Living Reviews in Relativity, 2015 I review the current state of determinations of the Hubble constant, which gives the length scale of the Universe by relating the expansion velocity of objects to their distance. There are two broad categories of measurements.

Measuring the Hubble constant with a sample of kilonovae [PDF]
Nature Communications, 2020 Kilonovae observations can be used to out constraints on the Hubble constant (H0). Here, the authors show H0 measurements by combining light curves of four short gamma-ray burts with GW170817 are about a factor of 2-3 more precise than the standard-siren

Maximum Entropy Estimates of Hubble Constant from Planck Measurements [PDF]
EntropyA maximum entropy (ME) methodology was used to infer the Hubble constant from the temperature anisotropies in cosmic microwave background (CMB) measurements, as measured by the Planck satellite.

Why reducing the cosmic sound horizon alone can not fully resolve the Hubble tension
Communications Physics, 2021 It is generally accepted that the Universe is dominated by dark energy but the different methods to measure the Hubble constant disagree, giving origin to what is known as the "Hubble tension”. The authors demonstrate that the sole reduction of the sound

Physics Letters B, 2023 Hubble constant is found relating velocities and distances of galaxies. Actually Cepheid stars and cosmic background radiation present two distinct values for the Hubble constant.

The Astrophysical Journal Letters, 2023 High-resolution James Webb Space Telescope (JWST) observations can test confusion-limited Hubble Space Telescope (HST) observations for a photometric bias that could affect extragalactic Cepheids and the determination of the Hubble constant.

Hubble constant in the axi-Higgs universe
Physical Review Research, 2023 The Λ-cold-dark-matter (ΛCDM) model provides an excellent fit to the cosmic microwave background (CMB) data. However, a statistically significant tension emerges when its determination of the Hubble constant H_{0} is compared to the local distance ...

Anthropic Principle and the Hubble-Lemaître Constant
Galaxies, 2022 According to the weak formulation of the anthropic principle, all fundamental physical constants have just such values that they enabled the origin of life.

Supernova calibration by gravitational waves
European Physical Journal C: Particles and Fields, 2023 Hubble tension is one of the most important problems in cosmology. Although the local measurements on the Hubble constant with Type Ia supernovae (SNe Ia) are independent of cosmological models, they suffer the problem of zero-point calibration of the ...
