Flipping of the tidal tails of the Ophiuchus stream due to the decelerating Galactic bar
Yong Yang, Geraint F. Lewis, Denis Erkal +16
The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shor…
