Bar-driven Streaming Motions Mimic a Massive Bulge in the Inner Milky Way

The circular speed curve of the Milky Way provides a key constraint on its mass distribution, reflecting the axisymmetric component of the gravitational potential. This is especially critical in the inner Galaxy ( R  ≲ 4 kpc), where nonaxisymmetric structures, such as the stellar bar and nuclear ste...
