VLBI astrometry gives a 20.2 kpc distance and 872 pc height for G040.96+02.48, confirming a warp in the Extreme Outer Galaxy with unusual outward motion.
A local Tremaine-Weinberg framework integrates the continuity equation over flexible loops to measure galactic pattern speeds, recovering standard methods as special cases and validated on IllustrisTNG simulations.
Young giant stars reveal a flaring Milky Way disc with 3.5 kpc radial scale and extended spiral arms including a curved Perseus segment and a new Scutum-associated feature.
Revised radial-velocity response model including V_R,sin and V_R,cos applied to Milky Way kinematic data constrains spiral pitch angle to ~10°, density contrast 5-18%, and pattern speed 10-20 km/s/kpc.
