Euclid Definition Study Report
R. Laureijs, J. Amiaux, S. Arduini +216
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to…
A new method for the determination of the growth rate from galaxy redshift surveys
Adi Nusser, Enzo Branchini, Marc Davis
Given a redshift survey of galaxies with measurements of apparent magnitudes, we present a novel method for measuring the growth rate of cosmological linear perturbations. W…
A cross-correlation study of the Fermi-LAT -ray diffuse extragalactic signal
Jun-Qing Xia, Alessandro Cuoco, Enzo Branchini +2
In this work, starting from 21 months of data from the Fermi-Large Area Telescope, we derive maps of the residual isotropic gamma-ray emission, a relevant fraction of which is expe…
Bulk flows from galaxy luminosities: application to 2MASS redshift survey and forecast for next-generation datasets
Adi Nusser, Enzo Branchini, Marc Davis
We present a simple method for measuring cosmological bulk flows from large redshift surveys, based on the apparent dimming or brightening of galaxies due to their peculiar motion.…
Growth factor and galaxy bias from future redshift surveys: a study on parametrizations
Cinzia Di Porto, Luca Amendola, Enzo Branchini
Many experiments in the near future will test dark energy through its effects on the linear growth of matter perturbations. In this paper we discuss the constraints that future lar…
