Full Mueller imaging: direction dependent corrections in polarimetric radio imaging
… acceleration, star formation, or the launch of radio galaxy jets, pulsars, etc. One key fundamental process that allows us to detect and characterize cosmic magnetic fields with radio astronomy is the polarization of synchrotron radiation. Synchrotron radiation is intrinsically polarized …

2-D radio imaging of equatorial ionospheric plasma depletions with the C/NOFS satellite: algorithms and results
… impacts. A promising technique for direct imaging of these irregularities is based on a combination of satellite-borne and ground instruments, together with tomographic inversion techniques, to obtain multi-dimensional images of the ionospheric electron density. However, the inverse problem …

Visualising the Aurora: Embodied and Instrumental Sensing throughout the International Polar and Geophysical Years (1880-1960)
… of the phenomenon, from hand-drawings to radio echoes, while paying heed to what was occluded from portrayals, the imaginative and aesthetic considerations involved in rendering the aurora and the epistemological problems of capturing a transient, unpredictable and intangible atmospheric …

The development of new methods for high resolution radio astronomy imaging
… development of new methods for high resolution radio astronomy imaging in both of these areas. An implementation of the Maximum Entropy Method (MEM) suitable for multi-wavelength VLBI polarisation observations is presented and the advantage in resolution it possesses over the CLEAN algorithm is …
