The magnetic field strength of a methane dwarf measured from its radio spectral cutoff
Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1
Brown dwarfs and gas-giant planets are expected to emit coherent radio emission via the electron cyclotron maser instability (ECMI) mechanism powered by non-thermal electrons in th…
Unusual periodic modulation in the radio emission of the methane dwarf binary WISEP J101905.63+652954.2
Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1
Brown dwarfs display Jupiter-like auroral phenomena, such as rotationally modulated electron cyclotron maser radio emission. Radio observations of cyclotron maser emission can be u…
Radio emission as a stellar activity indicator
Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1
Radio observations of stars trace the plasma conditions and magnetic field properties of stellar magnetospheres and coronae. Depending on the plasma conditions at the emitter site,…
V-LoTSS: The Circularly-Polarised LOFAR Two-metre Sky Survey
J. R. Callingham, T. W. Shimwell, H. K. Vedantham +44
We present the detection of 68 sources from the most sensitive radio survey in circular polarisation conducted to date. We use the second data release of the 144 MHz LOFAR Two-metr…
A tomographic spherical mass map emulator of the KiDS-1000 survey using conditional generative adversarial networks
Timothy Wing Hei Yiu, Janis Fluri, Tomasz Kacprzak
Large sets of matter density simulations are becoming increasingly important in large-scale structure cosmology. Matter power spectra emulators, such as the Euclid Emulator and Cos…
