Star Forming Molecular Gas in Early Stage Mergers
While the simulations have predicted a number of intriguing aspects of the gas response during the early stages of a galaxy collision, only a handful of observational tests exist in literature so far. We performed observation of early stages galaxies with Nobeyama45m CO(1-0) and ASTE10m CO(3-2). An extensive survey of molecular gas along the complete merger sequence will finally allow us a detailed comparison with the predictions from numerical simulations.
