The detection of a 45° tidal stream associated with the globular cluster NGC 5466.

GRILLMAIR C.J. and JOHNSON R.

Abstract (from CDS):

We report on the detection in Sloan Digital Sky Survey data of a 45° tidal stream of stars, extending from Bootes to Ursa Major, which we associate with the halo globular cluster NGC 5466. Using an optimal contrast, matched-filter technique, we find a long, almost linear stellar stream with an average width of 1°.4. The stream is an order of magnitude more tenuous than the stream associated with Palomar 5. The stream's orientation on the sky is consistent to a greater or lesser extent with existing proper-motion measurements for the cluster.
