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]
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]
A 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.

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

Hubble constant in the axi-Higgs universe
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 ...

Supernova calibration by gravitational waves
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 ...

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

CATS: The Hubble Constant from Standardized TRGB and Type Ia Supernova Measurements
The tip of the red giant branch (TRGB) provides a luminous standard candle for constructing distance ladders to measure the Hubble constant. In practice, its measurements via edge-detection response (EDR) are complicated by the apparent fuzziness of the ...
