SUMMARY:S&A Colloquium: Nivedita Mahesh (California Institute of Technology)
DESCRIPTION:The Frontier in Low Frequency Radio Astrophysics from the Farside of the Moon\n\nAbstract\n\nThe Farside Array for Radio Science Investigations of the Dark ages and Exoplanets (FARSIDE) is a NASA Probe-class concept to place a low-frequency radio interferometric array on the far side of the Moon. FARSIDE will look for radio emissions from magnetospheres of stars and exoplanets\, which affect exoplanet habitability and serve as a pathfinder for studying the Dark Ages of the Universe. The FARSIDE architecture employs a novel design consisting of 128 pairs of antennas and receiver nodes distributed over a 10 km × 10 km area in a four-arm spiral configuration that will operate from 200 kHz to 40 MHz. I will present the planned mission architecture\, array layout\, antenna packaging\, and deployment trade study. In addition\, this talk will cover the projected performance and sensitivity of the array for the two primary sciences cases. Given the novel deployment strategy for the FARSIDE array\, we have developed a forward modeling pipeline to simulate its polarization performance. This lunar array concept is developed a lot on the heritage of a similar low frequency telescope on ground – the OVRO Long Wavelength Array. And I will briefly discuss the current status and pipeline development efforts of the newly upgraded OVRO-LWA. The talk will end with an overview of one of humanities’ next “great” observatories – FarView – a NASA Innovative Advanced Concepts. Farview will be an observatory built in-situ on the lunar farside using materials from regolith. \n\n \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia
