Strongly Coupled Dark Energy Cosmologies yielding large mass Primordial Black Holes
S. A. Bonometto, R. Mainini, M. Mezzetti
Large primordial Black Hole (PBH) formation is enhanced if strongly coupled scalar and spinor fields ( and ) are a stable cosmic component since the primeval radiative expans…
Strongly Coupled Dark Energy with Warm dark matter vs. LCDM
Silvio A. Bonometto, Marino Mezzetti, Roberto Mainini
Cosmologies including strongly Coupled (SC) Dark Energy (DE) and Warm dark matter (SCDEW) are based on a conformally invariant (CI) attractor solution modifying the early radiative…
Strongly Coupled Cosmologies
S. A. Bonometto, M. Mezzetti, I. Musco +2
Models including an energy transfer from CDM to DE are widely considered in the literature, namely to allow DE a significant high-z density. Strongly Coupled cosmologies assume a m…
Sample variance in N--body simulations and impact on tomographic shear predictions
Luciano Casarini, Oliver Piattella, Silvio Bonometto +1
We study the effects of sample variance in N--body simulations, as a function of the size of the simulation box, namely in connection with predictions on tomographic shear spectra.…
Recovery of fluctuation spectrum evolution from tomographic shear spectra
Silvio A. Bonometto, Marino Mezzetti
Forthcoming large angle surveys are planned to obtain high precision tomographic shear data. In principle, they will allow us to recover the spectra of matter density fluctuation,…
Constraints on Dark Energy state equation with varying pivoting redshift
Dario Scovacricchi, Silvio A. Bonometto, Marino Mezzetti +1
We assume the DE state equations w(a) = w_0+w_a(a_p-a), and study the dependence of the constraints on w_0 and w_a coefficients on the pivoting redshift 1+z_p=1/a_p. Coefficients a…
