Abstract We show that a combined analysis of cosmic microwave background anisotropy power spectra obtained by the Planck satellite and luminosity distance data simultaneously excludes flat universe cosmological constant at 99% confidence level. These results hold separately when combining with three different sets: two determinations Hubble from Riess et al. Freedman al., Pantheon catalog high-...

In this paper, we have proposed a model of accelerating universe with binary mixture bulk viscous fluid and dark energy (DE) probed the parameters: present values Hubble’s constant [Formula: see text], equation state paper DE text] density parameter recent observational data (OHD) as well joint Pantheon compilation SN Ia OHD. Using cosmic chronometric technique, obtain by restricting our derive...

We explore the viability of three models in f(T,B) gravity using data from recent surveys based on cosmic chronometers, Pantheon set, and baryonic acoustic oscillation data. also assess consistency these set combinations with two important priors Hubble constant coming SH0ES Team measurements tip red giant branch respectively. These give highest lowest values cosmology independent studies. In g...

We test the mutual consistency between baryon acoustic oscillation measurements from eBOSS SDSS final release, as well Pantheon supernova compilation in a model independent fashion using Gaussian process regression. also their joint with $\Lambda$CDM model, fashion. use regression to reconstruct expansion history that is preferred by these two datasets. While this methodology finds no significa...

We study a power-law $F(R)$ gravity with an early dark energy term, that can describe both the early-time and late-time acceleration of Universe. confront this scenario recent observational data including Pantheon Type Ia supernovae, measurements Hubble parameter $H(z)$ (Cosmic Chronometers), from Baryon Acoustic Oscillations standard rulers Cosmic Microwave Background (CMB) radiation. The mode...

In the $\Lambda$CDM model, cosmological observations from late and recent universe reveal a puzzling $\sim 4.5\sigma$ tension in current rate of expansion. addition to various scenarios suggested resolve tension, non-parametric modeling may provide useful insights. this paper, we look at three well-known methods, smoothing method, genetic algorithm, Gaussian process. Considering these employ Hu...
