Center for Astrophysics Research and Technologies Seminar Series
Long Wavelength Array Instrument Development for Time-Domain Radio Astronomy
Presented by Craig Taylor (UNM)
To continue pushing the cutting edge in radio astronomy instrumentation, constant upgrades must be made to active telescopes to best take advantage of emerging technologies with the capability to expand observable parameter spaces. Here I present my contributed, and ongoing, work to upgrade existing Long Wavelength Array (LWA) architectures in the E-field Parallel Imaging Correlator (EPIC) project. To better verify the imaging products produced by this novel direct radio imaging implementation, source localization and direct image comparison is used to diagnose errors in the EPIC software implementation. I also present updates to work on the design and construction of a new experimental LWA 'mini-station' that will serve as a test case for a cost-efficient, rapidly deployable dipole array telescope. This will be a powerful instrument for the discovery of radio transients including meteor radio afterglows, fast radio bursts, flare stars and potentially new classes of radio sources.
