The cosmological ultra-low frequency radio background: a solution to the Hubble tension and the 21-cm excess trough
Abstract Recent observations of the Cosmic Microwave Background and the Hubble Space Telescope obtain two different values of the Hubble constant with a discrepancy of at least $$4.4 \sigma $$ 4.4 σ , which is now known as the Hubble tension. On the other hand, observations of 21-cm signal from the...
