Abstract:
We study the properties of the nuclear molecular gas of the ultra
luminous merger Arp 220 and effects of the nuclear source on gas
excitation and chemistry. Specifically, our aim is to investigate the
spatial location of the luminous HNC 3-2 line emission and address the
underlying cause of its unusual brightness.
We present high resolution observations of HNC J=3-2 with the
submillimeter array (SMA).
