Accurate distances of the Galactic spiral arms from dust-scattered X-ray emission of gamma-ray bursts
B. Vaia, I. Fornasiero, A. Tiengo +5
The details of the spiral structure of the Milky Way are still debated due to large uncertainties in the distance estimates obtained through the most common tracers. X-ray dust sca…

Probing the interstellar medium toward GRB 221009A through X-ray dust scattering
B. Vaia, Ž. Bošnjak, A. Bracco +5
The observation of 21 X-ray dust-scattering rings around the extraordinarily bright gamma-ray burst (GRB) 221009A provides a unique opportunity to study the interstellar medium (IS…
