An analytical phase-space model for tidal caustics
Robyn E. Sanderson, Amina Helmi
The class of tidal features around galaxies known variously as "shells" or "umbrellas" comprises debris that has arisen from high-mass-ratio mergers with low impact parameter; the…
The properties of the local spiral arms from RAVE data: two-dimensional density wave approach
A. Siebert, B. Famaey, J. Binney +19
Using the RAVE survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely origina…
The satellites of the Milky Way - Insights from semi-analytic modelling in a LambdaCDM cosmology
Else Starkenburg, Amina Helmi, Gabriella De Lucia +7
We combine the six high-resolution Aquarius dark matter simulations with a semi-analytic galaxy formation model to investigate the properties of the satellites of Milky Way-like ga…
Nucleosynthesis and the Inhomogeneous Chemical Evolution of the Carina Dwarf Galaxy
Kim Venn, Matthew Shetrone, Mike Irwin +12
The detailed abundances of 23 elements in nine bright RGB stars in the Carina dSph are presented based on high resolution spectra gathered at the VLT and Magellan telescopes. A sph…
