Intervening magnetoionic medium via Mg II absorbers
Polarimetric sightline studies isolating residual Faraday rotation of background sources to constrain galactic halo magnetization.
Research
Cosmic magnetism, radio polarimetry, and Faraday rotation — using polarised signals to infer magnetic fields and plasma.
A few simple visual building blocks that sit behind radio polarimetry and magnetoionic diagnostics. (All animations rendered in GeoGebra)
Synchrotron emission
Relativistic electrons gyrate around B-fields and emit polarised radio synchrotron emission.
Faraday rotation
Rotation of the linear polarisation angle as radiation passes through a magnetised plasma (∝ λ²).
Polarisation angle evolution
Front-on view of the rotating polarisation vector — the observable tracked across frequency.
Spatial RM statistics of resolved radio lobes
Resolution-aware spatial analysis with robust error propagation to support survey-ready validation for next-generation wide-field polarimetry.
Gravitational lensing: PKS 1830−211
Geometric modeling to separate intrinsic source physics from lens magnification, including work enabling the ALMA detection of the third image.
