Galactic Archaeology in the Local Group

open access: yes, 2020
We are in the age of advanced surveys and simulations which have greatly expanded our understanding of the large scale evolution of the universe, but have also revealed many contradictions at small scale. Limitations of our simulations make it difficult to resolve faint substructures in Local Group analogs, hence we resort to observations which now ...

Constructing a Pristine View of Extended Globular Cluster Structure

open access: yesThe Astronomical Journal
Globular clusters (GCs) displaying extended structures are becoming increasingly ubiquitous in the Milky Way (MW). Despite their low surface brightness, which makes disentangling the true structure from the MW overwhelming difficult, the increasing ...

Machine Learning Techniques to Distinguish Giant Stars from Dwarf Stars Using Only Photometry—Pushing Redward

open access: yesThe Astronomical Journal
We present our photometric method, which combines Subaru/Hyper Suprime-Cam N B 515, g -band, and i- band filters to distinguish giant stars in Local Group galaxies from Milky Way dwarf contamination.

Galactic archaeology and its application to the galactic center

open access: yes, 2018
Galactic archaeology deals with dissecting the Milky Way into its various components with the objective to disentangle processes contributing to the Milky Way formation and evolution. This relies on precise estimation of positions, velocities as well as stellar atmosphere properties of individual stars belonging to different stellar populations that ...

A Million Three-body Binaries Caught by Gaia

open access: yesThe Astrophysical Journal
Gaia observations have revealed over a million stellar binary candidates within ∼1 kpc of the Sun, predominantly characterized by orbital separations >10 ^3 au and eccentricities >0.7.
