ABSTRACT
Managing the growing volume of data being output by radio telescopes is a significant challenge faced by radio astronomers today. This challenge will only be further compounded with future telescopes such as the Square Kilometre Array (SKA), which will be the world's largest radio telescope when completed and produce data at unprecedented rates. This paper introduces the CyberSKA collaborative portal which is aimed at addressing the current and future needs of data-intensive radio astronomy. A wide variety of tools and services that have been developed and integrated with the CyberSKA portal, including a distributed data management system, a data access tool, remote visualization tools and a third party application interface are described. Current international usage of CyberSKA focusing on several different SKA Pathfinder survey projects and how they make use of the portal are also highlighted.

As astronomical data is getting larger and larger, information platforms fostering collaboration and supporting information management are a priority for researchers around the world. CyberSKA is an online platform that serves the astronomical community in understanding and evaluating information captured by the world's largest telescopes. This paper succinctly and generally presents the overall architecture of CyberSKA, offering a good overview of the platform's functionalities and features. The data increase problem is well correlated with other challenges that CyberSKA addresses. Additionally, the main aims of the project are well described and refer to the access and sharing of data and the collaboration of targeted domain scientists and radio astronomers. Proving its universal role for radio data analysis, the authors emphasize the different layers of the portal: collaboration on the one hand, and data management, data processing, and visualization services on the other. Furthermore, it is interesting to note the current progress of CyberSKA with actual functions and implementations, as well as future plans for development. Another key contribution of the paper is its two case studies on imaging and pulsar surveys, which explain how different groups collaborate and share information in CyberSKA.
