Determining the Dust Extinction of Gamma-Ray Burst Host Galaxies: A Direct Method Based on Optical and X-Ray Photometry

The dust extinction of gamma-ray burst (GRB) host galaxies, which contains important clues to the nature of GRB progenitors and is crucial for dereddening, is still poorly known. Here we propose a straightforward method for determining the extinction of GRB host galaxies by comparing the observed op...
