A crucial yet unexpected piece of the puzzle of the general framework of galaxy evolution is the existence of supermassive black holes (SMBHs) and how they are linked to their host galaxies. Despite the vast difference in physical sizes between SMBHs and galaxies, the energy released through accretion onto these SMBHs (manifested as ``active galactic nuclei’’, or AGNs) plays an important role in regulating the growth of galaxies, therefore shaping the well-established, tight relation between SMBH mass and galaxy bulge properties. I will discuss results of recent multiwavelength observational studies on several aspects of the SMBH-galaxy coevolution paradigm, with a focus on how we can use the latest deep-wide X-ray surveys to catch the accreting SMBHs that might be ``hidden'' in plain sight.
