Is Ursa Major II the Progenitor of the Orphan Stream?
M. Fellhauer, N. W. Evans, V. Belokurov +9
Prominent in the `Field of Streams' -- the Sloan Digital Sky Survey map of substructure in the Galactic halo -- is an `Orphan Stream' without obvious progenitor. In this numerical…
The Influence of Mass-Loss from a Star Cluster on its Dynamical Friction -- I. Clusters without Internal Evolution
M. Fellhauer, D. N. C. Lin
Many Local Group dwarf spheroidal galaxies are found in the Galactic halo along great circles in the sky. Some of these stellar systems are thought to be the fragments of larger pa…
Complex stellar populations in massive clusters: trapping stars of a dwarf-disc galaxy in a newborn stellar super-cluster
Mike Fellhauer, Pavel Kroupa, Wyn Evans
Some of the most massive globular clusters of our Milky Way, such as for example omega-Centauri, show a mixture of stellar populations spanning a few Gyr in age and 1.5 dex in meta…
A Curious New Milky Way Satellite in Ursa Major
D. B. Zucker, V. Belokurov, N. W. Evans +29
In this Letter, we study a localized stellar overdensity in the constellation of Ursa Major, first identified in Sloan Digital Sky Survey (SDSS) data and subsequently followed up w…
The Origin of the Bifurcation in the Sagittarius Stream
M. Fellhauer, V. Belokurov, N. W. Evans +9
The latest Sloan Digital Sky Survey data reveal a prominent bifurcation in the distribution of debris of the Sagittarius dwarf spheroidal (Sgr) beginning at a right ascension of ro…
An Orphan in the "Field of Streams"
V. Belokurov, N. W. Evans, M. J. Irwin +19
We use Sloan Digital Sky Survey Data Release 5 photometry and spectroscopy to study a tidal stream that extends over 50 degrees in the North Galactic Cap. From the analysis of the…
