![]() ![]() The combination of its fully steerable 100-m unblocked aperture which provides an extremely clean point spread function allowing high dynamic range observations of diffuse emission, active surface that can maintain an RMS surface accuracy of 230 microns, 0.29–116 GHz nearly continuous frequency coverage with low-noise radio receivers, flexible instrumentation, the ability to observe declinations as low as -47°, and location in two different interference protection zones are not found in any other single telescope. Byrd Green Bank Telescope (GBT) is a unique resource for the US and global astronomical communities. While the current technical specifications are under discussion, the final instruments may have the characteristics outlined on this page. This will enable deeper, high resolution studies of cosmology, galaxy clusters, star forming regions, and the Galactic plane. 600-Pixel W-Band Bolometer (MUSTANG-3, Continuum) –MUSTANG-3 will operate from 75-105 GHz with full polarization, mapping 19 times faster than and have double the FOV of MUSTANG-2.144-Pixel W-band Array (Argus144, Spectral Lines) – Argus-144 will deliver high-fidelity maps of fundamental transitions of molecules that are sensitive tracers of gas covering a wide range of physical conditions, over spatial scales ranging from the sub-parsec thickness of filaments and dense cores in our own Galaxy, to the ~100 pc size of molecular clouds in the spiral arms of nearby galaxies.Mapping these transitions on a large scale is crucial for understanding star formation processes but requires prohibitively large amounts of telescope time using existing hardware. ![]() 225-Pixel K-Band Phased Array Feed (KPAF) – The KPAF will simultaneously observe the (1,1), (2,2), and (3,3) inversion transitions of ammonia, a critically important probe of dense molecular gas.Ku-Band Radar Transmitter (ngRADAR) – The ngRADAR will enable high resolution imaging of the Moon and planetary bodies, physical characterization of space debris, and detection and characterization of near-Earth asteroids.40-Pixel L-band Phased Array Feed (ALPACA) – ALPACA on the GBT will enable searches for pulsars as well as diffuse HI mapping with both high sensitivity and high dynamic range over a wide field of view.Please make your voice heard at this link. The Green Bank Observatory is currently conducting a survey on what new instruments the community would like to have available on the GBT.
