Abstract: Supermassive black holes are the engines that drive the evolution of the most massive galaxies in the Universe. A tight feedback loop that is yet to be understood in detail ensures a delicate balance between the heating driven by SMBH jets and radiative cooling, thus quenching star formation. I will discuss the role of low-temperature molecular and atomic gas clouds, traced by their CO, [CII], and Halpha nebular line emission, in this feedback loop, focusing on how their mass and kinematics are affected by the SMBH.
