This conference talk explores the challenges of recovering redshifted 21-cm power spectrum with a focus on residual gain effects, presented by Saikat Gayen at the International Centre for Theoretical Sciences. Part of the "Radio Cosmology and Continuum Observations in the SKA Era: A Synergic View" program, the 16-minute presentation contributes to discussions about radio cosmology research in preparation for the Square Kilometre Array (SKA) telescope. Learn about cutting-edge techniques for addressing calibration challenges that affect 21-cm signal detection, which is crucial for studying cosmic evolution. The talk is part of a broader two-week program bringing together experts in radio cosmology and continuum science, designed to foster collaboration and train the next generation of researchers ahead of the SKA's 2027 operational launch.
