The Rich Are Different: Evidence from the RAVE Survey for Stellar Radial Migration
G. Kordopatis, J. Binney, G. Gilmore +21
Using the RAdial Velocity Experiment fourth data release (RAVE DR4), and a new metallicity calibration that will be also taken into account in the future RAVE DR5, we investigate t…
Characterizing the High-Velocity Stars of RAVE: The Discovery of a Metal-Rich Halo Star Born in the Galactic Disk
K. Hawkins, G. Kordopatis, G. Gilmore +21
We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). W…
Interaction between the IGM and a dwarf galaxy
V. Lora, A. C. Raga, E. K. Grebel
Dwarf Galaxies are the most common objects in the Universe and are believed to contain large amounts of dark matter. There are mainly three morphologic types of dwarf galaxies: dwa…

Discovery of a stellar tidal stream around the Whale galaxy, NGC 4631
David Martinez-Delgado, Elena D'Onghia, Taylor S. Chonis +5
We report the discovery of a giant stellar tidal stream in the halo of NGC 4631, a nearby edge-on spiral galaxy interacting with the spiral NGC 4656, in deep images taken with a 40…
The Panchromatic High-Resolution Spectroscopic Survey of Local Group Star Clusters - I. General Data Reduction Procedures for the VLT/X-shooter UVB and VIS arm
Frederik Schönebeck, Thomas H. Puzia, Anna Pasquali +5
Our dataset contains spectroscopic observations of 29 globular clusters in the Magellanic Clouds and the Milky Way performed with VLT/X-shooter. Here we present detailed data reduc…
