Interstellar Chemistry with X-rays

X-ray spectroscopy can reveal the presence and abundance of heavy elements in space.  Many of these — including magnesium, silicon, iron, and oxygen — are widely suspected to be the main constituents of interstellar dust.  I will describe experiments that directly probe the composition of dust grains along the line of sight to luminous X-ray sources.

    I study dust with X-ray imaging and spectroscopy.  I keep an archive of select poster and presentation slides here.

    Please ask for permission before reusing my figures or illustrations.
