Constraints on primordial black holes for nonstandard cosmologies
Tadeo D. Gomez-Aguilar, Luis E. Padilla, Encieh Erfani +1
We study how the bounds on the abundance of Primordial Black Holes (PBHs) and the constraints on power spectrum are modified if a non-standard evolution phase takes place between t…
Solution for cosmological observables in the Starobinsky model of inflation
Gabriel German, Juan Carlos Hidalgo, Luis E. Padilla
This paper focuses on the Starobinsky model of inflation. We derive solutions for various cosmological observables, such as the scalar spectral index , the tensor-to-scalar ra…
Growth rate of spherical voids with non-comoving Dark Matter and Baryons
Fernando A. Pizaña, Juan Carlos Hidalgo, Ismael Delgado Gaspar +1
We present numerical solutions to Einstein's equations describing large spherical cosmic voids constituted by two components; dark matter and baryons, with a non-vanishing initial…
Constraining inflationary potentials with inflaton PBHs
Luis E. Padilla, Juan Carlos Hidalgo, Gabriel German
If, after primordial inflation, the universe undergoes a relatively long reheating period, it could present a phase of matter domination supported by the oscillating inflaton field…
