Detection of Cyclotron Absorption in the Radio Emission of GPM 1839-10
Yunpeng Men, Ewan Barr, Yuanhong Qu +8
GPM 1839-10 is an intriguing long-period radio transient (LPT), distinguished by its activity spanning at least three decades and its highly unusual emission characteristics. These…
Localisation and host galaxy identification of new Fast Radio Bursts with MeerKAT
Inés Pastor-Marazuela, Alexa C. Gordon, Ben Stappers +18
Accurately localising fast radio bursts (FRBs) is essential for understanding their birth environments and for their use as cosmological probes. Recent advances in radio interferom…
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 ($…
A highly magnetized long-period radio transient exhibiting unusual emission features
Yunpeng Men, Sam McSweeney, Natasha Hurley-Walker +2
Long-period radio transients are a new class of astrophysical objects that exhibit periodic radio emission on timescales of tens of minutes. Their true nature remains unknown; poss…
