How cold is cold dark matter? Small scales constraints from the flux power spectrum of the high-redshift Lyman-alpha forest
M. Viel, G. D. Becker, J. S. Bolton +3
We present constraints on the mass of warm dark matter (WDM) particles derived from the Lyman-alpha flux power spectrum of 55 high- resolution HIRES spectra at 2.0 < z < 6.4. From…
Cosmic reionization in a dynamic quintessence cosmology
D. Crociani, M. Viel, L. Moscardini +2
In this paper we investigate the effects that a dynamic dark energy component dominant in the universe at late epochs has on reionization. We follow the evolution of HII regions wi…
A combined analysis of 3D Weak Lensing, Lyman-alpha forest and WMAP year three data
J. Lesgourgues, M. Viel, M. G. Haehnelt +1
We present constraints on the amplitude and shape of the matter power spectrum and the density of dark matter within the framework of a standard LambdaCDM model. We use a Markov Ch…
The Lyman-alpha forest according to LUQAS
M. Viel, M. Haehnelt, T. -S. Kim +6
We use the LUQAS sample of 27 high resolution, high signal-to-noise QSO absorption spectra (Kim et al. 2004) and the results from Croft et al. (2002) together with a suite of high-…
Cosmology with the lyman-alpha forest in the WMAP era
Matteo Viel
In the WMAP era of high precision cosmology an accurate determination of the matter power spectrum from lyman-alpha forest data becomes crucial. When combining the matter power spe…
