The onion universe: all sky lightcone simulations in spherical shells
P. Fosalba, E. Gaztanaga, F. Castander +1
Galaxy surveys provide a large-scale view of the universe that typically has a limited line-of-sight or redshift resolution. The lack of radial accuracy in these surveys can be mod…
Cross-correlation of WMAP 3rd year and the SDSS DR4 galaxy survey: new evidence for Dark Energy
A. Cabre, E. Gaztanaga, M. Manera +2
We cross-correlate the third-year WMAP data with galaxy samples extracted from the SDSS DR4 (SDSS4) covering 13% of the sky, increasing by a factor of 3.7 the volume sampled in pre…
Cluster number counts dependence on dark energy inhomogeneities and coupling to dark matter
M. Manera, D. F. Mota
Cluster number counts can be used to test dark energy models. We investigate dark energy candidates which are coupled to dark matter. We analyze the cluster number counts dependenc…
Large scale structure and the generalised Chaplygin gas as dark energy
T. Multamaki, M. Manera, E. Gaztanaga
The growth of large scale structure is studied in a universe containing both cold dark matter (CDM) and generalized Chaplygin gas (GCg). GCg is assumed to contribute only to the ba…
Large scale structure in non-standard cosmologies
T. Multamaki, E. Gaztanaga, M. Manera
We study the growth of large scale structure in two recently proposed non-standard cosmological models: the brane induced gravity model of Dvali, Gabadadze and Porrati (DGP) and th…
