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…
BAL Outflow Contribution to AGN Feedback: Frequency of S iv Outflows in the SDSS
Jay P. Dunn, Nahum Arav, Kentaro Aoki +4
We present a study of Broad Absorption Line (BAL) quasar outflows that show S IV ?1063 and S IV* ?1073 troughs. The fractional abundance of S IV and C IV peak at similar value of t…
Multiwavelength Campaign on Mrk 509 X. Lower limit on the distance of the absorber from HST COS and STIS spectroscopy
N. Arav, D. Edmonds, B. Borguet +15
Active Galactic Nuclei often show evidence of photoionized outflows. A major uncertainty in models for these outflows is the distance () to the gas from the central black hole.…
A 10 kpc Scale Seyfert Galaxy Outflow: HST/COS Observations of IRAS F22456-5125
Benoit Borguet, Doug Edmonds, Nahum Arav +2
We present analysis of the UV-spectrum of the low-z AGN IRAS-F22456-5125 obtained with the Cosmic Origins Spectrograph on board the Hubble Space Telescope. The spectrum reveals six…
Multiwavelength campaign on Mrk 509 IX. The Galactic foreground
C. Pinto, G. A. Kriss, J. S. Kaastra +5
The diffuse gas in and nearby the Milky Way plays an important role in the evolution of the entire Galaxy. It has a complex structure characterized by neutral, weakly and highly io…
