This work presents a framework for joint calibration and map-making using Gibbs sampling. Instead of conditioning on a fixed noise level, our data model employs multiplicative noise as a direct application of the radiometer equation, accurately capturing the coupling between noise level and system temperature. To enable unbiased and fast estimation of gain and system temperature, we develop an...
The Square Kilometer Array (SKA-Mid) will map the post-reionization Universe, using the 21cm line emitted by the neutral Hydrogen (HI) with accuracy and detail that was never possible. The SKA-Mid will first make the statistical detection of the 21cm signal via power spectrum measurements, and the inference of astrophysics of the galaxies and Cosmology will follow with these detections. The...
