Abstract:
We have used previously published observations of the CO emission from
the Antennae (NGC 4038/4039) to study the detailed properties of the
supergiant molecular complexes with the goal of understanding the
formation of young massive star clusters.
Description:
The CO observations of the Antennae originally presented in Paper I
(Wilson et al., 2000ApJ...542..120W 2000ApJ...542..120W) were obtained with the Caltech
Millimeter Array between 1998 March and 1999 February.
