Scientific paper

We present Gemini-South observations of the nuclear starburst region of M83, using the CIRPASS near-IR integral-field spectrograph. Spectroscopic diagnostics are used to overcome many of the uncertainties inherent to photometric studies of the star-formation history of the central region of M83. We use Paβ and [Fe II] emission, and absorption in the CO(6,3) band head, to infer an age gradient, as opposed to stochastic star formation, across the nuclear star-forming region of M83.
