STATE INTERVENTIONISM IN THE LATE CLASSIC MAYA PALENQUE POLITY: HOUSEHOLD AND COMMUNITY ARCHAEOLOGY AT EL LACANDON [PDF]

, 2013
Archaeological materials from seven excavated households (three commoner, three elite and a super-elite) from El Lacandón, a rural settlement of the Ancient Maya Palenque polity in Chiapas, Mexico; are analyzed to examine how households and communities ...

Cosmological Simulations of Stellar Halos with Gaia Sausage–Enceladus Analogs: Two Sausages, One Bun?

The Astrophysical Journal
Observations of the Milky Way’s stellar halo find that it is predominantly comprised of a radially biased population of stars, dubbed the Gaia Sausage–Enceladus, or GSE.

Dynamical Origins of Azimuthal Metallicity Variations in the Galactic Disk: Insights from Kinematic Ridges with Gaia

The Astrophysical Journal
Kinematic and spectroscopic studies in the past few years have revealed coherent azimuthal metallicity variations across the disk of the Milky Way (MW) that may be the result of dynamical process associated with nonaxisymmetric features of the Galaxy. At

Stellar Ages for Galactic Archaeology [Elektronisk resurs] : Methods and Applications

, 2021
Galactic Archaeology is the study of the formation and evolution of the Milky Way through the properties of stars and stellar populations. The combination of stellar ages, chemical compositions, positions, and velocities can reveal the history of star ...
