Unveiling the Hubble constant through galaxy cluster gas mass fractions

Physics Letters B
In this work, we obtain Hubble constant (H0) estimates by using two galaxy cluster gas mass fraction measurement samples, Type Ia supernovae luminosity distances, and the validity of the cosmic distance duality relation.

Status Report on the Chicago-Carnegie Hubble Program (CCHP): Measurement of the Hubble Constant Using the Hubble and James Webb Space Telescopes

The Astrophysical Journal
We present the latest results from the Chicago-Carnegie Hubble Program to measure the Hubble constant, using data from the James Webb Space Telescope (JWST). The overall program aims to calibrate three independent methods: (1) tip of the red giant branch

Testing the coupling of dark radiations in light of the Hubble tension

European Physical Journal C: Particles and Fields
We are studying the effects of Self-Interacting dark radiation (SIdr) on the evolution of the universe. Our main focus is on the cosmic microwave background (CMB) and how SIdr could potentially help resolve the Hubble tension.

Determination of the Hubble Constant

, 1996
Recent developments in the determination of H0 are reviewed in the context of the 3 following questions: 1) What is required to measure an accurate value of H0? Given the wide range of H0 values quoted in the current literature, is there any evidence that the situation has changed very much at all in the last couple of decades? And 3), is a measurement

Model-independent Way to Determine the Hubble Constant and the Curvature from the Phase Shift of Gravitational Waves with DECIGO

The Astrophysical Journal Letters
In this Letter, we propose a model-independent method to determine the Hubble constant and curvature simultaneously by taking advantage of the possibilities of future spaceborne gravitational-wave detector DECIGO in combination with the radio quasars as ...

Newest Measurements of Hubble Constant from DESI 2024 Baryon Acoustic Oscillation Observations

The Astrophysical Journal Letters
In this Letter, we use the latest results from the Dark Energy Spectroscopic Instrument (DESI) survey to measure the Hubble constant. Baryon acoustic oscillation (BAO) observations released by the DESI survey, allow us to determine H _0 from the first ...

Tension in the Hubble constant

, 2017
There has been some hand-wringing of late about the tension between the value of the expansion rate of the universe – the famous Hubble constant, H ₀ , measured directly from observed redshifts and distances, and that obtained by multi-parameter fits to the cosmic microwave background.
