Research Interests & Projects
Tim is actively studying the role of magnetic fields in the structure and physics of the interstellar medium, both in our own Milky Way Galaxy and in other galaxies far, far away. He employs the spectropolarimetric tools of Zeeman splitting and Faraday rotation to detect magnetic fields via radio emission from a diverse set of astrophysical environments. These include such objects as molecular and atomic gas clouds in the Milky Way, galaxies undergoing intense high-mass star formation, and distant galaxies whose interstellar matter has been ionized. Tim specializes in single-dish radio astronomy and currently uses the 26-m John A. Galt Telescope at the DRAO, the 64-m Parkes Radio Telescope, the 100-m Robert C. Byrd Green Bank Telescope, and the 305-m William E. Gordon Arecibo Telescope. Tim also uses the multi-element Karl G. Jansky Very Large Array and the Very Long Baseline Array in order to study the magnetic fields in other galaxies at high spatial resolution.
