Kuzma, Pete; Da Costa, Gary; Keller, Stefan; Maunder, Elizabeth

Description

In this paper, we present the results of a search for members of the globular cluster Palomar 5 and its associated tidal tails. The analysis has been performed using intermediate and low-resolution spectroscopy with the AAOmega spectrograph on the Anglo-Australian Telescope. Based on kinematics, line strength and photometric information, we identify 39 new red giant branch stars along ∼20° of the tails, a larger angular extent than has been previously studied. We also recover eight previously...[Show more]
