Cosmic Rays and the Interstellar Medium
Published online by Cambridge University Press: 25 April 2016
Extract
Absorption limits the distances at which X-ray sources may be observed at low photon energies (≲3 keV). Several authors have estimated the X-ray absorption coefficients of the interstellar medium by assuming a chemical composition such as that given by Aller for the general abundances of the elements.
