Green Bank Telescope
(GBT, GB, Robert C. Byrd Green Bank Telescope)
(West Virginia large radio telescope)
The Green Bank Telescope (GBT, sometimes further
abbreviated as GB) is a 100-meter
radio telescope at Green Bank Observatory (GBO) in West Virginia.
The GBO was previously a part of the NRAO
(initially, its primary site),
but has been independent since 2016.
The GBT is the world's largest steerable telescope.
The current telescope was completed in 2000,
replacing the earlier, collapsed, 1962 Green Bank 300ft Telescope (GB300)
(likely in its own time called the "Green Bank Telescope").
The current telescope detects frequencies in the range of
290 MHz to 100 GHz, with prime focus and Gregorian
receivers, the former for the longer wavelengths.
The reflector is off-axis such that the receivers
do not block it.
Among its present/past instruments:
Back end instruments have included VEGAS
(Versatile GBT Astronomical Spectrometer)
and GUPPI.
Recent projects include 21-cm line surveys both within the
Milky Way, and extragalactic, e.g., redshifted
galaxies and also intensity mapping the DEEP2
field.
