Long Wavelength Demonstrator Array

The Long Wavelength Array is a collection of 256 antennas stationed at the Very Large Array site outside Magdalena, New Mexico. It is a low-frequency radio telescope designed to produce high-sensitivity, high-resolution images in the frequency range of 10-88 MHz. This station is one of several, giving the entire LWA project e a large collecting area (up to 1 square kilometer at its lowest frequencies) spread over an array with baselines up to at least 400 km. With long wavelengths, astronomers can learn more about Dark Energy and Dark Matter, hunt for the earliest hydrogen back in the young Universe, and hunt for planets around other stars.

The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
	The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progess of science; to advance the national health, prosperity, and welfare; to secure the national defense..."
	AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
