VLBI with SKAMPI, the SKA-Mid MPIfR dish demonstrator
Jompoj Wongphechauxsorn, Niclas Alexander Esser, Tobias Winchen +13
The SKA-MPIfR telescope (SKAMPI) is a prototype SKA-Mid antenna located at the SKA site in the Karoo Desert, South Africa. It is funded by the Max Planck Society, through the Max P…
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…
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…
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 ($…
First search for axion dark matter with a Madmax prototype
B. Ary dos Santos Garcia, D. Bergermann, A. Caldwell +34
This paper presents the first search for dark matter axions with mass in the ranges 76.56 to 76.82 eV and 79.31 to 79.53 eV using a prototype setup for the MAgnetized Disk…
