The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
Velocity Segregation and Systematic Biases In Velocity Dispersion Estimates With the SPT-GMOS Spectroscopic Survey
Matthew. B. Bayliss, Kyle Zengo, Jonathan Ruel +15
The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocit…
The Gould's Belt Distances Survey (GOBELINS) I. Trigonometric parallax distances and depth of the Ophiuchus complex
Gisela N. Ortiz-León, Laurent Loinard, Marina A. Kounkel +14
We present the first results of the Gould's Belt Distances Survey (GOBELINS), a project aimed at measuring the proper motion and trigonometric parallax of a large sample of young s…
A Study of Quasar Selection in the Dark Energy Survey Supernova fields
S. S. Tie, P. Martini, D. Mudd +75
We present a study of quasar selection using the DES supernova fields. We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completenes…
Stellar Populations of Shell Galaxies
S. Carlsten, G. K. T. Hau, A. Zenteno
We present a study of the inner (out to 1 R) stellar populations of 9 shell galaxies. We derive stellar population parameters from long slit spectra by both…
