Shiva and Shakti: Presumed Proto-Galactic Fragments in the Inner Milky Way
The Astrophysical JournalUsing Gaia Data Release 3 astrometry and spectroscopy, we study two new substructures in the orbit–metallicity space of the inner Milky Way: Shakti and Shiva.

Evaluating Classifications of Extremely Metal-poor Candidates Selected from Gaia XP Spectra
The Astronomical JournalExtremely metal-poor stars are intrinsically rare, but emerging methods exist to accurately classify them from all-sky Gaia XP low-resolution spectra.

How to Build an Empirical Speed Distribution for Dark Matter in the Solar Neighborhood
The Astrophysical JournalThe dark matter flux in a direct detection experiment depends on its local speed distribution. This distribution has been inferred from simulations of Milky Way–like galaxies, but such models serve only as proxies, given that no simulation directly ...

Galactic archaeology and its application to the galactic center
L’archéologie galactique et son application au centre galactique L'archéologie galactique consiste à disséquer et analyser les nombreuses composantes de la Voie Lactée afin de mettre en évidence et distinguer les processus physiques qui contribuent à sa formation et son évolution.

Galactic Archaeology in the Bulge : in the era of Gaia & Large Spectroscopic Surveys
, 2019 The lack of large samples of high-resolution spectra of individual stars tracing large areas around the Galactic Bulge and inner-most regions of the Galaxy has been a long-standing missing information piece. This has prevented so far a clearer picture of

Asteroseismology of Metal-poor Red Giants Observed by TESS
The Astrophysical JournalGalactic archeology has long been limited by a lack of precise masses and ages for metal-poor stars in the Milky Way’s thick disk. However, with TESS providing a growing number of photometric observations, it is possible to calculate masses and ages for ...
