Candidate Milky Way satellites in the Galactic halo.


Abstract (from CDS):

Sloan Digital Sky Survey (SDSS) DR5 photometric data with 120°<α<270°, 25°<δ<70° were searched for new Milky Way companions or substructures in the Galactic halo. Five candidates are identified as overdense faint stellar sources that have color-magnitude diagrams similar to those of known globular clusters, or dwarf spheroidal galaxies. The distance to each candidate is estimated by fitting suitable stellar isochrones to the color-magnitude diagrams. Geometric properties and absolute magnitudes are roughly measured and used to determine whether the candidates are likely dwarf spheroidal galaxies, stellar clusters, or tidal debris. SDSSJ1000+5730 and SDSSJ1329+2841 are probably faint dwarf galaxy candidates while SDSSJ0814+5105, SDSSJ0821+5608, and SDSSJ1058+2843 are very likely extremely faint globular clusters. Follow-up study is needed to confirm these candidates.
