Limits on Reddening and Gas-to-Dust Ratios for Seven Intermediate Redshift Damped Ly-alpha Absorbers from Diffuse Interstellar Bands
Brandon Lawton, Christopher W. Churchill, Brian A. York +5
We present equivalent width measurements and limits of six diffuse interstellar bands (DIBs) in seven damped Ly-alpha absorbers (DLAs) over the redshift range 0.091<z<0.524, sampli…
Searching for the Precursors of Life in External Galaxies
B. Lawton, C. W. Churchill, B. A. York +5
Are the organic molecules crucial for life on Earth abundant in early-epoch galaxies? To address this, we searched for organic molecules in extragalactic sources via their absorpti…
Detection of Diffuse Interstellar Bands in the z=0.5 Damped Lyman alpha system towards AO 0235+164
Brian A. York, Sara L. Ellison, Brandon Lawton +4
We report the first detection of the 5705 and 5780 A Diffuse Interstellar Bands (DIBs) in a moderate redshift Damped Lyman alpha (DLA) system. We measure a rest frame equivalent wi…
A Search For Organic Molecules in Intermediate Redshift DLAs
Brandon Lawton, Brian York, Sara L. Ellison +3
There has been a renewed interest in searching for diffuse interstellar bands (DIBs) due to their probable connection to organic molecules and, thus, their possible link to life in…
Cataclysmic Variables from SDSS II. The Second Year
Paula Szkody, Oliver Fraser, Nicole Silvestri +18
The first full year of operation following the commissioning year of the Sloan Digital Sky Survey has revealed a wide variety of newly discovered cataclysmic variables. We show the…
