Stellar Age Compression Reshapes Interpretations of the Milky Way Thick-Disk Formation History

ArXi:2605.10220v1 Announce Type: cross The formation timescale of the Milky Way thick disk is one of the central debates in Galactic archaeology. The age-metallicity relation (AMR), formation timescale, and chemical evolution gradients are frequently used to infer a rapid assembly, short-timescale enrichment, and bursty formation history of the thick disk.
