Can Inflation Resolve the Hubble Tension?

Universe
In this work, we investigate how a change in the sound horizon due to inflation may affect the value of H0. Performing an analysis using the measurements of BAO, SN Ia, H(z), CMB, and the local H0, we show that the modification in the sound horizon ...

New H(z) Measurement at Redshift = 0.12 with DESI Data Release 1

The Astrophysical Journal
The Hubble parameter ( H ( z )) is a function of the redshift and a reliable measurement is very important to understand the expansion history of the Universe.

Blinded Mock Data Challenge for Gravitational-wave Cosmology. I. Assessing the Robustness of Methods Using Binary Black Hole Mass Spectrum

The Astrophysical Journal
Gravitational wave sources are standard sirens that provide an independent way to map the cosmic expansion history by combining with an independent redshift measurement, either from an electromagnetic counterpart for a bright siren or using different ...

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

Golden and Silver Dark Sirens for Precise H0 Measurement with HETDEX

The Astrophysical Journal
Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source’s luminosity distance, enabling an independent measurement of the Hubble constant ( H _0 ).

The pursuit of the Hubble Constant using Type II Supernovae [PDF]

, 2023
The use of multiple independent methods with their own systematic uncertainties is crucial for resolving the ongoing tension between local and distant measurements of the Hubble constant ($H_{0}$). While type Ia supernovae (SNe Ia) have historically been

Hubble Constant and Strong Gravitational Lensing [PDF]

The persistent tension between early and late universe measurements of the Hubble constant (H0) represents one of the most significant challenges in modern cosmology, with implications for our understanding of fundamental physics.
