Evidence for a Physically Compact Narrow-Line Region in the Seyfert 1 Galaxy NGC 5548
Steven B. Kraemer, D. Michael Crenshaw, Alexei V. Filippenko +1
We have combined HST/FOS and ground-based spectra of the Seyfert 1 galaxy NGC 5548 to study the narrow emission lines over the 1200 -- 10,000 angstrom region. All of the spectra we…
Spatially Resolved STIS Spectroscopy of SN 1987A: Evidence for Shock Interaction with Circumstellar Gas
G. Sonneborn, C. S. J. Pun, R. A. Kimble +15
Visual and ultraviolet spatially resolved (~ 0."1) spectra of SN 1987A obtained on days 3715 and 3743 with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope sh…
Kinematics of the Nuclear Ionized Gas in the Radio Galaxy M84 (NGC 4374)
G. A. Bower, R. F. Green
We present optical long-slit spectroscopy of the nucleus of the nearby radio galaxy M84 (NGC 4374 = 3C 272.1) obtained with the Space Telescope Imaging Spectrograph (STIS) aboard t…
