“…2) There are ongoing efforts to solve the H 0 and S 8 problems by modifying the standard ΛCDM model [11,12]. Some of these efforts require a significant re-interpretation of the available data, resulting in much higher values of n s , all the way up to the Harris-Zeldovich value n s = 1, see [13,14] and references therein.…”

We construct α-attractor versions of hybrid inflation models. In these models, the potential of the inflaton field ϕ is uplifted by the potential of the second field χ. This uplifting ends due to a tachyonic instability with respect to the field χ, which appears when ϕ becomes smaller than some critical value ϕ c . In the large N limit, these models have the standard universal α-attractor predictions. In particular, n s = 1 − 2 N for the exponential attractors. However, in some special cases the large N limit is reached only beyond the horizon, for N 60. This may change predictions for the cosmological observations. For any fixed N , in the limit of large uplift V up , or in the limit of large ϕ c , we find another attractor prediction, n s = 1. By changing the parameters V up and ϕ c one can continuously interpolate between the two attractor predictions n s = 1 − 2 N and n s = 1.

“…Although the flat ΛCDM model makes predictions consistent with most observations (see, e.g. Scolnic et al 2018;Yu et al 2018;Planck Collaboration 2020;eBOSS Collaboration 2021), it has some potential observational discrepancies (Di Valentino et al 2021b;Perivolaropoulos & Skara 2021;Abdalla et al 2022) that motivate us to also study dynamical dark energy models as well as models with non-zero spatial curvature.…”

We use 38 C quasar (QSO) reverberation-measured observations, which span eight orders of magnitude in luminosity and the redshift range 0.001064 ≤ 𝑧 ≤ 3.368, to simultaneously constrain cosmological-model and QSO radius-luminosity (𝑅 − 𝐿) relation parameters in six cosmological models, using an improved technique that more correctly accounts for the asymmetric errors bars of the time-lag measurements. We find that 𝑅 − 𝐿 relation parameters are independent of the cosmological models used in the analysis and so the 𝑅 − 𝐿 relation can be used to standardize the C QSOs. The C QSO cosmological constraints are consistent with those from Mg QSOs, allowing us to derive joint C + Mg QSO cosmological constraints which are consistent with currently accelerated cosmological expansion, as well as consistent with cosmological constraints derived using better-established baryon acoustic oscillation (BAO) and Hubble parameter [𝐻 (𝑧)] measurements. When jointly analyzed with 𝐻 (𝑧) + BAO data, current C + Mg QSO data mildly tighten current 𝐻 (𝑧) + BAO data cosmological constraints.

“…The recent indication of a statistical tension [1][2][3][4] in value of the Hubble constant H 0 has prompted a reassessment of possible modifications beyond standard vanilla ΛCDM. While the H 0 problem may be the result of systematics, the mismatch in reported values of the Hubble constant has been reported by a number of surveys indicating a more serious nature to the issue.…”

We explore the viability of three models in f (T, B) gravity using data from recent surveys based on cosmic chronometers, the Pantheon data set, and baryonic acoustic oscillation data. We also assess the consistency of these models and data set combinations with two important priors on the Hubble constant coming from the SH0ES Team and measurements using the tip of the red giant branch respectively. These give the highest and lowest values of the Hubble constant coming from cosmology independent studies. In general, our analysis does provide a more consistent fit for the late time data being analyzed. However, each model does include an additional model parameter in comparison with the concordance model. We close the analysis with a comparative analysis in which each model, data set and Hubble constant prior combination are cross-analyzed against each other.
