The Fimbulthul stellar stream was tidally stripped from the globular cluster ω Centauri

The Milky Way Galaxy formed in part through the accretion of smaller dwarf galaxies. Some of these events remain imprinted on the Galaxy in the form of stellar tidal streams: coherent kinematic and spatial structures of stars. The discovery of these streams has exploded recently thanks to deep photometric surveys (e.g., DES, Pan-STARRS) combined with the precise kinematic information from Gaia. One particular stream, Fimbulthul, has associated with the massive globular cluster ω Centauri[1, 2], but only with kinematics and metallicities. In this talk, I will use the abundance information from the GALAH survey to confirm this association of the Fimbulthul stellar stream to ω~Centauri using chemical tagging from over 10 elements with a range of dominant nucleosynthetic origins.
