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…
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…
Comment on "Cosmic Microwave Background Constraints Cast a Shadow On Continuous Spontaneous Localization Models"
Gabriel R. Bengochea, Gabriel Leon, Philip Pearle +1
In a recent paper [J. Martin and V. Vennin, Phys. Rev. Lett. 124, 080402 (2020)] it was argued that, for most natural choices, the direct application of the continuous spontaneous…
Generation of inflationary perturbations in the continuous spontaneous localization model: The second order power spectrum
Gabriel Leon, Maria Pia Piccirilli
Cosmic inflation, which describes an accelerated expansion of the early Universe, yields the most successful predictions regarding temperature anisotropies in the cosmic microwave…
Origin of structure: Statistical characterization of the primordial density fluctuations and the collapse of the wave function
Gabriel Leon, Daniel Sudarsky
The statistical properties of the primordial density perturbations has been considered in the past decade as a powerful probe of the physical processes taking place in the early un…
