There is an extensive zoo of different galaxies where supermassive blackholes are growing in the centre, and around which stars are forming very vigorously. These processes are coupled to the surrounding galaxy, and both respond to, and are perhaps responsible for shaping, their evolution and environment. A large number of exciting objects of this sort have been discovered by the WISE infrared space survey, including many of the most luminous galaxies of all time.From a range of observations all the way from X-ray to radio wavelengths, and by comparing with information from relatively easy-to-study nearby galaxies, we will test the ideas about how these most remarkably luminous objects are generated, and the processes within that control their properties and tremendously high rate of energy release, that cannot be sustained indefinitely. We anticipate focussing on the properties and processes in their interstellar media, and understanding their nature using images and spectra from the Atacama Large (Sub)millimetre Array (ALMA), the James Webb Space Telescope (JWST), and large ground-based telescopes.

有一个大范围的不同星系动物园，中心正在生长着超大质量黑洞，周围的恒星正在非常活跃地形成。这些过程与周围的星系相耦合，两者都对它们的演化和环境做出反应，或许也对它们的形成负责。WISE红外太空勘测发现了大量这类令人兴奋的天体，其中包括许多有史以来最明亮的星系。从X射线到射电波长的一系列观测，并通过与附近相对容易研究的星系的信息进行比较，我们将测试这些最明亮的天体是如何产生的，以及其中控制它们的性质和极高的能量释放率的过程，这是不可能无限持续的。我们预计将利用阿塔卡马大(亚)毫米阵列(ALMA)、詹姆斯·韦伯太空望远镜(JWST)和大型地面望远镜的图像和光谱，重点研究它们的星际介质的性质和过程，并了解它们的本质。
