The incorporation of bulk viscosity process to General Relativity leads to the appearance of nonsingular backgrounds that, at early and late times, depict an accelerated universe. These backgrounds could be analytically calculated and mimicked, in the context of General Relativity, by a single scalar field whose potential could also be obtained analytically. We will show that, we can build viable backgrounds that, at early times, depict an inflationary universe leading to a power spectrum of cosmological perturbations which match with current observational data, and after leaving the inflationary phase, the universe suffers a phase transition needed to explain the reheating of the universe via gravitational particle production, and finally, at late times, it enters into the de Sitter phase that can explain the current cosmic acceleration.

  1. Scaling solutions in quintessential inflation

    gr-qc 2019-08 conditional novelty 5.0 of 10

    In quintessential inflation, the scalar field misses the scaling-solution attractor during radiation, so a single exponential tail can drive both inflation and dark energy.

  2. Inflationary Phenomenology of Einstein Gauss-Bonnet Gravity Compatible with GW170817

    gr-qc 2019-08 conditional novelty 4.0 of 10

    Einstein Gauss-Bonnet inflation can have gravitational wave speed equal to light speed and can match Planck 2018 data when the scalar-GB coupling satisfies \ddotξ = H\dotξ and the potential is a tuned power law.

  3. In the Realm of the Hubble tension $-$ a Review of Solutions

    astro-ph.CO 2021-03 unverdicted novelty 2.0 of 10

    A review summarizing the Hubble constant tension and proposed solutions from new physics that restore agreement between Planck CMB data and local H0 measurements within 1-2 sigma.
