Tracing galaxy formation with stellar halos. I. Methods

JS Bullock, KV Johnston - The Astrophysical Journal, 2005 - iopscience.iop.org
If the favored hierarchical cosmological model is correct, then the Milky Way system should
have accreted~ 100-200 luminous satellite galaxies in the past~ 12 Gyr. We model this …

The origin of accreted stellar halo populations in the Milky Way using APOGEE, Gaia, and the EAGLE simulations

JT Mackereth, RP Schiavon, J Pfeffer… - Monthly Notices of …, 2019 - academic.oup.com
Recent work indicates that the nearby Galactic halo is dominated by the debris from a major
accretion event. We confirm that result from an analysis of APOGEE-DR14 element …
