摘要
我们描述了利用 Anglo-Australian 望远镜上的 Taurus 可调滤波器对星盘进行吸收线成像的技术，并展示了其对与 Mg 和 Fe 相关的光谱特征灵敏度。 presented for a sample of eight face-on spiral galaxies spanning a range of Hubble types. We report signatures of phenomena including merger-induced star formation, HII rings and galactic bars. This study demonstrates the capacity of tunable filters to measure Mg and Fe line-strengths across the face of spiral galaxies, which can ultimately reveal clues about the star formation history and chemical evolution.
