Science at Low Frequencies with the Long Wavelength Array

The Long Wavelength Array (LWA) is a new multi-purpose radio telescope operating in the frequency range 5-88 MHz with many different operational modes. Scientific programs include (1) the high-z universe, including distant radio galaxies and clusters - tools for understanding the earliest black holes and the cosmological evolution of Dark Matter and Dark Energy; (2) acceleration, propagation, and turbulence in the ISM, including the space-distribution and spectrum of Galactic cosmic rays and supernova remnants; (3) planetary, solar, and space science, including space-weather prediction and extra-solar planet searches; and (4) the radio transient universe including the recent discovery of self-emission from meteors.  The first station of the LWA, called LWA1, is located near the center of the VLA and has been operating for almost 5 years. A new station has begun operating at the Owens Valley Radio Observatory in California and a second station in New Mexcio is being commissioned.  We are now combining these stations with the new, wide-band, low frequency capability on the VLA.  I will discuss some early scientific results  and future prospects.
