Absorption and Reddening in the Seyfert Galaxy NGC 3227

D. M. Crenshaw, S. B. Kraemer, F. C. Bruhweiler +1

We have obtained low-dispersion spectra of NGC 3227 with the Space Telescope Imaging Spectrograph (STIS) to study the intrinsic UV absorption and the reddening of the nucleus in th…

STIS observations of five hot white dwarfs

N. P. Bannister, M. A. Barstow, J. B. Holberg +1

We present some early results from a study of five hot DA white dwarf stars, based on spectra obtained using STIS. All show multiple components in one or more of the strong resonan…

The D/H Ratio in Interstellar Gas Towards G191-B2B

M. S. Sahu, W. Landsman, F. C. Bruhweiler +7

We reinvestigate the question of spatial variation of the local D/H abundance, using both archival GHRS spectra, and new echelle spectra of G191-B2B obtained with the Space Telesco…

Multi-wavelength Observations of 3C 273 in 1993-1995

C. von Montigny

We present the results of the multi-wavelength campaigns on 3C 273 in 1993-1995. During the observations in late 1993 this quasar showed an increase of its flux for energies greate…
