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…
Is the sky falling? Searching for stellar streams in the local Milky Way disc in the CORAVEL and RAVE surveys
G. M. Seabroke, G. Gilmore, A. Siebert +19
We have searched for in-falling stellar streams on to the local Milky Way disc in the CORAVEL and RAVE surveys. The CORAVEL survey consists of local dwarf stars (Nordstrom et al. G…
