STREAMFINDER: Detection of a new stellar stream in the Pan-STARRS survey


Abstract:
STREAMFINDER is a new algorithm that we have built to detect stellar streams in an automated and systematic way in astrophysical datasets that possess any combination of positional and kinematic information. I will establish that the algorithm is capable of detecting ultra-faint and distant halo stream structures in the Gaia-like dataset. Further, I will present the workings of the STREAMFINDER with real proper motion data from the Pan-STARRS1 survey by demonstrating an "improved detection" of the so called "GD-1" stream structure. Moreover, we also discovered a new stream structure in the neighbouring region of GD-1. This new structure will be discussed in the talk as well.
