Robustness of cosmic neutrino background detection in the cosmic microwave background
Benjamin Audren, Emilio Bellini, Antonio J. Cuesta +9
The existence of a cosmic neutrino background can be probed indirectly by CMB experiments, not only by measuring the background density of radiation in the universe, but also by se…
Mock Quasar-Lyman-α Forest Data-sets for the SDSS-III Baryon Oscillation Spectroscopic Survey
Julian E. Bautista, Stephen Bailey, Andreu Font-Ribera +15
We describe mock data-sets generated to simulate the high-redshift quasar sample in Data Release 11 (DR11) of the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS). The mock…
Cosmological implications of baryon acoustic oscillation (BAO) measurements
Éric Aubourg, Stephen Bailey, Julian E. Bautista +90
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…
On the effect of the ionising background on the Lyα forest autocorrelation function
Satya Gontcho A Gontcho, Jordi Miralda-Escudé, Nicolás G. Busca
An analytical framework is presented to understand the effects of a fluctuating intensity of the cosmic ionising background on the correlations of the Lyα forest transmission fract…
Baryon Acoustic Oscillations in the Lyα forest of BOSS DR11 quasars
Timothée Delubac, Julian E. Bautista, Nicolás G. Busca +35
We report a detection of the baryon acoustic oscillation (BAO) feature in the flux-correlation function of the Lyα forest of high-redshift quasars with a statistical significance o…
