Recent research has proposed a solution to the mystery of how super-massive black holes formed so quickly in the early universe. A new physics model suggests that ultra-self-interacting dark matter plays a crucial role in the formation of these black holes, which appear to have masses exceeding a billion times that of the sun just 800 million years post-Big Bang. Traditionally, cosmological models have struggled to explain this rapid growth, as they generally assume dark matter interacts only through gravity.
The researchers introduced the concept of ultra-self-interacting dark matter, a subcomponent that comprises less than 10% of the dark matter in the early universe, exhibiting strong self-interactions. This self-interaction helps dark matter particles cluster in galactic centers, facilitating their collapse into super-massive black holes. This process enables black holes to form and grow much faster than traditional models allow.
The study involved analyzing quasar data from the James Webb Space Telescope (JWST) to validate the model’s accuracy against observed black hole parameters, showing that it could reproduce observed masses and ages satisfactorily. The model’s predictions extend to the existence of central mass black holes in dwarf galaxies, which can be tested by future observations.
Published in the Journal of Cosmology and Astroparticle Physics, the findings emphasize the need for further observations from JWST to refine models of ultra-self-interacting dark matter and enhance understanding of how these ancient black holes formed.
