5σ tension between Planck cosmic microwave background and eBOSS Lyman-alpha forest and constraints on physics beyond ΛCDM by Keir K. Rogers, Vivian Poulin

“…Model extensions can alleviate this tension: running in the tilt of the primordial power spectrum (α_{s}∼−0.01); a fraction ∼(1−5)% of ultralight axion dark matter (DM) with particle mass ∼10^{−25} eV or warm DM with mass ∼10 eV. The new Dark Energy Spectroscopic Instrument survey, coupled with high-accuracy modeling, will help distinguish the source of this discrepancy.…”

A Cosmological Scaling Relation for Describing the Late Time Dynamics by Gerardo Cristofano, Orlando Luongo

“…Under this hypothesis, the scaling relation is interpreted as a thermodynamic modification able to describe the cosmological dynamics at late times. In this scheme, dark energy emerges, as a consequence of assuming the validity of our scale relation. …”

Toy Models of Universe with an Effective Varying Λ-Term in Lyra Manifold by Martiros Khurshudyan

“…Research on the accelerated expansion of our Universe captures a lot of attention. The dark energy (DE) is a way to explain it. In this paper we will consider scalar field quintessence DE with ωDE>-1 EoS, where the dynamics of the DE models related to the dynamics of the scalar field. …”

Constraints on the Dark Side of the Universe and Observational Hubble Parameter Data by Tong-Jie Zhang, Cong Ma, Tian Lan

“…This paper is a review on the observational Hubble parameter data that have gained increasing attention in recent years for their illuminating power on the dark side of the universe: the dark matter, dark energy, and the dark age. Currently, there are two major methods of independent observational H(z) measurement, which we summarize as the “differential age method” and the “radial BAO size method.” …”

Dynamical system analysis for extended f(P) gravity coupled with scalar field by Ratul Mandal, Ujjal Debnath, Anirudh Pradhan

“…$$f(P)=\alpha P +\beta P^2$$ f ( P ) = α P + β P 2 , where $$\alpha $$ α and $$\beta $$ β are constant parameters. As an additional dark energy component, we take a canonical scalar field $$\phi $$ ϕ , and several types of interaction between the dark components are considered. …”
