Abstract

Using integral field data we extract the optical spectra of shocked interstellar clouds in Kepler’s supernova remnant located in the inner regions of our Galaxy, as well as in the Large Magellanic Cloud, the Small Magellanic Cloud, NGC 6822, and IC 1613. Using self-consistent shock modeling, we make a new determination of the chemical composition of the interstellar medium in N, O, Ne, S, Cl, and Ar in these galaxies and obtain accurate estimates of the fraction of refractory grains destroyed in the shock.
