本文介绍了星暴星系M82的新的近红外观测，包括高分辨率J、H和K图像，1-5 μm分光光度计和光度计，以及1.05-1.35 μm光谱学。这些测量被用来检查星系中的恒星数量和星际介质中的条件。我们联合收割机结合我们的观察结果从文献中推导出一组新的约束星爆模型，这是在一个配套文件。我们的帕邢线通量的测量结合其他重组线的强度允许研究的红化在M82。我们发现，一个统一的前景屏幕模型的尘埃几何形状不能解释的相对线强度
We present new near-infrared observations of the starburst galaxy M82, including high-resolution J, H, and K imagery, 1-5 μm spectrophotometry and photometry, and 1.05-1.35 μm spectroscopy. These measurements are used to examine the stellar population in the galaxy and conditions in the interstellar medium. We combine our observations with results from the literature to derive a new set of constraints for starburst models, which are presented in a companion paper. Our measurements of Paschen line fluxes in combination with the strengths of other recombination lines allow study of the reddening in M82. We find that a uniform foreground screen model for the dust geometry cannot explain the relative line strengths
