Hector - a revolutionary spectrograph for understanding how galaxies evolve: The project team recently demonstrated the extraordinary power of a new Sydney-Australian Astronomical Observatory Multi-object Integral-field spectrograph (SAMI) at the Anglo-Australian Telescope. This early prototype demonstrated it was possible to place 13 hexabundles accurately onto the images of 13 galaxies and to obtain spectroscopy at 61 contiguous positions across each galaxy. This provides a wealth of information about stars and gas in each galaxy. SAMI has generated enormous interest in new science across the Australian and international community. This project intends to develop a far more powerful facility, 'Hector', that will allow us to answer new scientific questions. For the first time, we will learn how the properties of galaxies evolve with their surrounds, and what this tells us about how galaxies form.

赫克托-一个革命性的光谱仪，用于理解星系是如何演变的：项目团队最近在英澳望远镜上展示了一个新的悉尼-澳大利亚天文台多目标积分场光谱仪（SAMI）的非凡力量。这个早期的原型表明，将13个六倍体精确地放置在13个星系的图像上，并在每个星系的61个连续位置获得光谱是可能的。这为每个星系中的恒星和气体提供了丰富的信息。SAMI引起了澳大利亚和国际社会对新科学的极大兴趣。这个项目打算开发一个更强大的设备，“赫克托耳”，这将使我们能够回答新的科学问题。这是第一次，我们将了解星系的性质是如何随着它们的周围环境而演变的，以及这告诉我们星系是如何形成的。
