The Universe is filled with profound mysteries. Supermassive black holes have been observed to exist as early as 400 million years after the Big Bang. At the same time, dark matter, which comprises 85% of the mass in the Universe, remains largely mysterious. This proposal aims to address both of these fundamental questions through a unified theoretical framework. We propose that a self-interacting dark matter halo can collapse into a seed black hole in the early Universe, providing a potential explanation for the rapid formation of supermassive black holes.
We will conduct numerical simulations to investigate the formation and evolution of supermassive black holes during the cosmic dawn, comparing our theoretical predictions with observations from the James Webb Space Telescope. Furthermore, we will explore related signatures in the later Universe through observations of stellar streams, satellite galaxies, strong gravitational lenses. This work has the potential to significantly advance our understanding of both supermassive black hole formation and the nature of dark matter. Our findings will be disseminated through original research publications and presentations to the scientific community. We are also committed to fostering an inclusive environment for the junior researchers involved in this project.
