Host galaxies of z ~ 4.7 QSOs
J. B. Hutchings
2 micron broad- and narrow-band imaging with the Gemini-N telescope of five z~4.7 QSOs, has resolved both the host galaxies and [O II] emission-line gas. The resolved fluxes of the…
The Peculiar Nebula Simeis 57: I. Ionized Gas and Dust Extinction
F. P. Israel, M. Kloppenburg, P. E. Dewdney +1
We present high resolution radio continuum maps of the Galactic nebula Simeis 57 (= HS 191 = G 80.3+4.7) made with the WSRT and the DRAObservatory at frequencies of 609, 1412 and 1…
Carbon Abundances of Faint Stars in M13 - Evidence for Two Abundance Altering Mechanisms
Michael M. Briley, Judith G. Cohen, Peter B. Stetson
We present an analysis of CH band strengths in Keck LRIS spectra of a sample of 81 stars in M13 within 2 magnitudes of the main-sequence turnoff. The subgiants clearly exhibit a su…
The 1.6um Bump as a Photometric Redshift Indicator
Marcin Sawicki
I describe the principle of using the 1.6um H- spectral feature as a photometric redshift indicator and demonstrate that the technique holds promise by successfully recovering the…
Chemical Abundances in Twelve Red Giants of the Large Magellanic Cloud from High-Resolution Infrared Spectroscopy
V. V. Smith, K. H. Hinkle, K. Cunha +10
High-resolution infrared spectra (R=50,000) have been obtained for twelve red-giant members of the LMC with the Gemini South 8.3-meter telescope plus Phoenix spectrometer. Quantita…
Evolution of Galaxy Morphology
Sidney van den Bergh
A strictly empirical review is given of presently available data on the evolution of galaxy morphology. From HST observations of distant galaxies and ground-based observations of n…
