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

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

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 ...

The 0.1 < z < 1.65 evolution of the bright end of the [O II] luminosity function

Johan Richard, Johan Comparat, Jean-Paul Richard Kneib, Timothée Guy Olivier Delubac, Jun Ma, David Schlegel, Zhenyu Wu

We present the [O II] (lambda lambda 3729; 3726) luminosity function measured in the redshift range 0.1 < z < 1.65 with unprecedented depth and accuracy. Our measurements are based on medium resolution flux-calibrated spectra of emission line galaxies with ...

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

Johan Comparat, Pierre Laurent, 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 Eleventh And Twelfth Data Releases Of The Sloan Digital Sky Survey: Final Data From Sdss-Iii

Johan Comparat, Pierre Laurent, Jean-Paul Richard Kneib, Yuguang Chen, Timothée Guy Olivier Delubac, Jian Liu, David Schlegel, Yue Shen, 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 Tenth Data Release Of The Sloan Digital Sky Survey: First Spectroscopic Data From The Sdss-Iii Apache Point Observatory Galactic Evolution Experiment

Johan Comparat, Arnaud Borde, Bo Ma, Jean-Paul Richard Kneib, Timothée Guy Olivier Delubac, David Schlegel, Ginevra Favole, Yue Shen, Zheng Zheng

The Sloan Digital Sky Survey (SDSS) has been in operation since 2000 April. This paper presents the Tenth Public Data Release (DR10) from its current incarnation, SDSS-III. This data release includes the first spectroscopic data from the Apache Point Obser ...

Weak lensing mass map and peak statistics in Canada-France-Hawaii Telescope Stripe 82 survey

Georges Meylan, Frédéric Courbin, Johan Comparat, Jean-Paul Richard Kneib, Huanyuan Shan

We present a weak lensing mass map covering similar to 124 deg(2) of the Canada-France-Hawaii Telescope Stripe 82 Survey (CS82). We study the statistics of rare peaks in the map, including peak abundance, the peak-peak correlation functions and the tangent ...

Measuring galaxy [OII] emission line doublet with future ground-based wide-field spectroscopic surveys (Research Note)

Johan Comparat, Jean-Paul Richard Kneib, David Schlegel

The next generation of wide-field spectroscopic redshift surveys will map the large-scale galaxy distribution in the redshift range 0.7

EDP Sciences2013

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

Johan Comparat, Jean-Paul Richard Kneib, Huanyuan Shan, David Schlegel

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 ...
