标题： Observation of Extended Red Emission (ERE) in the halo of M82

摘要： 沿着M82星系的轴线和尘埃晕，从4000年到9600年获得了低色散光谱。 该晕的光谱可以用尘埃颗粒对银河系光的散射来解释：当它们除以星系光谱时，会显示出一个宽发射带，类似于（但比）在星系反射星云中常见的扩展红光发射（ERE）凸起。 这一特征在晕的丝状部分尤为明显。 这是首次在银河系外探测到ERE。 显示英文摘要

摘要： Low-dispersion spectra have been obtained from 4000 to 9600 \AA~along the axis and across the dusty halo of the galaxy M82. The spectra of the halo are explained in terms of scattering of the galactic light by dust grains: when divided by the spectrum of the galaxy, they reveal a broad emission band, similar to, although wider than the bump of Extended Red Emission (ERE) commonly observed in galactic reflection nebulae. The feature is particularly well marked in the filamentary parts of the halo. This is the first detection of ERE outside of our Galaxy.
