the Universe in Absorption

As the light from bright, distant objects traverse the Universe, intervening gas clouds---between, around, and in galaxies---absorb the light at wavelengths characteristic, albeit redshifted, of the elements in the clouds. By identifying and modeling the elements associated with absorption systems, Dr. Kathy Cooksey from the Massachusetts Institute of Technology will explain how we learn about how gas is processed through and dispersed from galaxies over cosmic time.
