Spatially resolved SFH of isolated spiral galaxies

New integral field spectroscopy data for nearby galaxies provide us with data at sufficient resolution to study the Star Formation History (SFH) over the disk of a galaxy. Using MaNGA data, my research at University of Antofagasta aims to understand how exactly do galaxies build their disk when they grow in isolation, unaffected by external influences. To do so, we constraint the physical parameters of the stellar populations along the disk by comparing with modeled spectra. From models, it is predicted that the disk grows inside out, but here we show that the SFH of spiral galaxies is more complex than previously thought.
