Venturing into the Cluster Desert

关于宇宙的性质和命运的基本问题不仅引起天文学家的兴趣，而且引起普通公众的兴趣。特别是，宇宙由暗能量主导的认识引发了广泛的公众兴趣。我们对暗能量所知甚少。它是爱因斯坦著名的宇宙常数，还是更奇特的东西，比如一种新粒子，甚至是一种新的物理学？这个提议的目的是建立一个非常遥远的星系团样本，然后可以用来寻找一种非常特殊的超新星——Ia型超新星，它可以用作了解暗能量特性的工具。

Fundamental questions that ask about the nature and the fate of the Universe are of interest not only to astronomers, but also to the general public. In particular, the realisation that the Universe is dominated by dark energy has sparked wide public interest. We still know very little about dark energy. Is it Einstein's famous cosmological constant or something more exotic, such as a new particle or even new physics? This proposal aims to build a sample of very distant galaxy clusters that can then be used to search for a very special type of supernova - the Type Ia Supernova, which can be used as a tool to learn about the properties of dark energy.
