This project aims to increase our understanding of the workings of the central regions of galaxies. The nuclei of galaxies are galactic-scale powerhouses driven by fast-moving winds launched by either the active bursts of star formation in the galaxy’s core or the accretion of gas onto a central black hole more than a million times the mass of the Sun. In 2010, the Fermi space telescope discovered enormous bubbles filled with hot gas emanating from the centre of the Milky Way, proof of a Galactic wind. Our Galaxy's wind offers the best laboratory in the universe for understanding what drives the powerhouses at the nuclei of normal galaxies. This project aims to determine whether the Milky Way’s nuclear wind and the Fermi bubbles were formed from a starburst wind or gas accretion onto the central black hole.

这个项目旨在增加我们对星系中心区域的工作原理的了解。星系核是星系规模的动力源，由快速移动的风驱动，风是由银河系核心恒星形成的活跃爆发或气体吸积到质量超过太阳一百万倍的中央黑洞而发起的。2010年，费米太空望远镜发现了从银河系中心散发出来的充满热气的巨大气泡，这证明了银河系的风。我们银河系的风提供了宇宙中最好的实验室，以了解是什么驱动了正常星系核心的发电站。该项目旨在确定银河系的核风和费米气泡是否是由星暴风或气体吸积到中央黑洞形成的。
