Popis: | 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 |
