This book explores the critical need for a comprehensive census of supermassive black holes in the local universe, particularly within low mass galaxies. Supermassive black holes play a crucial role in the co-evolution of active galactic nuclei (AGN) and their host galaxies. To uncover these elusive entities, infrared selection criteria, such as the [3.4]-[4.6] m (W1-W2) color, offer a valuable method for detecting obscured AGN that might remain hidden in X-ray or optical surveys. Recent research has revealed a surprising abundance of AGN in low mass galaxies, challenging traditional optical selection criteria. Furthermore, it suggests a substantial population of obscured AGN, particularly in low mass galaxies. However, the nature of the dust heating that leads to high W1-W2 color remains a question

In this thesis I use far-infrared (far-IR) observations performed by the Herschel Space Observatory to study dusty star-forming galaxies, which are believed to be the likely progenitors of massive elliptical galaxies. More specifically, I investigate the far-IR emission of dust-obscured galaxies (DOGs), analyze the near-IR imaging of Herschel-selected lensed galaxies, and investigate the rest-frame UV emission of HFLS3, a z=6.34 Herschel-selected starburst.
