No-go guide for late-time solutions to the Hubble tension: Matter perturbations

نویسندگان

چکیده

The Hubble tension seems to be a crisis with $\sim5\sigma$ discrepancy between the most recent local distance ladder measurement from type Ia supernovae calibrated by Cepheids and global fitting constraint cosmic microwave background data. To narrow down possible late-time solutions tension, we have used in study [Phys. Rev. D 105, L021301 (2022)] an improved inverse method absolute measurements of expansion rate at high redshifts chronometer data, found no appealing evidence for new physics late time beyond $\Lambda$CDM model characterized parametrization based on age. In this paper, further investigate perspective including matter perturbation growth Independent dataset choices, parametrizations, diagnostic quantities ($S_8$ $S_{12}$), is strongly disfavored so that previous no-go guide strengthened.

Exact Solutions for Cosmological Perturbations with Collisionless Matter

All regular and singular cosmological perturbations in a radiation dominated Einsteinde Sitter Universe with collisionless particles can be found by a generalized power series ansatz. Although the study of cosmological perturbations has a long history [1], exact solutions in the linear regime are known for a few perfect fluid models only (see, e.g., [2]). Within a more fundamental description o...

Analytic Solutions for Cosmological Perturbations in Multi-dimensional Space-time * †

We obtain analytic solutions for the density contrast and the anisotropic pressure in a multi-dimensional FRW cosmology with collisionless, massless matter. These are compared with perturbations of a perfect fluid universe. To describe the metric perturbations we use manifest gauge invariant metric potentials. The matter perturbations are calculated by means of (automatically gauge invariant) f...

Super-Hubble Nonlinear Perturbations During Inflation

We show that the non-linear evolution of long wavelength perturbations may be important in a wide class of inflationary scenarios. We develop a solution for the evolution of such nonlinear perturbations which is exact to first order in a gradient expansion. As a first application, we demonstrate that in single field models of inflation there can be no parametric amplification of super-Hubble mo...
