GRB 180325A: dust grain-size distribution and interstellar iron nanoparticles contribution

Elizabeth Cappellazzo, Tayyaba Zafar, Pablo Corcho-Caballero +3

We modelled dust grain-size distributions for carbonaceous and silicates dust, as well as for free-flying iron nanoparticles in the environment of a $\gamma$-ray burst (GRB) afterglow,…
