Info

Use the Milky Way as radiation source - X-ray spectrum of stars known - On earth we can see what is absorbed
The role of <strong>DUBBLE</strong>: • The dust is iron rich • Pure, amorphous or crystalline iron silicates • Calculate the EXAFS spectrum as function of position in Milky Way • Different position, different dust??? • Very accurate EXAFS calibration spectra required <strong>DUBBLE</strong>
