Quasar -- CIV forest cross-correlation with SDSS DR12
Satya Gontcho A Gontcho, Jordi Miralda-Escudé, Andreu Font-Ribera +3
We present a new determination of the large-scale clustering of the CIV forest (i.e., the absorption due to all CIV absorbers) using its cross-correlation with quasars in the Sloan…
The SDSS-DR12 large-scale cross-correlation of Damped Lyman Alpha Systems with the Lyman Alpha Forest
Ignasi Pérez-Ràfols, Andreu Font-Ribera, Jordi Miralda-Escudé +9
We present a measurement of the DLA mean bias from the cross-correlation of DLA and the Ly forest, updating earlier results of Font-Ribera et al. 2012 with the final BOSS Data R…
Baryon acoustic oscillations from the complete SDSS-III Ly-quasar cross-correlation function at
Hélion du Mas des Bourboux, Jean-Marc Le Goff, Michael Blomqvist +22
We present a measurement of baryon acoustic oscillations (BAO) in the cross-correlation of quasars with the Ly-forest flux-transmission at a mean redshift . The measurem…
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
Measurement of BAO correlations at with SDSS DR12 \lya-Forests
Julian E. Bautista, Nicolás G. Busca, Julien Guy +24
We use flux-transmission correlations in \Lya forests to measure the imprint of baryon acoustic oscillations (BAO). The study uses spectra of 157,783 quasars in the redshift range…
