Recombination Ghosts in Littrow Configuration: Implications for Spectrographs Using Volume Phase Holographic Gratings
Eric B. Burgh, Matthew A. Bershady, Kyle B. Westfall +1
We report the discovery of optical ghosts generated when using Volume Phase Holographic (VPH) gratings in spectrographs employing the Littrow configuration. The ghost is caused by…
The metallicity extremes of the Sagittarius dSph using SALT spectroscopy of PNe
A. Kniazev, A. Zijlstra, E. Grebel +10
In this work we present the first spectroscopic results obtained with the Southern African Large Telescope (SALT) telescope during its perfomance-verification phase. We find that t…
The polar ring galaxy AM1934-563 revisited
N. Brosch, A. Kniazev, D. Buckley +8
We report long-slit spectroscopic observations of the dust-lane polar-ring galaxy AM1934-563 obtained with the Southern African Large Telescope (SALT) during its performance-verifi…
Direct Measurement of the Ratio of Carbon Monoxide to Molecular Hydrogen in the Diffuse Interstellar Medium
Eric B. Burgh, Kevin France, Stephan R. McCandliss
We have used archival far-ultraviolet spectra from observations made by HST/STIS and FUSE to determine the column densities and rotational excitation temperatures for CO and H2, re…
