We propose a programme of Astrophysics, Cosmology and Technology development for Astrophysics and Cosmology, to investigate star and planet formation in our own and other galaxies, how galaxies form and evolve and the signals from the very early Universe embedded in the polarisation properties of the Cosmic Microwave background. This programme will combine observational data from world-class ground and space-based observatories, as well as theoretical modelling and simulations of the processes that result in the Universe we observe around us. We will also continue to develop the world's most sensitive detectors for very long infrared wavelengths, along with associated optical components utilising 'metamaterials' the class of materials designed and manufactured by human beings to have the properties best suited to their task, rather than relying on naturally occurring minerals and plastics. Both of these areas of technology development potentially have wide applications outside of Astronomy, in areas such as security scanners and bio-medical imaging for example.

我们提出了一个天体物理学，宇宙学和技术发展的天体物理学和宇宙学，研究星星和行星的形成，在我们自己和其他星系，星系如何形成和演变的信号，从非常早期的宇宙嵌入在宇宙微波背景的偏振特性。该方案将结合来自世界级地面和空间观测站的联合收割机观测数据，以及对形成我们周围观测到的宇宙的过程进行理论建模和模拟。我们还将继续开发世界上最灵敏的长红外波长探测器，沿着相关的光学元件，这些元件利用“超材料”，即人类设计和制造的具有最适合其任务的特性的材料，而不是依赖于天然存在的矿物和塑料。这两个技术发展领域在天文学之外都有广泛的应用，例如安全扫描仪和生物医学成像。
