| Abstract: |
The Long Wavelength Array (LWA) will be a new multi-purpose radio telescope operating in the frequency range 10-88 MHz. Scientific programs include pulsars, supernova remnants, general transient searches, radio recombination lines, solar and Jupiter bursts, investigations into the "dark ages" using redshifted hydrogen, and ionospheric phenomena. The first station of the LWA, called "LWA1", is located near the center of the VLA and has recently begun scientific operations as a stand-alone instrument with collecting area roughly equivalent to a 100m dish. The LWA1 images the sky in realtime using the "transient buffer - narrowband" (TBN) system which is operational with 256 dipoles, and a bandwidth of 70 kHz. The LWA1 can also form up to 4 beams on the sky simultaneously with 16 MHz bandwidth in each of two tunings and full polarization. Early results include observations of pulsars, the Sun, and Jupiter. The LWA1 is supported by NSF as a University Radio Observatory and as such is open for use by the community. |
