摘要：

We present Preliminary results from a set of near-IR integral field spectroscopic observations of the central, star-burst, regions of the barred spiral galaxy M83, obtained with CIR-PASS on Gemini-S. We present maps in the Pabeta and [FeII] 1.257 mum emission lines which appear surprisingly different. We outline the procedure in which we will use Pabetaemission line strengths and measures of CO absorption to determine the relative and absolute ages of individual star-forming knots in the central kpc region of M83.
