Planetary and Solar Radio Emission Studies with the Long Wavelength Array (Abstract)
Abstract
Sub-arcminute resolution and sub-Jy sensitivity below 100 MHz is now being obtained on a routine basis with the 74 MHz system on the NRAO Very Large Array (VLA). These dramatic improvements result from the development and application of self-calibration and field-based calibration techniques. The VLA 74 MHz breakthrough has inspired an emerging suite of new low frequency instruments, most notably the Long Wavelength Array (LWA), an electronic array planned to operate in the 20-80 MHz frequency range. It will have a collecting area approaching one square kilometer at its lowest operating frequencies, and provide milliJansky sensitivity and a few arcseconds resolution across its observing band. The LWA will surpass, by 2-3 orders of magnitude, the imaging power of previous interferometers in its frequency range, and thus open a window on one of the most poorly explored regions of the electromagnetic spectrum.
