A NEW METHOD FOR MEASURING METALLICITIES OF YOUNG SUPER STAR CLUSTERS

We demonstrate how the metallicities of young super star clusters (SSC) can be measured using novel spectroscopic techniques in the J-band. The near-infrared flux of SSCs older than ~6 Myr is dominated by tens to hundreds of red supergiant stars. Our technique is designed to harness the integrated l...
