Optical Emission Band Morphologies of the Red Rectangle
Uma P. Vijh, Adolf N. Witt, Donald G. York +3
We present narrow-band images of the Red Rectangle (RR) nebula which reveal the distinct morphologies of this intriguing nebula in different optical emission bands. The morphology…
Prototype development of the Integral-Field unit for VIRUS
Andreas Kelz, Svend M. Bauer, Frank Grupp +6
VIRUS is a planned integral-field instrument for the Hobby-Eberly Telescope (HET). In order to achieve a large field-of-view and high grasp at reasonable costs, the approach is to…
Ultraviolet-Bright, High-Redshift ULIRGS
James W. Colbert, Harry Teplitz, Paul Francis +3
We present Spitzer Space Telescope observations of the z=2.38 lya-emitter over-density associated with galaxy cluster J2143-4423, the largest known structure (110 Mpc) above z=2. W…
A Fabry-Perot Imaging Search for Lyman-alpha Emission in Quasar Absorbers at z ~ 2.4
V. P. Kulkarni, B. E. Woodgate, D. G. York +4
We have carried out a deep narrow-band imaging survey of six fields with heavy-element quasar absorption lines, using the Goddard Fabry-Perot (FP) system at the Apache Point Observ…
The Evolution of Damped Lyman-alpha Absorbers: Metallicities and Star Formation Rates
Varsha P. Kulkarni, Donald G. York, James T. Lauroesch +8
The damped Lyman-alpha (DLA) and sub-DLA quasar absorption lines provide powerful probes of the evolution of metals, gas, and stars in galaxies. One major obstacle in trying to und…
The Distribution of Ly-alpha-Emitting Galaxies at z=2.38: Paper 2, Spectroscopy
Paul J. Francis, Povilas Palunas, Harry I. Teplitz +2
In Paper 1 of this series we identified an 80 co-moving Mpc filament of candidate Lyman-alpha emitting galaxies at redshift 2.38. In this paper we present spectroscopy of the 37 ga…
