Dark and Baryonic Matter in Bright Spiral Galaxies. I. Near-Infrared and Optical Broadband Surface Photometry of 30 Galaxies
de Jong, Roelof S.; Pogge, Richard W.; Kassin, Susan A.
We present photometrically calibrated images and surface photometry in the B, V, R, J, H, and K bands of 25, and in the g, r, and K bands of five nearby bright (B0T<12.5 mag) spiral galaxies with inclinations of 30°-65° spanning the Hubble sequence from Sa to Scd. Data are from The Ohio State University Bright Spiral Galax…
Eta Carinae across the 2003.5 Minimum: The Character and Variability of the Ejecta Absorption in the Near-Ultraviolet
Gull, T. R.; Nielsen, K. E.; Kober, G. Vieira
We present Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) high-resolution near-ultraviolet (NUV) spectra of η Car's central source recorded before, during and after the 2003.5 spectroscopic minimum. Our focus is on the narrow absorption lines formed in multiple circumstellar shells, superimposed on the broad P Cygni stell…
The Intercalibration of SOHO EIT, CDS-NIS, and TRACE
Warren, Harry P.; Brooks, David H.
Using coordinated observations of a quiet coronal region, we study the intercalibration of the CDS and EIT instruments on board the Solar and Heliospheric Observatory (SOHO) and the Transition Region and Coronal Explorer (TRACE). We derive the differential emission measure (DEM) distribution from CDS spectral line intensities and convolve it with …
An Atlas of Hubble Space Telescope STIS Spectra of Seyfert Galaxies
Calzetti, D.; Storchi-Bergmann, T.; Brandt, C. H. +1 more
We present a compilation of spectra of 101 Seyfert galaxies obtained with the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS), covering the UV and/or optical spectral range. Information on all the available spectra have been collected in a Mastertable, which is a very useful tool for anyone interested in a quick glance at …
