The Hubble constant tension: current status and future perspectives through new cosmological probes

M Dainotti, B De Simone, G Montani… - arXiv preprint arXiv …, 2023 - arxiv.org
The Hubble constant ($ H_0 $) tension is one of the major open problems in modern
cosmology. This tension is the discrepancy, ranging from 4 to 6$\sigma $, between the …

Cosmic chronometers to calibrate the ladders and measure the curvature of the Universe. A model-independent study

A Favale, A Gómez-Valent… - Monthly Notices of the …, 2023 - academic.oup.com
We use the state-of-the-art data on cosmic chronometers (CCH) and the Pantheon+

Quantifying effects of inhomogeneities and curvature on gravitational wave standard siren measurements of

SM Koksbang - Physical Review D, 2022 - APS
For a flat Λ CDM universe, the dipole of the luminosity distance can be utilized to measure
the Hubble parameter. It is here shown that this is not the case in more general settings …
