| Abstract: | The Long Wavelength Array (LWA) would be a new multi-purpose radio telescope operating in the frequency range 10-88 MHz with angular resolution of a few arcseconds. Scientific programs would 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, respectively; (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 GRBs and new sources of unknown origin. The first station of the LWA, called LWA1 or LWA_VL, is located near the center of the VLA and has been operating for over a year. The new LWA_OVRO station (located at the Owens Valley Radio Observatory) has just been completed. We have also developed basic station infrastructure and have 32 antenna stands at LWA_NA (located near the end of the VLA's North Arm) and have begun to similarly develop LWA_SV (located on the Sevilleta Wildlife Refuge north of Socorro). There may also be a possiblity to combine these stations with the new, wide-band, low frequency capability on the VLA. I will discuss how these activities might be used to optimally design the LWA, and how we plan to carry out scientific observations every step on the way to the LWA. | |
