Obscured quasars are a type of active galactic nuclei (AGN) that are hidden or obscured by dust and gas from our line of sight. These quasars emit large amounts of energy and are powered by supermassive black holes at the center of galaxies. The obscuring material can make it difficult to study these quasars directly, but they can be detected through other observational methods such as infrared or X-ray observations. Research in this area focuses on understanding the properties and behavior of obscured quasars, as well as their role in galaxy evolution and the overall structure of the universe.
