Overview of the DESI Legacy Imaging Surveys

Jean-Paul Richard Kneib, Anand Stéphane Raichoor, David Schlegel, Huanyuan Shan, Timothée Guy Olivier Delubac, Elodie Marie Charlène Savary, Arjun Dey, Claudio Gorgoni, Zhou Xue

The DESI Legacy Imaging Surveys (http://legacysurvey.org/) are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Survey) that will jointly image approximate to 14,000 ...

Stochastic bias of colour-selected BAO tracers by joint clustering-weak lensing analysis

Jean-Paul Richard Kneib, David Schlegel, Huanyuan Shan

The baryon acoustic oscillation (BAO) feature in the two-point correlation function of galaxies supplies a standard ruler to probe the expansion history of the Universe. We study here several galaxy selection schemes, aiming at building an emission-line ga ...

The Sdss-Iv Extended Baryon Oscillation Spectroscopic Survey: Quasar Target Selection

Jean-Paul Richard Kneib, David Schlegel

As part of the Sloan Digital Sky Survey (SDSS) IV the extended Baryon Oscillation Spectroscopic Survey (eBOSS) will improve measurements of the cosmological distance scale by applying the Baryon Acoustic Oscillation (BAO) method to quasar samples. eBOSS wi ...

The Sdss-Iv Extended Baryon Oscillation Spectroscopic Survey: Luminous Red Galaxy Target Selection

Jean-Paul Richard Kneib, David Schlegel, Timothée Guy Olivier Delubac

We describe the algorithm used to select the luminous red galaxy (LRG) sample for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (SDSS-IV) using photometric data from both the SDSS and the Wide-field Infrare ...

The Eleventh And Twelfth Data Releases Of The Sloan Digital Sky Survey: Final Data From Sdss-Iii

Jean-Paul Richard Kneib, David Schlegel, Timothée Guy Olivier Delubac, Zheng Zheng

The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new near-infrared high-resolution spectrograp ...

The completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: large-scale structure catalogues and measurement of the isotropic BAO between redshift 0.6 and 1.1 for the Emission Line Galaxy

Jean-Paul Richard Kneib, Cheng Zhao, Anand Stéphane Raichoor, David Schlegel, Amélie Tamone, Arjun Dey, Claudio Gorgoni

We present the Emission Line Galaxy (ELG) sample of the extended Baryon Oscillation Spectroscopic Survey from the Sloan Digital Sky Survey IV Data Release 16. We describe the observations and redshift measurement for the 269 243 observed ELG spectra, and t ...
