UTAS People Involved
John Dickey is the professor of physics and astronomy, who arrived in July, 2004. John's research area is radio spectroscopy of the Milky Way and nearby galaxies. His specialty is 21-cm line studies of the atomic hydrogen in the interstellar medium. By comparing emission and absorption in the 21-cm line, Professor Dickey has derived the temperature of the interstellar gas in the Milky Way, the Magellanic Clouds, and in nearby galaxies such as M31 and M33. 

Professor Dickey is the principal investigator on the Southern Galactic Plane Survey, a large project to survey the 21-cm emission and absorption from the inner Milky Way galaxy using the Australia Telescope National Facility telescopes at Parkes and Narrabri, NSW, as well as Northern Hemisphere telescopes like the Very Large Array and Green Bank Telescope in the US and the Dominion Radio Astrophysical Observatory in Canada. This project has recently detected a spiral structure in the far outer galaxy that had not been identified before.
