2025 SKA Korea Winter Workshop

Date & Time: December 17-18 (Wed-Thu), 2025

Venue: Shilla Stay Haeundae, Busan

Rationale

The Square Kilometre Array (SKA) is now under construction, and the first Cycle 0 data are expected in the near future. Researchers in Korea have been actively contributing to the SKA through various Science Working Groups (SWGs) and recent SKA-VLBI activities. Korea will also formally join the SKA Observatory, further strengthening its role in the global SKA community. These developments mark an exciting period for the Korean SKA community, as preparations intensify toward the upcoming phases of SKA operations and data exploitation. Furthermore, in 2026 the SKA Data Challenge 4 (SDC4) will be held, and the Korean team plans to participate as a coordinated national effort. This will be an important step toward establishing Korea’s role within the global SKA community. 

We invite you to the SKA Korea Winter Workshop 2025, which will serve as a valuable opportunity for the community to gather and discuss key topics, including current and future SKA-related science research, strategies for SDC4 participation, progress on the Korean SKA data center (SKA Regional Centre) initiative, and future human resource development program. Invited and contributed talks, as well as group discussions, are planned to facilitate the exchange of ideas and to coordinate major activities for the coming year. Researchers from all areas of astronomy and related fields--not only from the field of radio astronomy--are also welcome to attend and participating in shaping the next steps for SKA science and data readiness in Korea.
