Galactic stellar populations in the era of the sloan digital sky survey and other large surveys
Studies of stellar populations, understood to mean collections of stars with common spatial,
kinematic, chemical, and/or age distributions, have been reinvigorated during the past …

The Virgo Overdensity Explained
T Donlon, HJ Newberg, J Weiss, P Amy… - The Astrophysical …, 2019 - iopscience.iop.org
We suggest that the Virgo Overdensity of stars in the stellar halo is the result of a radial dwarf
galaxy merger that we call the Virgo Radial Merger. Because the dwarf galaxy passed very …

Constraining the Milky Way halo shape using thin streams
Tidal streams are a powerful probe of the Milky Way (MW) potential shape. In this paper, we
introduce a simple test-particle method to fit stream data, using a Markov Chain Monte Carlo …
