Broadband Imaging to Study the Spectral Distribution of Meteor Radio Afterglows
S. S. Varghese, J. Dowell, K. S. Obenberger +2
We present observations of 86 meteor radio afterglows (MRAs) using the new broadband imager at the Long Wavelength Array Sevilleta (LWA-SV) station. The MRAs were detected using th…
Detection of a Low-frequency Cosmic Radio Transient Using Two LWA Stations
S. S. Varghese, K. S. Obenberger, J. Dowell +1
We report the detection of a potential cosmic radio transient source using the two stations of the Long Wavelength Array. The transient was detected on 18 October 2017 08:47 UTC ne…
Testing the Radiation Pattern of Meteor Radio Afterglow
S. S. Varghese, K. S. Obenberger, G. B. Taylor +1
Radio emission from meteors or meteor radio afterglows (MRAs) were first detected using the all-sky imaging capabilities of the first station of the Long Wavelength Array (LWA1). I…
Bifrost: a Python/C++ Framework for High-Throughput Stream Processing in Astronomy
Miles D. Cranmer, Benjamin R. Barsdell, Danny C. Price +11
Radio astronomy observatories with high throughput back end instruments require real-time data processing. While computing hardware continues to advance rapidly, development of rea…
Rates, Flux Densities, and Spectral Indices of Meteor Radio Afterglows
K. S. Obenberger, J. D. Dowell, P. J. Hancock +4
Using the narrowband all-sky imager mode of the LWA1 we have now detected 30 transients at 25.6 MHz, 1 at 34 MHz, and 93 at 38.0 MHz. While we have only optically confirmed that 37…
Monitoring the Sky with the Prototype All-Sky Imager on the LWA1
K. S. Obenberger, G. B. Taylor, J. M. Hartman +8
We present a description of the Prototype All-Sky Imager (PASI), a backend correlator and imager of the first station of the Long Wavelength Array (LWA1). PASI cross-correlates a l…
