The kinematic footprints of five stellar streams in Andromeda's halo
S. C. Chapman, R. Ibata, M. Irwin +12
(abridged) We present a spectroscopic analysis of five stellar streams (`A', `B', `Cr', `Cp' and `D') as well as the extended star cluster, EC4, which lies within streamC, all disc…
The Radial Velocity Experiment (RAVE): second data release
T. Zwitter, A. Siebert, U. Munari +51
We present the second data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities (RVs) and stellar atmosphere parameters…
The ghost of a dwarf galaxy: fossils of the hierarchical formation of the nearby spiral galaxy NGC 5907
David Martinez-Delgado, Jorge Penarrubia, R. Jay Gabany +3
We present an extragalactic perspective of an extended stellar tidal stream wrapping around the edge-on, spiral galaxy NGC 5907. Our deep images reveal for the first time a large s…
Kinematics of Stars in Kapteyn Selected Area 71: Sampling the Monoceros and Sagittarius Tidal Streams
Dana I. Casetti-Dinescu, Jeffrey L. Carlin, Terrence M. Girard +3
We present a 3D kinematical analysis of stars located in Kapteyn Selected Area 71 (l = 167.1, b = -34.7), where previously a stellar excess was found (Dinescu et al. 2002, Newberg…
Discovery of a Giant Stellar Tidal Stream Around the Disk Galaxy NGC 4013
David Martinez-Delgado, Michael Pohlen, R. Jay Gabany +3
We report the discovery of a giant, loop-like stellar structure around the edge-on spiral galaxy NGC 4013. This arcing feature extends 6 arcmin (~26 kpc in projected distance) nort…
