The evolution of galaxies in terms of mass accretion and matter transport is still an open topic in research. My thesis consists of two parts that are bridged by a common theme: the properties of the interstellar medium interstellar matter (ISM) and star formation in centers of galaxies, studied in the (sub-)mm wavelength regime. The first part of my thesis deals with the results from Submillimeter Array (SMA) ob- servations of molecular gas (low CO transitions) at sub-kpc (∼3′′) resolution of three Seyfert 1 galaxies from the ’low-luminosity quasi stellar object (LLQSO) sample’, which covers a redshift range of z ∼ 0.01 - 0.06. The goal of the LLQSO sample is investigate the signs of internal or external triggers enhanced activity (i.e., ...
