An 8\% Determination of the Hubble Constant from localized Fast Radio Bursts

Understand

The $\Lambda$CDM model successfully explains the majority of cosmological observations.

• However, the $\Lambda$CDM model is challenged by Hubble tension, a remarkable difference of Hubble constant $H_0$ between measurements from local probe and the prediction from Planck cosmic microwave background observations under $ \Lambda$CDM model.
• So one urgently needs new distance indicators to test the Hubble tension.
• Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances, which are attractive cosmological probes.
