The effect of feedback and reionization on star formation in low-mass dwarf galaxy haloes
Christine M. Simpson, Greg L. Bryan, Kathryn V. Johnston +4
We simulate the evolution of a 10^9 Msun dark matter halo in a cosmological setting with an adaptive-mesh refinement code as an analogue to local low luminosity dwarf irregular and…
A 2MASS All-Sky View of the Sagittarius Dwarf Galaxy: VII. Kinematics of the Main Body of the Sagittarius dSph
Peter M. Frinchaboy, Steven R. Majewski, Ricardo R. Munoz +5
We have assembled a large-area spectroscopic survey of giant stars in the Sagittarius (Sgr) dwarf galaxy core. Using medium resolution (R ~15,000), multifiber spectroscopy we have…
Identifying Local Group Field Galaxies which have interacted with the Milky Way
Maureen Teyssier, Kathryn V. Johnston, Michael Kuhlen
We distinguish between Local Group field galaxies which may have passed through the virial volume of the Milky Way, and those which have not, via a statistical compari- son against…
NGC 5466: a unique probe of the Galactic halo shape
H. Lux, J. I. Read, G. Lake +1
Stellar streams provide unique probes of galactic potentials, with the longer streams normally providing the cleaner measurements. In this paper, we show an example of a short tida…
Probing the Halo From the Solar Vicinity to the Outer Galaxy: Connecting Stars in Local Velocity Structures to Large-Scale Clouds
Kathryn V. Johnston, Allyson A. Sheffield, Steven R. Majewski +1
(Abridged) This paper presents the first connections made between two local features in velocity-space found in a survey of M giant stars and stellar spatial inhomogeneities on glo…
Identifying Contributions to the Stellar Halo from Accreted, Kicked-Out, and In Situ Populations
Allyson A. Sheffield, Steven R. Majewski, Kathryn V. Johnston +10
[Abridged] We present a medium-resolution spectroscopic survey of late-type giant stars at mid-Galactic latitudes of (30), designed to probe the properties…
