Two chemically similar stellar overdensities on opposite sides of the plane of the Galactic disk

Two chemically similar stellar overdensities on opposite sides of the plane of the Galactic disk

<p>Our Galaxy is thought to have undergone an active evolutionary history dominated by star formation, the accretion of cold gas, and, in particular, mergers up to 10 gigayear ago. The stellar halo reveals rich fossil evidence of these interactions in the form of stellar streams, substructures...
