The H0 trouble: Confronting Non-thermal Dark Matter and Phantom Cosmology with the CMB, BAO, and Type Ia Supernovae data

Understand

We have witnessed different values of the Hubble constant being found in the literature in the past years.

• Albeit, early measurements often result in an $H_0$ much smaller than those from late-time ones, producing a statistically significant discrepancy, and giving rise to the so-called Hubble tension.
• The trouble with the Hubble constant is often treated as a cosmological problem.
• However, the Hubble constant can be a laboratory to probe cosmology and particle physics models.
