AGN and Galaxies Through the Ages

The AGN and Galaxies Through the Ages (AGATHA) Group at Universidad Diego Portales conducts research that focuses on the evolution of galaxies and active galactic nuclei (AGN) over cosmic time, out to the earliest systems. For this we use a variety of astronomical facilities, techniques and tools.
