Horace B. Horton Professor Emeritus, University of Chicago, Department of Astronomy and Astrophysics


York's research deals with the dust and gas between the stars (the Galactic interstellar medium) and the same material in high redshift galaxies (the intergalactic medium, so called because we cannot see the galaxies themselves). Studies of local, Galactic material, where the physics can be studied in more detail, are used to develop techniques for studying galaxies at high redshifts.
