The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: selecting emission line galaxies using the Fisher discriminant

Jian Wang, Jean-Paul Richard Kneib, Johan Comparat, Xiaoqing Zhou, Anand Stéphane Raichoor, Timothée Guy Olivier Delubac, Zhe Jiang

We present a new selection technique of producing spectroscopic target catalogues for massive spectroscopic surveys for cosmology. This work was conducted in the context of the extended Baryon Oscillation Spectroscopic Survey (eBOSS), which will use simila ...

The extended Baryon Oscillation Spectroscopic Survey: a cosmological forecast

Jean-Paul Richard Kneib, Johan Comparat, Timothée Guy Olivier Delubac, Yuting Wang, Hanyu Zhang

We present a science forecast for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) survey. Focusing on discrete tracers, we forecast the expected accuracy of the baryonic acoustic oscillation (BAO), the redshift-space distortion (RSD) measureme ...

The evolution of the [O II], H beta and [O III] emission line luminosity functions over the last nine billions years

Jean-Paul Richard Kneib, Johan Comparat, Anand Stéphane Raichoor, Jeffrey Newman, Timothée Guy Olivier Delubac, Johan Richard

Emission line galaxies are one of the main tracers of the large-scale structure to be targeted by the next-generation dark energy surveys. To provide a better understanding of the properties and statistics of these galaxies, we have collected spectroscopic ...

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

Jean-Paul Richard Kneib, Johan Comparat, 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 ...

Clustering properties of g-selected galaxies at z similar to 0.8

Jean-Paul Richard Kneib, Johan Comparat, David Schlegel, Timothée Guy Olivier Delubac, Ginevra Favole

Current and future large redshift surveys, as the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey (SDSS-IV/eBOSS) or the Dark Energy Spectroscopic Instrument (DESI), will use emission-line galaxies (ELGs) to probe cosmological ...

SDSS-IV eBOSS emission-line galaxy pilot survey

Yi Zhang, Jean-Paul Richard Kneib, Eduardo Sanchez, Zhirui Xu, Johan Comparat, Anand Stéphane Raichoor, David Schlegel, Timothée Guy Olivier Delubac

The Sloan Digital Sky Survey IV extended Baryonic Oscillation Spectroscopic Survey (SDSS-IV/eBOSS) will observe 195 000 emission-line galaxies (ELGs) to measure the baryonic acoustic oscillation (BAO) standard ruler at redshift 0.9. To test different ELG s ...

Cosmological implications of baryon acoustic oscillation measurements

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

We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave background (CMB) data and a recent reanalysis of Type Ia supernova (SN) data. In p ...

NEAR-ULTRAVIOLET SPECTROSCOPY OF STAR-FORMING GALAXIES FROM eBOSS: SIGNATURES OF UBIQUITOUS GALACTIC-SCALE OUTFLOWS

Jean-Paul Richard Kneib, Johan Comparat, Anand Stéphane Raichoor, Jeffrey Newman, Timothée Guy Olivier Delubac

We present rest-frame near-ultraviolet (NUV) spectroscopy of star-forming galaxies (SFGs) at 0.6 < z < 1.2 from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) in SDSS-IV. One of the eBOSS programs is to obtain 2 ''. (about 15 kpc) fiber spect ...

Baryon acoustic oscillations in the Lya forest of BOSS DR11 quasars

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

We report a detection of the baryon acoustic oscillation (BAO) feature in the flux-correlation function of the Ly alpha forest of high-redshift quasars with a statistical significance of five standard deviations. The study uses 137 562 quasars in the redsh ...

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

Jean-Paul Richard Kneib, Zheng Zheng, Johan Comparat, David Schlegel, Timothée Guy Olivier Delubac, Jian Liu, Yuguang Chen, Yue Shen, Pierre Laurent

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 ...
