我们报告在M82的银面上下探测到一个面外温暖的H2结和丝的复合体，延伸超过3 kpc，大致与该系统中众所周知的星系风一致。将这些数据与其他波长的已发表结果进行比较，可以提供拓扑结构、激发、加热以及在这种典型星系风中被风携带的星际分子物质的稳定性方面的定量约束。像这样的深H2 2.12 μm观测代表了一种有希望的新方法来研究难以捉摸但潜在重要的星系风分子成分。
We report the detection of a complex of extraplanar warm H2 knots and filaments extending more than ∼3 kpc above and below the galactic plane of M82, roughly coincident with the well-known galactic wind in this system. Comparisons of these data with published results at other wavelengths provide quantitative constraints on the topology, excitation, heating, and stability against disruption of the wind-entrained molecular interstellar matter in this prototypical galactic wind. Deep H2 2.12 μm observations such as these represent a promising new method to study the elusive but potentially important molecular component of galactic winds.
