Baryon acoustic oscillations from the cross-correlation of Ly absorption and quasars in eBOSS DR14
Michael Blomqvist, Hélion du Mas des Bourboux, Nicolás G. Busca +15
We present a measurement of the baryon acoustic oscillation (BAO) scale at redshift from the three-dimensional correlation of Lyman- (Ly) forest absorption and quasa…
Baryon acoustic oscillations at z = 2.34 from the correlations of Ly absorption in eBOSS DR14
Victoria de Sainte Agathe, Christophe Balland, Hélion du Mas des Bourboux +16
We measure the imprint of primordial baryon acoustic oscillations (BAO) in the correlation function of Ly absorption in quasar spectra from the Baryon Oscillation Spectroscopic…
Spectroscopic QUasar Extractor and redshift (z) EstimatorSQUEzE I: Methodology
Ignasi Pérez-Ràfols, Matthew M. Pieri, Michael Blomqvist +2
We present SQUEzE, a software package to classify quasar spectra and estimate their redshifts. SQUEzE is a random forest classifier operating on the parameters of candidate emissio…
The extended Baryon Oscillation Spectroscopic Survey: measuring the cross-correlation between the MgII flux transmission field and quasars and galaxies at
Hélion du Mas des Bourboux, Kyle S. Dawson, Nicolás G. Busca +12
We present the first attempt at measuring the baryonic acoustic oscillations (BAO) in the large scale cross-correlation between the magnesium-II doublet (MgII) flux transmission fi…
