A comprehensive model for the Monoceros tidal stream
J. Penarrubia, D. Martinez-Delgado, H. W. Rix +7
We have compiled an extensive dataset on potential parts of the Monoceros tidal stream and performed an exhaustive survey of dwarf galaxy semi-analytic orbits in order to constrain…
The Third Data Release of the Sloan Digital Sky Survey
K. Abazajian et al.
This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through June 2003, includes imaging data in five bands ov…
The Closest View of a Dwarf Galaxy: New Evidence on the Nature of the Canis Major over-density
David Martinez-Delgado, David J. Butler, Hans-Walter Rix +4
We present a first deep colour-magnitude diagram of the putative central region (0.5 deg x 0.5 deg) of the Canis Major stellar over-density (l,b)=(240,-8) found by Martin et al. (2…
Mapping Tidal Streams around Galactic Globular Clusters
David Martinez-Delgado, Dana I. Dinescu, Robert Zinn +3
The surroundings of globular clusters in the outer halo are one of the best places to look for the remnants of ancient dwarf satellites. The classical Searle & Zinn (1978) scenario…
Mass Segregation in the Globular Cluster Palomar 5 and its Tidal Tails
A. Koch, E. K. Grebel, M. Odenkirchen +2
We present the stellar main sequence luminosity function (LF) of the disrupted, low-mass, low-concentration globular cluster Palomar 5 and its well-defined tidal tails, which emana…
Andromeda IX: A New Dwarf Spheroidal Satellite of M31
Daniel B. Zucker, Alexei Y. Kniazev, Eric F. Bell +19
We report the discovery of a new dwarf spheroidal satellite of M31, Andromeda IX, based on resolved stellar photometry from the Sloan Digital Sky Survey (SDSS). Using both SDSS and…
