At 100 m, the GBT is the largest fully steerable telescope in the world. 485 ft 2.3 acre collecting area 305 ft
Characteristics of the GBT Large Collecting Area Sensitive to Low Surface Brightness Sky Coverage & Tracking (>85%) Angular Resolution Frequency Coverage Radio Quiet Zone Unblocked Aperture state-of-art receivers & detectors modern control software flexible scheduling The Advantage of Unblocked Optics Dynamic Range Near sidelobes reduced by a factor >10 from conventional antennas Gain & Sensitivity The 100 meter diameter GBT performs better than a 120 meter conventional antenna Reduced Interference
A telescope for cosmology The origin and destiny of the Universe Studying black holes and extreme environments to determine the fate and age of the Universe
A telescope for understanding galaxies Studying the formation and evolution of stellar systems “On the continuing formation of the Andromeda Galaxy: Detection of HI Clouds in the M31 Halo” Thilker et al 2004 ApJ “Neutral Hydrogen clouds in the M81/M82 Group” Chynoweth et al. 2008 AJ
A Telescope Designed to be Enhanced We have an ongoing development program to ensure the GBT remains a vibrant, cutting-edge instrument for years to come All development is done in conjunction with college & university groups around the country
