Measurements of effective optical depth in the Ly forest from the BOSS DR12 Quasar sample
Vikrant Kamble, Kyle Dawson, Hélion du Mas des Bourboux +2
We measure the effective optical depth in the Lyman-alpha (Ly) forest using 40,035 quasar spectra from the Twelfth Data Release (DR12) of the Baryon Oscillation Spectroscopic S…
The extended Baryon Oscillation Spectroscopic Survey: measuring the cross-correlation between the MgII flux transmission field and quasars and galaxies at
Hélion du Mas des Bourboux, Kyle S. Dawson, Nicolás G. Busca +12
We present the first attempt at measuring the baryonic acoustic oscillations (BAO) in the large scale cross-correlation between the magnesium-II doublet (MgII) flux transmission fi…
Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies, and the Distant Universe
Michael R. Blanton, Matthew A. Bershady, Bela Abolfathi +350
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOG…
Spectral Evolution in High Redshift Quasars from the Final BOSS Sample
Trey W. Jensen, M. Vivek, Kyle S. Dawson +17
We report on the diversity in quasar spectra from the Baryon Oscillation Spectroscopic Survey. After filtering the spectra to mitigate selection effects and Malmquist bias associat…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Overview and Early Data
Kyle S. Dawson, Jean-Paul Kneib, Will J. Percival +143
The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will conduct novel cosmological observations using the BOSS spectrograph at Apache Point Observatory. Observations will…
