The Long Wavelength Array

Welcome to the LWA

The Long Wavelength Array (LWA) is a radio telescope operating between 10 MHz and 88 MHz, exploring the Universe at the lowest frequencies observable from the ground. Located in central New Mexico, the LWA currently consists of three stations—LWA1, LWA-SV, and LWA-NA—operated by the University of New Mexico. The LWA is open for astronomical observations and proposals are accepted on a regular basis.

Looking ahead, the LWA Swarm concept will expand the array into a continental-scale instrument by distributing stations to universities and colleges across the US, achieving sub-arcsecond resolution through very long baseline interferometry.

We operate a cluster that is kindly hosted by NRAO in the old correlator room. Information about the OVRO-LWA station run by Caltech can be found here.
