Star Clusters in Mergers
... What can we say about the Stellar Component in the Antennae ? In our 1999 paper, one of our primary difficulties was differentiating stars from clusters. This led us to conclude that the number of young star clusters in the Antennae was between 800 and 8000, a pretty big range ! Our new ACS data pr ...
