Cosmology and the Stellar Halo
James S. Bullock, Kathryn V. Johnston
If the favored hierarchical cosmological model is correct, then the Milky Way system should have accreted and subsequently tidally destroyed ~100 low-mass galaxies in the past ~12…
Dark Matter Constraints from the Sagittarius Dwarf and Tail System
Steven R. Majewski, David R. Law, Kathryn V. Johnston +2
2MASS has provided a three-dimensional map of the >360 degree, wrapped tidal tails of the Sagittarius (Sgr) dwarf spheroidal galaxy, as traced by M giant stars. With the inclusion…
Measurements of Tidal Tail Populations Designed to Optimize Their Use as Potential Probes
Kathryn V Johnston
The launching of up to four astrometric missions in the next decade will enable us to make measurements of stars in tidal streamers from Galactic satellites of sufficient accuracy…
Evolution of the Galactic Potential and Halo Streamers with Future Astrometric Satellites
HongSheng Zhao, Kathryn Johnston, Lars Hernquist +1
ESA's Global Astrometric Interferometer for Astrophysics (GAIA) holds the promise of mapping out the detailed phase space structure of the Galactic halo by providing unprecedented…
The Role of Accretion in Forming the Galactic Halo
Kathryn V. Johnston
If the Galaxy formed hierarchically through the accretion of smaller satellite galaxies we might hope to find signatures of this in the halo's phase-space distribution. I review th…
