Unified Dark Matter scalar field models with fast transition
Daniele Bertacca, Marco Bruni, Oliver F. Piattella +1
We investigate the general properties of Unified Dark Matter (UDM) scalar field models with Lagrangians with a non-canonical kinetic term, looking specifically for models that can…
High precision spectra at large redshift for dynamical DE cosmologies
S. A. Bonometto, L. Casarini, A. V. Maccio' +1
The next generation mass probes will investigate DE nature by measuring non-linear power spectra at various z, and comparing them with high precision simulations. Producing a compl…
High-precision spectra for dynamical Dark Energy cosmologies from constant-w models
Luciano Casarini
Spanning the whole functional space of cosmologies with any admissible DE state equations w(a) seems a need, in view of forthcoming observations, namely those aiming to provide a t…
High accuracy power spectra including baryonic physics in dynamical Dark Energy models
Luciano Casarini, Andrea V. Maccio', Silvio A. Bonometto +1
The next generation mass probes will obtain information on non--linear power spectra P(k,z) and their evolution, allowing us to investigate the nature of Dark Energy. To exploit su…
Large non-Gaussianities in the Effective Field Theory Approach to Single-Field Inflation: the Bispectrum
Nicola Bartolo, Matteo Fasiello, Sabino Matarrese +1
The methods of effective field theory are used to study generic theories of inflation with a single inflaton field and to perform a general analysis of the associated non-Gaussiani…
A circular polarimeter for the Cosmic Microwave Background
Massimo Giovannini
A primordial degree of circular polarization of the Cosmic Microwave Background is not observationally excluded. The hypothesis of primordial dichroism can be quantitatively falsif…
