Euclid preparation: LXXXVII. Non-Gaussianity of 2-point statistics likelihood: Precise analysis of the matter power spectrum distribution
Euclid Collaboration, J. Bel, S. Gouyou Beauchamps +281
We investigate the non-Gaussian features in the distribution of the matter power spectrum multipoles. Using the COVMOS method, we generate 100\,000 mock realisations of dark matter…
The observed galaxy bispectrum from single-field inflation in the squeezed limit
Kazuya Koyama, Obinna Umeh, Roy Maartens +1
Using the consistency relation in Fourier space, we derive the observed galaxy bispectrum from single-field inflation in the squeezed limit, in which one of the three modes has a w…
The missing link: a nonlinear post-Friedmann framework for small and large scales
Irene Milillo, Daniele Bertacca, Marco Bruni +1
We present a nonlinear post-Friedmann framework for structure formation, generalizing to cosmology the weak-field (post-Minkowskian) approximation, unifying the treatment of small…
ISW effect in Unified Dark Matter Scalar Field Cosmologies: an analytical approach
Daniele Bertacca, Nicola Bartolo
We perform an analytical study of the Integrated Sachs-Wolfe (ISW) effect within the framework of Unified Dark Matter models based on a scalar field which aim at a unified descript…
