个人简介
His research has centred on studying stars in the Galaxy to understand its structure and evolutionary history.
Gilmore moved to the Institute of Astronomy of the University of Cambridge in 1984 on being awarded an advanced research fellowship by the Science and Engineering Research Council.
He used observations of spectra of stars to study the structure of the Galaxy, particularly by measuring their radial velocities. Working with Konrad Kuijken, he used spectra of faint stars in the region around the South Galactic Pole obtained with the Anglo-Australian Telescope to measure the stars' radial velocities, and consequently to determine the surface mass density of the Galactic disc. They showed that there was little or no dark matter within the disc other than that part of the Galactic dark matter halo that extends through the disc. Consequently, dark matter within the Galaxy does not concentrate within the disc.
