Virgo cluster early-type dwarf galaxies with the Sloan Digital Sky Survey. IV. The color-magnitude relation
Thorsten Lisker, Eva K. Grebel, Bruno Binggeli
We present an analysis of the optical colors of 413 Virgo cluster early-type dwarf galaxies (dEs), based on Sloan Digital Sky Survey imaging data. Our study comprises (1) a compari…
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…
A Wide-Field View of Leo II -- A Structural Analysis Using the SDSS
Matthew G. Coleman, Katrin Jordi, Hans-Walter Rix +2
Using SDSS I data, we have analysed the stellar distribution of the Leo II dwarf spheroidal galaxy (distance of 233 kpc) to search for evidence of tidal deformation. The existing S…
The metallicity extremes of the Sagittarius dSph using SALT spectroscopy of PNe
A. Kniazev, A. Zijlstra, E. Grebel +10
In this work we present the first spectroscopic results obtained with the Southern African Large Telescope (SALT) telescope during its perfomance-verification phase. We find that t…
The accretion origin of the Milky Way's stellar halo
Eric F. Bell, Daniel B. Zucker, Vasily Belokurov +15
We have used data from the Sloan Digital Sky Survey (SDSS) Data Release 5 to explore the overall structure and substructure of the stellar halo of the Milky Way using about 4 milli…
Stellar kinematics in the remote Leo II dwarf spheroidal galaxy -- Another brick in the wall
A. Koch, J. T. Kleyna, M. I. Wilkinson +5
We present the projected velocity dispersion profile for the remote (d=233kpc) Galactic dwarf spheroidal (dSph) galaxy Leo II, based on 171 discrete stellar radial velocities that…
