Candidate RR Lyr star streams in inner Galaxy

We find 2 RRLS stream candidates at >4{sigma} confidence and another 12 at >3.5{sigma} confidence over the Galactocentric distance range 4<D/kpc<26. Of these, only two are associated with known globular clusters (NGC 1261 and Arp2).

The remainder are candidate 'orphan' streams, consistent with the idea that globular cluster streams are most visible close to dissolution. Our detections are likely a lower bound on the total number of dissolving globulars in the inner galaxy, since many globulars have few RRLSs, while only the brightest streams are visible over the Galactic RRLS background, particularly given the current lack of kinematical information.
