Brief Introduction of Research
- I have conducted the “Galactic Archaeology” study. It has come into being over the last decade with the developments of sensitive wide-field imagers and spectrographs on medium and large optical telescopes, which is the study to reconstruct the stellar contents of the Milky Way and nearby galaxies from the detailed properties of the resolved stellar population in these systems. Resolved star studies of nearby galaxies have led to the discovery of vast stellar envelopes that are often rich in the substructure. These components are naturally predicted in models of hierarchical galaxy assembly, and their observed properties place important constraints on the amount, nature, and time history of satellite accretion to large galaxies.
