2359-1241 and SDSS J0318-0600
M. A. Bautista, J. P. Dunn, N. Arav +3
Using high resolution VLT spectra, we study the multi-component outflow systems of two quasars exhibiting intrinsic Fe II absorption (QSO 2359-1241 and SDSS J0318-0600). From the e…
