Chemo-Dynamical Evolution of Galaxies

Understand

Stars are fossils that retain the history of their host galaxies.

• Elements heavier than helium are created inside stars and are ejected when they die.
• From the spatial distribution of elements in galaxies, it is therefore possible to constrain the physical processes during galaxy formation and evolution.
• This approach, Galactic archaeology, has been popularly used for our Milky Way Galaxy with a vast amount of data from Gaia satellite and multi-object spectrographs to understand the origins of sub-structures of the Milky Way.
