Constraining the Solar Galactic Reflex Velocity using Gaia Observations of the Sagittarius Stream
Constraining the Solar Galactic Reflex Velocity using Gaia Observations of the Sagittarius Stream
Because of its particular orientation around the Galaxy - i.e., in a plane nearly perpendicular to the Galactic plane and containing both the Sun and Galactic center - the Sagittarius (Sgr) stream provides a powerful means by which to measure the solar reflex velocity, and thereby infer the velocity of …
