Confronting dark energy models mimicking CDM epoch with observational constraints: future cosmological perturbations decay or future Rip?
Artyom V. Astashenok, Sergei D. Odintsov
We confront dark energy models which are currently similar to CDM theory with observational data which include the SNe data, matter density perturbations and baryon acoustic osc…
Variety of cosmic acceleration models from massive bigravity
Shin'ichi Nojiri, Sergei D. Odintsov, Norihito Shirai
We study the accelerating cosmology in massive bigravity via the reconstruction scheme. The consistent solution of the FRW equations is presented: it includes Big and Little…
Future singularities and Teleparallelism in Loop Quantum Cosmology
Kazuharu Bamba, Jaume de Haro, Sergei D. Odintsov
We demonstrate how holonomy corrections in loop quantum cosmology (LQC) prevent the Big Rip singularity by introducing a quadratic modification in terms of the energy density i…
Ghost-free bigravity and accelerating cosmology
Shin'ichi Nojiri, Sergei D. Odintsov
We propose a bigravity analogue of the gravity. Our construction is based on recent ghost-free massive bigravity where additional scalar fields are added and the correspondi…
Turbulence and Little Rip Cosmology
I. Brevik, R. Myrzakulov, S. Nojiri +1
A variety of conditions is considered under which the cosmic dark fluid may be able to develop a future Big Rip or Little Rip singularity. Both one-component and two-component mode…
Cosmic history of viable exponential gravity: Equation of state oscillations and growth index from inflation to dark energy era
Kazuharu Bamba, Antonio Lopez-Revelles, R. Myrzakulov +2
A generic feature of viable gravity is investigated: It is demonstrated that during the matter dominated era the large frequency oscillations of the effective dark energy ma…
