    Julie Dahlstrom came to Carthage in 2009 from the University of Chicago, Yerkes Observatory, where she was a postdoctoral researcher in observational astrophysics, specializing in high-resolution spectroscopy of stars and interstellar clouds as well as the abundances of elements produced in the Big Bang. During her years as a researcher, she authored or co-authored more than 50 articles appearing in refereed scientific journals and conference proceedings. Professor Dahlstrom was awarded the 1995 Robert J. Trumpler award of the Astronomical Society of the Pacific for her dissertation research and a 1994 Hubble Postdoctoral Fellowship of the Space Telescope Science Institute.

    Professor Dahlstrom is engaged with Carthage students in collaborative research to identify the chemical constituents of the interstellar gases from which stars and planets form. Her primary research focus is on high-resolution spectroscopy of the “diffuse interstellar bands,” a series of signatures of as-yet-unidentified molecules. The diffuse interstellar bands problem is a classic and long-standing problem of observational astrophysics, known since the 1920s. Partners in this research include astrophysicists and chemists at the University of Chicago, the University of Illinois at Urbana-Champaign, the University of Colorado at Boulder, the Johns Hopkins University, Embry-Riddle Aeronautical University, and the Space Telescope Science Institute.

    In addition to teaching at Carthage, Professor Dahlstrom is a data specialist and instrument scientist for the Astrophysical Research Consortium’s echelle spectrograph on the 3.5m telescope at Apache Point Observatory in New Mexico. She retains close ties to Yerkes Observatory in Williams Bay, Wis., and has access to observational facilities there.
