Emergence of a Broad-Absorption-Line Outflow in the Narrow-line Seyfert 1 Galaxy WPVS 007
Karen M. Leighly, Fred Hamann, Darrin A. Casebeer +1
We report results from a 2003 FUSE observation, and reanalysis of a 1996 HST observation of the unusual X-ray transient Narrow-line Seyfert 1 galaxy WPVS 007. The HST FOS spectrum…
Comparative Direct Analysis of Type Ia Supernova Spectra. V. Insights from A Larger Sample and Quantitative Subclassification
David Branch, Leeann Chau Dang, E. Baron
A comparative study of optical spectra of Type Ia supernovae (SNe Ia) is extended, in the light of new data. The discussion is framed in terms of the four groups defined in previou…
A Self-Consistent NLTE-Spectra Synthesis Model of FeLoBAL QSOs
Darrin Casebeer, E. Baron, Karen Leighly +2
We present detailed radiative transfer spectral synthesis models for the Iron Low Ionization Broad Absorption Line (FeLoBAL) active galactic nuclei (AGN) FIRST J121442.3+280329 and…
Comparative Direct Analysis of Type Ia Supernova Spectra. IV. Postmaximum
David Branch, David J. Jeffery, Jerod Parrent +6
A comparative study of optical spectra of Type Ia supernovae (SNe Ia) obtained near 1 week, 3 weeks, and 3 months after maximum light is presented. Most members of the four groups…
Comparative Direct Analysis of Type Ia Supernova Spectra. III. Premaximum
David Branch, M. A. Troxel, David J. Jeffery +8
A comparative study of spectra of 21 Type Ia supernovae (SNe Ia) obtained about one week before maximum light, and 8 spectra obtained 11 or more days before maximum, is presented.…
Photoionization Models of the Broad-line Region
Karen M. Leighly, Darrin Casebeer
The strong broad emission lines in the optical and UV spectra of Active Galactic Nuclei (AGN) are important for several reasons. Not only do they give us information about the stru…
