The EDD Radio Astronomy Backend Framework

Ewan D. Barr, Amit Bansod, Jan Behrend +16

Modern digital radio astronomy receivers produce increasingly wide-bandwidth, high bit-rate data streams that necessitate the development of flexible, scalable, and maintainable ba…

Sensitivity of a closed dielectric haloscope to axion dark matter

A. Ivanov, D. Leppla-Weber, B. Ary dos Santos Garcia +40

We present a method to determine the sensitivity of a closed dielectric haloscope to axion dark matter. Dielectric haloscopes aim to probe the theoretically well-motivated axion ma…

MeerKAT observations of the spiral galaxy NGC 2997 in the S band. Detection of high dynamo modes

A. Damas-Segovia, R. Beck, S. A. Mao +18

We seek to exploit the expanded observational range of the MeerKAT radio telescope with the new S-band receivers (2.0-2.8 GHz). To showcase its enhanced capabilities, we conducted…

Detection of OH maser emission in the 71-year periodic comet 12P/Pons-Brooks using the 40-m Thai National Radio Telescope (TNRT)

Nobuyuki Sakai, Saran Poshyachinda, Koichiro Sugiyama +44

Although the optical cometary database is extensive, the radio database is limited. The 18-cm OH maser observations of comets allow us to determine (i) the production rate of OH ($…

An RFSoC-based F-engine for ARGOS

Yunpeng Men, Ewan Barr, Amit Bansod +8

Radio interferometers provide the means to perform the wide-field-of-view (FoV), high-sensitivity observations required for modern radio surveys. As computing power per cost has de…
