Effects of the modification of gravity on the production of primordial black holes
Sergio Andres Vallejo-Pena, Antonio Enea Romano
The enhancement of the spectrum of primordial comoving curvature perturbation can induce the production of primordial black holes (PBH) which could account for part of present…
Coordinate independent approach to the calculation of the effects of local structure on the luminosity distance
Sergio Andrés Vallejo-Peña, Antonio Enea Romano
Local structure can have important effects on luminosity distance observations, which could for example affect the local estimation of the Hubble constant based on low red-shift ty…
Are primordial black holes produced by entropy perturbations in single field inflationary models?
Sergio Andrés Vallejo-Peña, Antonio Enea Romano
We show that in single field inflationary models the super-horizon evolution of curvature perturbations on comoving slices , which can cause the production of primordi…
