Dust scattering halo of 4U 1630-47: High resolution X-ray and mm observations constrain source and molecular cloud distances
E. Kalemci, M. DÃaz Trigo, E. Oztaban +8
We re-investigated the distance to the black hole X-ray binary 4U 1630-47 by analyzing its dust scattering halo (DSH) using high-resolution X-ray (Chandra) and millimeter (APEX) ob…
