Coordinated X-ray and UV absorption within the accretion disk wind of the active galactic nucleus PG 1126-041
M. Giustini, P. Rodríguez Hidalgo, J. N. Reeves +14
Accretion disk winds launched close to supermassive black holes (SMBHs) are a viable mechanism to provide feedback between the SMBH and the host galaxy. We aim to characterize the…
On Synthetic Absorption Line Profiles of Thermally Driven Winds from Active Galactic Nuclei
Shalini Ganguly, Daniel Proga, Tim Waters +7
The warm absorbers observed in more than half of all nearby active galactic nuclei (AGN) are tracers of ionized outflows located at parsec scale distances from the central engine.…
X-ray and multi-epoch optical/UV investigations of BAL to non-BAL quasar transformations
Sameer, W. N. Brandt, S. Anderson +10
We report on an X-ray and optical/UV study of eight Broad Absorption Line (BAL) to non-BAL transforming quasars at 1.7-2.2 over 0.29-4.95 rest-frame years with at lea…
Emergence and Variability of Broad Absorption Line Quasar Outflows
Jesse A. Rogerson, Patrick B. Hall, Nabeel S. Ahmed +3
We isolate a set of quasars that exhibit emergent C iv broad absorption lines (BALs) in their spectra by comparing spectra in the SDSS Data Release 7 and the SDSS/BOSS Data Release…
HST and Ground-Based Spectroscopy of Quasar Outflows: From Mini-BALs to BALs
E. A. Moravec, F. Hamann, D. M. Capellupo +3
Quasar outflows have been posited as a mechanism to couple super-massive black holes to evolution in their host galaxies. We use multi-epoch spectra from the Hubble Space Telescope…
Multi-Epoch Observations of Extremely High-Velocity Emergent Broad Absorption
Jesse A. Rogerson, Patrick B. Hall, Paola Rodríguez Hidalgo +3
We present the discovery of the highest velocity CIV broad absorption line to date in the z=2.47 quasar SDSS J023011.28+005913.6, hereafter J0230. In comparing the public DR7 and D…
