The discovery of tidal tails around the globular cluster NGC 5466

We report the discovery of tidal tails around the high-latitude Galactic globular cluster NGC 5466 in Sloan Digital Sky Survey data. Neural networks are used to reconstruct the probability distribution of cluster stars in ugriz space. The tails are clearly visible once extragalactic contaminants and field stars have been eliminated. They extend similar to 4 degrees on the sky, corresponding to similar to 1 kpc in projected length. The orientation of the tails is in good agreement with the cluster's Galactic orbit, as judged from the proper-motion data.
