How did supermassive black holes grow so quickly in the early Universe? Our latest research suggests that soliton cores in fuzzy dark matter (FDM) may hold the key to this cosmic mystery. Using high-resolution FDM cosmological simulations, we find that massive solitons naturally form in the early Universe, creating deep gravitational wells that accelerate gas accretion and boost black hole growth by 2–4 orders of magnitude.

超大質量黑洞為何能在宇宙早期迅速成長？我們的研究指出，波暗物質中的孤粒子可能是關鍵。超高解析度的宇宙學電腦模擬揭示，早期宇宙中自然形成的孤粒子，能加深重力位井，顯著加速氣體吸積，將黑洞成長速率提升二至四個數量級，有望解開早期類星體之謎。
