Discovery of a radio-flaring M dwarf in a commensal transient search of the LADUMA field
Moses Mlangeni, Patrick A. Woudt, Paul J. Groot +11
We report the discovery and characterisation of MKT J032848.4-271904.6, a new radio transient identified in the LADUMA field using SARAO Science Data Processor (SDP) UHF-band image…
The Homogeneous MeerKAT and Swift/XRT X-ray Binary Radio:X-ray Plane
Justine Crook-Mansour, Rob Fender, Andrew Hughes +22
During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the c…
Large-scale radio bubbles around the black hole transient V4641 Sgr
Noa Grollimund, Stéphane Corbel, Rob Fender +7
Black holes (BHs) in microquasars can launch powerful relativistic jets that have the capacity to travel up to several parsecs from the compact object and interact with the interst…
Detection of spin-modulated circular polarisation and radial velocity variations in the long period Intermediate Polar 1RXS J080114.6-462324
V. Moloi, S. B. Potter, Z. N. Khangale +3
We present a comprehensive photometric, spectroscopic, and polarimetric study of the intermediate polar (IP) 1RXS J080114.6-462324, using observations from the South African Astron…
MeerKAT discovery of 164 compact radio rings toward the Galactic Plane
C. Bordiu, F. Bufano, G. Umana +14
We report the discovery of 164 compact (radius < 1 arcmin) radio rings using MeerKAT 1.3 GHz data from the SARAO MeerKAT Galactic Plane Survey (l=2-60deg, 252-358deg, |b|<1.5deg) a…
Relativistic precessing jets powered by an accreting neutron star
F. J. Cowie, R. P. Fender, I. Heywood +9
Precessing relativistic jets launched by compact objects are rarely directly measured, and present an invaluable opportunity to better understand many features of astrophysical jet…
