The tension between the value of the Hubble constant H_0 H 0 determined from local
supernovae data and the one inferred from the cosmic microwave background based on the …

The eternal inflation problem continues to be considered one of standard's cosmology most
serious shortcomings. This arises when one considers the effects of" quantum fluctuations" …

Unimodular gravity is an alternative theory of gravity to general relativity. The gravitational
field equations are given by the trace-free version of Einstein's field equations. Due to the …

Recently, based on swampland considerations in string theory, the (no) eternal inflation
principle has been put forward. The natural question arises whether similar conditions hold …

The inflationary paradigm is extremely successful regarding predictions of temperature
anisotropies in the CMB. However, inflation also makes predictions for a CMB B-mode …

Space-time quantum contributions to the classical Einstein equations of General Relativity
are determined. The theoretical background is provided by the non-perturbative theory of …

Cosmic inflation, which describes an accelerated expansion of the early Universe, yields the
most successful predictions regarding temperature anisotropies in the cosmic microwave …

We calculate the primordial power spectrum of tensor perturbations, within the emergent
universe scenario, incorporating a version of the Continuous Spontaneous Localization …

We propose a novel realization for the natural extrapolation of the continuous spontaneous
localization (CSL) model, in order to account for the origin of primordial inhomogeneities …

In this work we analyze how the spectrum of primordial scalar perturbations is modified,
within the emergent universe scenario, when a particular version of the Continuous …
