Evidence of a dwarf galaxy stream populating the inner Milky Way Halo

Understand

Stellar streams produced from dwarf galaxies provide direct evidence of the hierarchical formation of the Milky Way.

• Here, we present the first comprehensive study of the "LMS-1" stellar stream, that we detect by searching for wide streams in the Gaia EDR3 dataset using the STREAMFINDER algorithm.
• This stream was recently discovered by Yuan et al.
• (2020).
