Abstract

We report the discovery of tidal tails around the Galactic globular cluster NGC 7492, based on the Data Release 1 of the Pan-STARRS1 survey. The tails were detected using a version of the matched filter technique applied to the (g - r, r) and (g - i, i) color-magnitude diagrams. Tidal tails emerging from the cluster extend at least ∼3.°5 in the north-east to south-east direction, equivalent to ∼1.5 kpc in projected length.
