Observational constraints on the second-order primordial power spectrum: Exploring a Continuous Spontaneous Localization inspired inflationary model
Maria Pia Piccirilli, Gabriel Leon
Inflation, a period of exponential expansion in the early Universe, is considered an important part of the standard CDM cosmological model, and plays a crucial role in explainin…
A clarification on prevailing misconceptions in unimodular gravity
Gabriel R. Bengochea, Gabriel Leon, Alejandro Perez +1
The traditional presentation of Unimodular Gravity (UG) consists on indicating that it is an alternative theory of gravity that restricts the generic diffeomorphism invariance of G…
Reconstruction of inflationary scenarios in non-conservative unimodular gravity
M. P. Piccirilli, G. León
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. D…
Emergent universe: tensor perturbations within the CSL framework
Octavio Palermo, Martín M. Ocampo, Gabriel R. Bengochea +1
We calculate the primordial power spectrum of tensor perturbations, within the emergent universe scenario, incorporating a version of the Continuous Spontaneous Localization (CSL)…
Inflation and the cosmological (not-so) constant in unimodular gravity
Gabriel Leon
We propose a mechanism for generating an inflationary phase in the early universe without resorting to any type of scalar field(s). Instead, this accelerated expansion is driven by…
Emergent universe revisited through the CSL theory
Gabriel R. Bengochea, María Pía Piccirilli, Gabriel León
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 Spontane…
