Does Hubble Tension Signal a Breakdown in FLRW Cosmology?
Chethan Krishnan, Roya Mohayaee, Eoin Ó Colgáin +2
The tension between early and late Universe probes of the Hubble constant has motivated various new FLRW cosmologies. Here, we reanalyse the Hubble tension with a recent age of the…
A Dark Energy model from Generalized Proca Theory
Chao-Qiang Geng, Yan-Ting Hsu, Jhih-Rong Lu +1
We consider a specific dark energy model, which only includes the Lagrangian up to the cubic order in terms of the vector field self-interactions in the generalized Proca theory. W…
Can dark energy be dynamical?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Lu Yin
We highlight shortcomings of the dynamical dark energy (DDE) paradigm. For parametric models with equation of state (EOS), for a given function of redshift…
Observational Constraints on the Cosmology with Holographic Dark Fluid
Da Huang, Bum-Hoon Lee, Gansukh Tumurtushaa +2
We consider the holographic Friedman-Robertson-Walker (hFRW) universe on the 4-dimensional membrane embedded in the 5-dimensional bulk spacetime and fit the parameters with the obs…
Reducing the tension with generalized Proca theory
Antonio De Felice, Chao-Qiang Geng, Masroor C. Pookkillath +1
We investigate the cosmological viability of the generalized proca theory. We first implement the background and linear perturbation equations of motion in the Boltzmann code and t…
Running vacuum model in non-flat universe
Chao-Qiang Geng, Yan-Ting Hsu, Lu Yin +1
We investigate observational constraints on the running vacuum model (RVM) of in the spatially curved universe, where is the model parameter, corres…
