The nature and evolution of the highly ionized near-zones in the absorption spectra of z~6 quasars
James S. Bolton, Martin G. Haehnelt
We use state-of-the-art hydrodynamical simulations combined with a 1D radiative transfer code to assess the extent to which the highly ionized regions observed close to z~6 quasars…
Numerical Simulations of the Lyman-alpha forest - A comparison of Gadget-2 and Enzo
John A. Regan, Martin G. Haehnelt, Matteo Viel
We compare simulations of the Lyman-alpha forest performed with two different hydrodynamical codes, Gadget-2 and Enzo. A comparison of the dark matter power spectrum for simulation…
Transverse and longitudinal correlation functions in the Intergalactic Medium from 32 close pairs of high-redshift quasars
F. Coppolani, P. Petitjean, F. Stoehr +6
We present the transverse flux correlation function of the Lyman-alpha forest in quasar absorption spectra at z~2.1 from VLT-FORS and VLT-UVES observations of a total of 32 pairs o…
The Lyman-alpha forest and WMAP year three
Matteo Viel, Martin G. Haehnelt, Antony Lewis
A combined analysis of Cosmic Microwave Background (CMB) and Lyman-a forest data allows to constrain the matter power spectrum from small scales of about 1 Mpc/h all the way to the…
Can sterile neutrinos be ruled out as warm dark matter candidates?
Matteo Viel, Julien Lesgourgues, Martin G. Haehnelt +2
We present constraints on the mass of warm dark matter (WDM) particles from a combined analysis of the matter power spectrum inferred from the Sloan Digital Sky Survey \lya flux po…
