Abstract:
Much of the growth of galaxies' central stellar mass and their black holes may occur during phases where galaxy centers are heavily obscured. New and recent facilities such as the James Webb Space Telescope, the Atacama Large Millimeter Array, and NuSTAR can be used to probe these obscured and energetic environments. I will discuss recent findings about the obscuration towards active galactic nuclei in mergers and show progress in understanding the nature and power source of the enigmatic "Compact Obscured Nuclei". I will conclude with a look towards multi-messenger exploration of galaxy nuclei, by showing a new model for TeV neutrino emission from starbursts and IceCube flux predictions for low-redshift infrared galaxies.
