Cas A Supernova Remnant at 90 GHz!
Image of Cassiopiea A made with the MUSTANG 90 GHz bolometer Array on the GBT. MUSTANG is a 64 pixel focal plane array designed for the GBT. In September 2006 it became the first instrument to use the GBT at 90 GHz and it is also the GBT's first focal plane array.
With Recent improvements to the GBT surface and receiver stability, MUSTANG is currently capable of mapping a 3'x3' field to an RMS of 800 micro-Janskys/beam in 1 hr.
MUSTANG is a collaboration between the University of Pennsylvania and the NRAO, as well as NASA, The National Institute of Standards and Technology, and Cardiff University. More information is available at http://www.gb.nrao.edu/mustang/.
