The impact of radial migration on disk galaxy star formation histories I. Biases in spatially resolved estimates
I. Minchev, K. Attard, B. Ratcliffe +9
Knowledge of the spatially resolved star formation history (SFH) of disk galaxies provides crucial insight into disk assembly, quenching, and chemical evolution. However, most reco…

Empirical derivation of the metallicity evolution with time and radius using TNG50 Milky Way/Andromeda analogues
B. Ratcliffe, S. Khoperskov, I. Minchev +3
Recent works have used a linear birth metallicity gradient to estimate the evolution of the [Fe/H] profile in the Galactic disk over time, and infer stellar birth radii (R$_\text{b…
