The Contribution of Quasar Absorption Outflows to AGN Feedback
Timothy R. Miller, Nahum Arav, Xinfeng Xu +1
Determining the distance of quasar absorption outflows from the central source (R) and their kinetic luminosity are crucial for understanding their contribution to active galactic…
HST/COS Observations of Quasar Outflows in the 500-1050 Angstrom Rest Frame: VII. Distances and Energetics for 11 Outflows in Five Quasars
Timothy R. Miller, Nahum Arav, Xinfeng Xu +2
From Hubble Space Telescope/Cosmic Origins Spectrograph spectra of five quasars, 16 outflows are detected. For 11 outflows, we are able to constrain their distances to the central…
HST/COS Observations of Quasar Outflows in the 500 -- 1050 Å Rest Frame: VI Wide, Energetic Outflows in SDSS J0755+2306
Xinfeng Xu, Nahum Arav, Timothy Miller +2
We present the analysis of two outflows (S1 at --5500 km s and S2 at --9700 km s) seen in recent HST/COS observations of quasar SDSS J0755+2306 (z = 0.854). The outfl…
HST/COS Observations of Quasar Outflows in the 500-1050 Å Rest Frame: V. Richness of Physical Diagnostics and Ionization Potential-dependent Velocity Shift in PKS J0352-0711
Timothy R. Miller, Nahum Arav, Xinfeng Xu +2
We analyze absorption troughs from two outflows within PKS J0352-0711 (S1 at 1950 km s and S2 at 3150 km s) from spectra taken with Hubble Space Telescope/Cosmi…
HST/COS Observations of Quasar Outflows in the 500 -- 1050 Å Rest Frame: IV. The Largest Broad Absorption Line Acceleration
Xinfeng Xu, Nahum Arav, Timothy Miller +2
We present an analysis of the broad absorption line (BAL) velocity shift that appeared in one of the outflow systems in quasar SDSS J1042+1646. Observations were taken by the Hubbl…
HST/COS Observations of Quasar Outflows in the 500-1050 Å Rest Frame: III. Four Similar Outflows in 2MASS J1051+1247 with Enough Energy to be Major Contributors to AGN Feedback
Timothy R. Miller, Nahum Arav, Xinfeng Xu +2
We detect four very energetic outflows in the Hubble Space Telescope/Cosmic Origin Spectrograph spectra of quasar 2MASS J1051+1247 with a combined kinetic luminosity ()…
