Description:

Title: Science at Low Frequencies with the Long Wavelength Array

Speaker: Greg Taylor, University of New Mexico

Host: Farhad Yusef-Zadeh

Abstract: 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) planetary, solar, and space science, including space-weather prediction and extra-solar planet searches; (3) studies of the Earth's ionosphere; 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 6 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 a number of scientific results and future prospects.
