Abstract: In order to understand the evolution and formation of galaxies, it is crucial to obtain sensitive observations of the emission of dust and molecular gas. Both constrain the on-going star formation or AGN activity and the future potential of the galaxy to grow. Understanding the growth of the ensemble of galaxies in the distant universe, is one of the primary goals of current and planned (sub)mm facilities. To shed light on this topic, I will present our on-going observations of dust and molecular gas at different environments with a number of (sub)mm facilities such as ATCA, Herschel, APEX, IRAM and/or ALMA of one important star forming galaxy population in the distant universe: submillimeter selected galaxies (SMGs). I will focus on the built-up of the progenitors of galaxy clusters seen in the local universe, the so-called galaxy protoclusters. Our work enables us to verify if dusty galaxies vigorously form stars around large scale structures. Finally, I will discuss the prospects of observations of newly started and planned telescope facilities and surveys on the presented topic.
