dc.description.abstractWe present wide field-of-view near-infrared imaging from the NTT and very deep optical imaging from the HST of the young merging galaxy NGC 3597. The morphology of the galaxy and the properties of the newly formed protoglobular clusters (PGCs) are examined. Our K-band data reveal the presence of a second nucleus, which provides further evidence that NGC 3597 is the result of a recent merger. Combining new K-band photometry with optical photometry, we are able for the first time to derive a unique age for the newly formed PGCs of a few Myr. This is consistent with the galaxy starburst age of less than or equal to 10 Myr. From deep HST imaging, we are able to probe the luminosity function similar to 8 magnitudes fainter than normal, old globular clusters, and confirm that the PGCs have a power-law distribution with a slope of similar to-2.
