Catalog of 1,573 molecular clouds with robust distances from 150 to 3000 pc determined by matching CO intensity maps to dust extinction maps, 90% measured for the first time with ~20% statistical and ~10% systematic uncertainties.
New VLBA parallaxes for four masers refine the Perseus arm position and pitch angle in the first Galactic quadrant, with extrapolation showing intersection with the Sagittarius arm at 200° azimuth and 5.6 kpc radius.
Perspective outlining how SKA-VLBI will map the Milky Way's full spiral structure and constrain Galactic parameters using high-precision maser astrometry.
