Primordial gravitational waves and the H0-tension problem
Leila L. Graef, Micol Benetti, Jailson S. Alcaniz
We analyse the H0-tension problem in the context of models of the early universe that predict a blue tilted spectrum of primordial gravitational waves (GW's). By considering the GW…
Back-Reaction of Super-Hubble Cosmological Perturbations Beyond Perturbation Theory
Robert Brandenberger, Leila L. Graef, Giovanni Marozzi +1
We discuss the effect of super-Hubble cosmological fluctuations on the locally measured Hubble expansion rate. We consider a large bare cosmological constant in the early universe…
Probability of Warm Inflation in Loop Quantum Cosmology
L. L. Graef, Rudnei O. Ramos
Warm inflation is analyzed in the context of Loop Quantum Cosmology (LQC). The bounce in LQC provides a mean through which a Liouville measure can be defined, which has been used p…
