Unraveling the Enigma of Dark Matter: Axions and the Standard Cosmological Model
An international team of astrophysicists and cosmologists have submitted five papers suggesting that the "clumpiness" of dark matter in the universe, known as the S8 value, is 0.76, conflicting with the value of 0.83 derived from the Cosmic Microwave Background. This discrepancy could indicate measurement errors or an incomplete standard cosmological model. The team used advanced techniques and the Hyper Suprime-Cam to study dark matter's clumpiness, analyzing data from the first three years of the survey. The results, uploaded as pre-print papers to arXiv, highlight the need for further investigation into the nature of dark matter and the accuracy of current cosmological models.
