| Description |
We propose to use the SPIRE and PACS instruments on Herschel to measure theemission spectrum from dust as well as important cooling lines from the gaseous interstellar medium in sample of 13 very nearby galaxies (M51, M81, NGC2403, NGC891, M83, M82, Arp220, NGC4038/39, NGC1068, NGC4151, CenA, NGC4125, and NGC205). These galaxies have been chosen to probe as wide a regionin galaxy parameter space as possible while maximizing the achievable spatialresolution and are already well-studied from X-ray and optical throughto radio wavelengths. The far-infrared and submillimeter wavelengths probed byHerschel are absolutely crucial for understanding the physical processesand properties of the interstellar medium,the interplay between star formation and the interstellar medium in galaxies, and how they may depend on the wider galaxian environment. |
