Constraints on dark radiation from cosmological probes
Graziano Rossi, Christophe Yeche, Nathalie Palanque-Delabrouille +1
We present joint constraints on the number of effective neutrino species N_eff and the sum of neutrino masses M_nu, based on a technique which exploits the full information contain…
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…
Constraint on neutrino masses from SDSS-III/BOSS Ly forest and other cosmological probes
Nathalie Palanque-Delabrouille, Christophe Yèche, Julien Lesgourgues +11
We present constraints on the parameters of the CDM cosmological model in the presence of massive neutrinos, using the one-dimensional Ly forest power spectrum obtained with…
The 0.1<z<1.65 evolution of the bright end of the [OII] luminosity function
Johan Comparat, Johan Richard, Jean-Paul Kneib +33
We present the [OII] 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-calib…
IGM Constraints from the SDSS-III/BOSS DR9 Ly-alpha Forest Flux Probability Distribution Function
Khee-Gan Lee, Joseph P. Hennawi, David N. Spergel +13
The Ly forest transmission probability distribution function (PDF) is an established probe of the intergalactic medium (IGM) astrophysics, especially the temperature-density rel…
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…
