Accelerated expansion and matter creation

TL;DR

This paper introduces cosmological models incorporating matter creation, unifying dark matter and dark energy without exotic equations of state, thereby addressing the cosmic coincidence problem.

Contribution

It presents models that account for particle number variation, providing a unified explanation for dark matter and dark energy.

Findings

Models successfully explain accelerated expansion

Unifies dark matter and dark energy without exotic assumptions

Addresses the cosmic coincidence problem

Abstract

A set of cosmological models that takes into account the variation of the particle number is presented. In this context both dark matter and dark energy can be explained using a single component, without assuming any exotic equation of state, solving directly the cosmic coincidence problem.
