Systematically Peculiar Molecular Composition in M 82: Regarding the Formation Mechanisms
Published online by Cambridge University Press: 30 March 2016
Abstract
A systematically peculiar molecular composition has been found in a nearby starburst galaxy M 82. Molecules related to grain surface formation and to production reactions favorable at high-temperature are deficient in M 82 among nearby galaxies with rich gas. These molecules are SO, SiO, NH3, HNCO, CH3OH, and CH3CN. Possible reasons for this peculiarity are discussed.
