The 21-cm signal from the Epoch of Reionization (EoR) is a powerful probe of the evolution of the Universe. However, accurate measurements of the EoR signal from radio interferometric observations are sensitive to efficient foreground removal, mitigating radio-frequency interference and accounting for instrumental systematics. We investigate the impact of the variations in the point spread...

32. RRIvis: A GPU-Accelerated, Full-Polarization Visibility Simulator for Radio Interferometry

Precision modelling of instrumental effects is critical for radio interferometry, particularly for 21cm cosmology and Epoch of Reionisation (EoR) experiments, where detecting faint signals requires rigorous foreground subtraction. We present RRIvis, a new open-source Python package designed to address the need for accuracy and flexibility in simulating interferometric visibilities. Built on...
