How do black holes wreak havoc on galaxies? A growing black hole is the most efficient source of power in the Universe, unlocking rest-mass energy bound in gas and stars it consumes by accretion and unleashing bursts of energetic radiation. The goal of the research programme is to understand how these outbursts impact on a black hole's environment and to quantify the impact of black holes on how galaxies form. Using cutting edge supercomputer models, this project will study how outbursts of feedback from black holes, ranging from one to one billion times the mass of the Sun, impact on star formation and gas content in galaxies. The results of the research will provide crucial insights into accretion power as a source of feedback in galaxy formation.

黑洞是如何对星系造成破坏的？一个不断成长的黑洞是宇宙中最有效的能量来源，它通过吸积和释放高能辐射的爆发释放出束缚在气体和恒星中的静止质量能量。研究计划的目标是了解这些爆发如何影响黑洞的环境，并量化黑洞对星系形成的影响。该项目将利用最先进的超级计算机模型，研究质量为太阳1至10亿倍的黑洞反馈的爆发如何影响星系中星星的形成和气体含量。研究结果将为吸积功率作为星系形成反馈源提供重要见解。
