Hector - a revolutionary spectrograph for understanding how galaxies evolve

Hector--了解星系演化的革命性光谱仪：该项目团队最近在英澳望远镜上展示了一台新的悉尼-澳大利亚天文台多目标积分场光谱仪(SAMI)的非凡威力。这个早期的原型证明了将13个六丰度元素准确地放置在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。这提供了关于每个星系中恒星和气体的丰富信息。SAMI在澳大利亚和国际社会引起了对新科学的巨大兴趣。这个项目打算开发一个功能更强大的设备--赫克托，它将允许我们回答新的科学问题。我们将第一次了解星系的性质如何随其周围环境的变化而演变，以及这告诉我们关于星系是如何形成的。

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.
