We present an analysis of the properties of the hot interstellar medium ( ISM ) in the merging pair of galaxies known as The Antennae ( NGC 4038/39 ) , performed using the deep , coadded \sim 411 ks Chandra ACIS-S data set .
These deep X-ray observations and Chandra ’ s high angular resolution allow us to investigate the properties of the hot ISM with unprecedented spatial and spectral resolution .
Through a spatially resolved spectral analysis , we find a variety of temperatures ( from 0.2 to 0.7 keV ) and N _ { H } ( from Galactic to 2 \times 10 ^ { 21 } cm ^ { -2 } ) .
Metal abundances for Ne , Mg , Si , and Fe vary dramatically throughout the ISM from sub-solar values ( \sim 0.2 ) up to several times solar .
