Autor: Tripp, T. M., Wakker, B. P., Jenkins, E. B., Bowers, C. W., Danks, A. C., Green, R. F., Heap, S. R., Joseph, C. L., Kaiser, M. E., Linsky, J. L., Woodgate, B. E.

(Abridged) We present a new high-resolution (7 km/s FWHM) echelle spectrum of 3C 351 obtained with STIS. 3C 351 lies behind the low-latitude edge of high-velocity cloud Complex C, and the new spectrum provides accurate measurements of O I, Si II, Al

Using high S/N STIS echelle spectra (FWHM=7 km/s) of 3C 273, we constrain the metallicities of two Lya clouds in the vicinity of the Virgo cluster. We detect C II, Si II, and Si III absorption lines in the Lya absorber at z = 0.00530. Previous observ

High Velocity Line Emission in the NLR of NGC 4151

Autor: Hutchings, J. B., Crenshaw, D. M., Danks, A. C., Gull, T. R., Kraemer, S. B., Nelson, C. H., Weistrop, D., Kaiser, M. E., Joseph, C. L.

Narrow-band imaging of the nuclear region of NGC 4151 with the Hubble Space Telescope is presented. The filter bandpasses isolate line emission in various high velocity ranges in several ions. Slitless and long-slit spectra of the region with the Spa

UV Absorption Lines from High-Velocity Gas in the Vela Supernova Remnant: New insights from STIS Echelle Observations of HD72089

Autor: Jenkins, E. B., Tripp, T. M., Fitzpatrick, E. L., Lindler, D., Danks, A. C., Beck, T. L., Bowers, C. W., Joseph, C. L., Kaiser, M. E., Kimble, R. A., Kraemer, S. B., Robinson, R. D., Timothy, J. G., Valenti, J. A., Woodgate, B. E.

Publikováno v: Astrophys.J.492:L147-L150,1998

The star HD72089 is located behind the Vela supernova remnant and shows a complex array of high and low velocity interstellar absorption features arising from shocked clouds. A spectrum of this star was recorded over the wavelength range 1196.4 to 13
