Description
The standard method of mapping the interstellar medium in a galaxy, by
observing the molecular gas in the CO 1-0 line and the atomic gas in the
21-cm line, is largely limited with current telescopes to galaxies in
the nearby universe. In this letter, we use SPIRE observations of the
galaxies M 99 and M 100 to explore the alternative approach of mapping
the interstellar medium using the continuum emission from the dust. We
have compared the methods by measuring the relationship between the
star-formation rate and the surface density of gas in the galaxies using
both methods. We find the two methods give relationships with a similar
dispersion, confirming that observing the continuum emission from the
dust is a promising method of mapping the interstellar medium in
galaxies.
