Chemical Composition in a Merging Galaxy NGC3256 ~ALMA new results~
NGC3256 is late stage merging galaxy and SB/AGN activity is considered to strongly impact the chemical and physical properties of ISM. Chemical properties as traced in molecular gas composition contain significant information that will tell us the current state and duration of the SB/AGN activities, and how that is affected by the ongoing tidal interaction. The spectrum of our previous LMT line survey seems to be like SB galaxies not AGN-host galaxies, however it reflects mean value of double nuclei. High resolution and sensitivity imaging of numerous molecules with ALMA is strong tool to create accurate picture of NGC3256. We introduce the newest results of ALMA cycle3 observation.
