OVRO-LWA

OVRO-LWA (for Owens Valley Long Wavelength Array) is a radio telescope at Owens Valley Radio Observatory (OVRO), California, consisting of an array of 352 dipole antennas. It began operation in 2013, with 256 antennas (essentially a duplicate of LWA1, which is a portion of the LWA located near the VLA in New Mexico). Subsequently, a substantial correlator (LEDA, Large-aperture Experiment to detect the Dark Age) has been added. One of its intended tasks is a line intensity mapping survey of the 21-cm line over 15 < z < 30.
