The Effects of Low-Temperature Dielectronic Recombination on the Relative Populations of the Fe M-Shell States
S. B. Kraemer, G. J. Ferland, J. R. Gabel
We examine the effects of low-temperature, or , dielectronic recombination (DR) on the ionization balance of the Fe M-Shell (Fe IX through Fe XVI). Since rates…
The Host Galaxies of Narrow-Line Seyfert 1s: Evidence for Bar-Driven Fueling
D. M. Crenshaw, S. B. Kraemer, J. R. Gabel
We present a study of the host-galaxy morphologies of narrow- and broad-line Seyfert 1 galaxies (NLS1s and BLS1s) based on broad-band optical images from the Hubble Space Telescope…
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…
Simultaneous UV and X-ray Spectroscopy of the Seyfert 1 Galaxy NGC 5548. I. Physical Conditions in the UV Absorbers
D. M. Crenshaw, S. B. Kraemer, J. R. Gabel +9
We present new UV spectra of the nucleus of the Seyfert 1 galaxy NGC 5548, which we obtained with the Space Telescope Imaging Spectrograph at high spectral resolution, in conjuncti…
