Accidental Inflation from Kähler Uplifting
Ido Ben-Dayan, Shenglin Jing, Alexander Westphal +1
We analyze the possibility of realizing inflation with a subsequent dS vacuum in the Kähler uplifting scenario. The inclusion of several quantum corrections to the 4d effective act…
Constraining the primordial power spectrum from SNIa lensing dispersion
Ido Ben-Dayan, Tigran Kalaydzhyan
The (absence of detecting) lensing dispersion of Supernovae type Ia (SNIa) can be used as a novel and extremely efficient probe of cosmology. In this preliminary example we analyze…
Average and dispersion of the luminosity-redshift relation in the concordance model
I. Ben-Dayan, M. Gasperini, G. Marozzi +2
Starting from the luminosity-redshift relation recently given up to second order in the Poisson gauge, we calculate the effects of the realistic stochastic background of perturbati…
