DESCRIPTION:Modern astronomy has entered a regime in which the central chal
 lenge is no longer data acquisition\, but data integration. Billions of sta
 rs are now observed across (phase-)space\, frequency\, and time\, yet each 
 modality captures only a partial view of the processes that shape our Galax
 y. The next frontier in Galactic archaeology lies in unifying these dimensi
 ons into a coherent framework.\n\nIn this talk\, I will present new data-sc
 ience methods that integrate spectroscopy\, asteroseismology\, and astromet
 ry to infer precise stellar ages\, chemical abundances\, and dynamical hist
 ories across the Milky Way. I will particularly highlight scalable time-dom
 ain techniques for extracting stellar oscillations from large survey data\,
  transforming time-series observations into powerful constraints on Galacti
 c evolution. These approaches quantify the efficiency with which disk stars
  lose dynamical memory\, and show that the disk’s chemical bimodality likel
 y reflects a merger-driven origin linked to the formation of the Galactic b
 ar.\n\nI will conclude by outlining a path toward constructing a unified\, 
 multi-dimensional map of the Milky Way\, spanning spatial\, chemical\, dyna
 mical\, and temporal dimensions\, using datasets such as Euclid and Rubin L
 SST\, positioning time-domain and multi-modal data science at the centre of
  Galactic evolution studies.\n\nImported from https://www.physik.uni-heidel
