Accurate distances of the Galactic spiral arms from dust-scattered X-ray emission of gamma-ray bursts

The details of the spiral structure of the Milky Way are still debated due to the large uncertainties in the distance estimates obtained through the most common tracers. However, X-ray dust scattering rings produced by short extragalactic X-ray transients provide a direct method to measure the 3D di...
