John Dickey is a new
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.
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.
