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…

The Ionized Gas and Nuclear Environment in NGC 3783 V. Variability and Modeling of the Intrinsic Ultraviolet Absorption
J. R. Gabel, S. B. Kraemer, D. M. Crenshaw +13
We present results on the location, physical conditions, and geometry of the outflow in the Seyfert 1 galaxy NGC 3783 from a study of the variable intrinsic UV absorption. Based on…

The Ionized Gas and Nuclear Environment in NGC 3783 III. Detection of a Decreasing Radial Velocity in an Intrinsic UV Absorber
J. R. Gabel, D. M. Crenshaw, S. B. Kraemer +14
We report an intrinsic absorber with decreasing outflow velocity in the Seyfert 1 galaxy NGC 3783. This is the first detection of a change in radial velocity in an outflow associat…
