Primordial inflation explains why the universe is accelerating today
Edward W. Kolb, Sabino Matarrese, Alessio Notari +1
We propose an explanation for the present accelerated expansion of the universe that does not invoke dark energy or a modification of gravity and is firmly rooted in inflationary c…
Unified treatment of cosmological perturbations from super-horizon to small scales
Carmelita Carbone, Sabino Matarrese
We study the evolution of cosmological perturbations, using a hybrid approximation scheme which upgrades the weak-field limit of Einstein's field equations to account for post-Newt…
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-…
The bias of galaxies and the density of the universe from the 2dF galaxy redshift survey
Licia Verde, Alan F. Heavens, Will J. Percival +1
By studying the bispectrum of the galaxy distribution in the 2dF galaxy redhsift survey (2dFGRS), we have shown that 2dFGRS galaxies are unbiased tracers of the mass distribution.…
Predicting the Clustering of X-Ray Clusters
Lauro Moscardini, Sabino Matarrese, Francesco Lucchin +2
We present a theoretical model which aims at predicting the clustering properties of X-ray clusters in flux-limited surveys for different cosmological scenarios. The model uses the…
The stochastic gravitational-wave background produced by non-linear cosmological perturbations
Sabino Matarrese, Silvia Mollerach
The cosmological stochastic gravitational-wave background produced by the mildly non-linear evolution of density fluctuations is analyzed, in the frame of an Einstein-de Sitter mod…
