Clustering of quasars in SDSS-IV eBOSS: study of potential systematics and bias determination

Jean-Paul Richard Kneib, Johan Comparat, Pierre Laurent

We study the first year of the eBOSS quasar sample in the redshift range 0.9 < z < 2.2 which includes 68,772 homogeneously selected quasars. We show that the main source of systematics in the evaluation of the correlation function arises from inhomogeneiti ...

Exploring cosmic homogeneity with the BOSS DR12 galaxy sample

Timothée Guy Olivier Delubac, Pierre Laurent

In this study, we probe the transition to cosmic homogeneity in the Large Scale Structure (LSS) of the Universe using the CMASS galaxy sample of BOSS spectroscopic survey which covers the largest effective volume to date, 3 h(-3) Gpc(3) at 0.43
