TL;DR: In this paper , the authors focus on the 5.0σ tension between the Planck CMB estimate of the Hubble constant H0 and the SH0ES collaboration measurements and discuss the importance of trying to fit a full array of data with a single model.

TL;DR: In this article, loop quantum cosmology (LQC) with a small cosmological constant is used to model a universe moving along an ellipse, which prevents singularities like the big bang or the big rip, in the phase space.

TL;DR: In this paper, a detailed analytical and numerical study when holonomy corrections are taken into account in both Jordan and Einstein frames obtaining, in Jordan frame, a dynamics which differs qualitatively, at early times, from the one of the original model.

TL;DR: In this article, a fine set of parameters is introduced for bouncing cosmologies in order to describe the nearly matter-dominated phase, and which play the same role that the usual slow-roll parameters play in inflationary cosmology.

TL;DR: In this article, the authors considered the matter bounce scenario in Loop Quantum Cosmology (LQC) for physical potentials that at early times provide a nearly matter dominated Universe in the contracting phase, having a reheating mechanism in the expanding phase, and finally at late times leading to the current cosmic acceleration.
