[67.01] From the Interstellar Medium to Massive Black Holes: First Results from STIS

R. F. Green (NOAO/KPNO), STIS Instrument Definition Team

The Space Telescope Imaging Spectrograph (STIS) is a versatile, long-slit spectrograph that exploits the angular resolution, optical/UV wavelength coverage, and darker sky of the HST. The wavelength coverage is 115-1000 nm in four bands; spectral resolving powers range from 26 to 200,000. The MAMA and CCD 2-dimensional detectors provide order-of-magnitude improvements over the first generation spectrographs. On-orbit verification and early science observations show that the instrument is performing very well.

Three science vignettes demonstrate the capabilities of STIS:

\bullet The blast wave is interacting with the circumstellar ejecta of the precursor of SN 1987A.

\bullet High resolution, high S/N UV spectroscopy of a hot star background probe reveals physical conditions in complex regions of the interstellar medium.

\bullet Long-slit spectra through the nuclei of nearby galaxies confirm the presence and action of supermassive black holes.
