The impact of radial migration on disk galaxy star formation histories: II. Role of bar strength, disk thickness, and merger history
J. P. Bernaldez, I. Minchev, B. Ratcliffe +7
Reconstructing the star formation history (SFH) of disk galaxies is central to understanding their growth and evolution, yet such estimates can be strongly biased by stellar radial…

Evolution of the radial ISM metallicity gradient in the Milky Way disk since redshift
Bridget Ratcliffe, Sergey Khoperskov, Ivan Minchev +5
Recent works identified a way to recover the time evolution of a galaxy's disk metallicity gradient from the shape of its age--metallicity relation. However, the success of the met…
