Lensing and time-delay contributions to galaxy correlations
Alvise Raccanelli, Daniele Bertacca, Roy Maartens +2
Galaxy clustering on very large scales can be probed via the 2-point correlation function in the general case of wide and deep separations, including all the lightcone and relativi…
Large-scale 3D galaxy correlation function and non-Gaussianity
Alvise Raccanelli, Daniele Bertacca, Olivier Dore +1
We investigate the properties of the 2-point galaxy correlation function at very large scales, including all geometric and local relativistic effects -- wide-angle effects, redshif…
Matter bispectrum in cubic Galileon cosmologies
Nicola Bartolo, Emilio Bellini, Daniele Bertacca +1
In this paper we obtain the bispectrum of dark matter density perturbations in the frame of covariant cubic Galileon theories. This result is obtained by means of a semi-analytic a…
