Molecular Chemistry as Diagnostic tool for Starbursts and AGNs
The Molecular ISM of NGC 4418
Onsala Rymdobservatorium, Chalmers Tekniska Högskola, 439 92
We present a brief discussion of the statistical surveys of HCN, HNC, HCO+ and HC3N that are used to model the extreme environments in the nuclei of starbursts and AGNs. Molecular studies are particularly useful for probing the deeply enshrouded dusty nuclei of luminous infrared galaxies. Here we present NGC 4418 as an example, one of the closest LIRG with high obscuration of the inner region. The interpretation of the observed line ratios require parallel development of theoretical chemical and radiative transport models.
