Abstract

The Square Kilometre Array (SKA) promises groundbreaking advances in key scientific areas, including ultra-sensitive continuum imaging and probing the cosmos through redshifted spectral lines from the epochs of cosmic dawn and reionization. However, achieving these ambitious goals requires overcoming significant challenges, particularly at low frequencies. These include ionospheric distortions, wide fields of view, complex antenna layouts, and the massive data volumes generated—all of which make calibration and imaging exceptionally difficult.

While precursor instruments have demonstrated steady progress and highlighted SKA’s immense scientific potential, the complexity of the SKA's mission demands innovative, independent approaches to deliver robust results. This unique landscape presents unparalleled opportunities for developing novel methods to address calibration and imaging challenges at scale.

In this talk, I will showcase promising advancements in tools designed for calibration and imaging. These methods offer a glimpse into how we can tackle SKA's challenges and harness its full potential, paving the way for transformative discoveries in astronomy.
