The Galactic Centre Mini-Spiral with CARMA
Abstract
The Galactic centre mini-spiral region is a mixture of gas and dust with temperatures ranging from a few hundred K to 10(exp 4) K. We report results from 1.3 and 3mm radio interferometric observations of this region with CARMA, and present a spectral index map of this region. We find a range of emission mechanisms in the region, including the inverted synchrotron spectrum of Sgr A*, free-free emission from the mini-spiral arms, and a possible dust emission contribution indicated by a positive spectral index.
