Exploring the Hubble Tension Problem with Phantom Dark Energy

Recently, the observed equation of state for dark energy appears to favor values below −1. The tendency implies that the nature of dark energy may be quite different from that of the cosmological constant. In view of this, the introduction of the phantom energy seems inevitable. By employing observational constraints from supernovae and from the acoustic scale in which the accuracy of the data has become extraordinary, the research team applied a phenomenological scenario to be acquainted with the evolution of our universe. The demonstration of the constrained unfolding of the phantom energy shows that the model has high consistency with the current observation, suggesting that if it is phantom dark energy that is causing the accelerating expansion of the universe instead of the cosmological constant, then the Hubble constant may be different from the recent observations, and the “Hubble tension” problem may not be as severe as expected.
