This paper studies both Formula omittedCDM and CDM models under the über gravity theory, named ü Formula omittedCDM and üCDM respectively. We report bounds over their parameter phase-space using ...several cosmological data, in particular, the recent Pantheon+ sample. Based on the joint analysis, the best fit value of the über characteristic parameter is Formula omitted and Formula omitted at 68% confidence level for ü Formula omittedCDM and üCDM respectively. Although über gravity can successfully mimics the cosmological constant, we find that the Formula omitted diagnostic suggests the Formula omitted tension is not alleviated. Finally, both models are statistically compared with Formula omittedCDM through the Akaike and Bayesian information criteria. Both über gravity models and Formula omittedCDM are equally preferred for most of the single samples, in particular, ü Formula omittedCDM is not rejected by the CMB data.

This paper studies both $\Lambda$CDM and CDM models under the \"uber gravity
theory, named \"u$\Lambda$CDM and \"uCDM respectively. We report bounds over
their parameter phase-space using several ...cosmological data, in particular, the
recent Pantheon+ sample. Based on the joint analysis, the best fit value of the
\"uber characteristic parameter is $z_\oplus = 0.046^{+0.047}_{-0.032}$ and
$z_\oplus = 1.382^{+0.020}_{-0.021}$ at 68\% confidence level for
\"u$\Lambda$CDM and \"uCDM respectively. Although \"uber gravity can
successfully mimics the cosmological constant, we find that the
$\mathbb{H}0(z)$ diagnostic suggests the $H_0$ tension is not alleviated.
Finally, both models are statistically compared with $\Lambda$CDM through the
Akaike and Bayesian information criteria. Both \"uber gravity models and
$\Lambda$CDM are equally preferred for most of the single samples, in
particular, \"u$\Lambda$CDM is not rejected by the CMB data. However, there is
strong evidence against them for the joint analysis.

We report bounds over their parameter phase-space using several ...cosmological data, in particular, the recent Pantheon+ sample. Based on the joint analysis, the best fit value of the \"uber characteristic parameter is \(z_\oplus = 0.046^{+0.047}_{-0.032}\) and \(z_\oplus = 1.382^{+0.020}_{-0.021}\) at 68\% confidence level for \"u\(\Lambda\)CDM and \"uCDM respectively. Although \"uber gravity can successfully mimics the cosmological constant, we find that the \(\mathbb{H}0(z)\) diagnostic suggests the \(H_0\) tension is not alleviated.
