This project plans to measure how supermassive black holes have evolved over the last 12 billion years. Direct measurements of central black hole masses only exist for about 40 relatively nearby galaxies. The unique time-lapse observations and five-year baseline of the Australian Dark Energy Survey will enable us to measure masses for about 400 black holes, an order of magnitude more than previously possible. In addition to weighing black holes, recent results show that with precision measurement these systems may provide a standard candle, a new fundamental yardstick for cosmology. Unlike supernova observations that discovered dark energy, our measurements are practical to distances stretching back across 90 per cent of the observable universe.

该项目计划测量超大质量黑洞在过去120亿年中是如何演化的。对中心黑洞质量的直接测量只存在于大约40个相对较近的星系中。澳大利亚暗能量调查独特的延时观测和五年基线将使我们能够测量大约400个黑洞的质量，比以前可能的数量级多。除了测量黑洞的重量，最近的结果表明，通过精确测量，这些系统可能会提供一个标准蜡烛，一个新的宇宙学基本尺度。与发现暗能量的超新星观测不同，我们的测量实际上可以追溯到可观测宇宙的90%。
