The Tianlai experimental array, China's first dark energy radio detection project, has been successfully certified as a SKA Pathfinder by the Square Kilometre Array (SKA) organization, an intergovernmental organization with 10 international member states, the Global Times learned from the National Astronomical Observatories of the Chinese Academy of Sciences on Monday. The recognition is expected to offer new opportunities for scientific exploration and test innovative detection technologies for the SKA.According to astronomical observations, about 70 percent of the universe is composed of mysterious dark energy, which is causing the accelerated expansion of the universe.As a SKA Pathfinder project, the Tianlai array can test technologies for detecting neutral hydrogen, allowing for the extraction of faint 21-centimeter hydrogen signals. "These techniques can be applied to the SKA project. Through practical observations and data analyses, we can identify real-world issues that theoretical analyses alone cannot fully address," said Chen Xuelei, chief scientist of the Tianlai project and researcher at the National Astronomical Observatories.Robert Braun, the science director of the SKA, noted that the Tianlai project will pave the way for the SKA radio observatory. Although the organization is in its initial operational phase, the existing radio antennas and experimental projects will continue to provide insights for scientific plans and research foundations, Braun said.In addition, these technologies can also be applied to future large-scale astronomical telescope projects, the Global Times learned from the National Astronomical Observatories.The SKA is a next-generation giant radio telescope array currently under construction, representing an intergovernmental collaboration involving 10 countries, including China, South Africa, the UK and Australia. The SKA Pathfinder project includes various large scientific instruments from around the world related to SKA science and technology.This article was originally published by Global Times.

Сhina's Dark Energy Radio Project Gets SKA Pathfinder Certification
China's Tianlai experimental array, the country's first dark energy radio detection project, has been certified as a SKA Pathfinder by the Square Kilometre Array organization, opening up new avenues for scientific exploration and testing innovative detection technologies.
The Tianlai experimental array, China's first dark energy radio detection project, has been successfully certified as a SKA Pathfinder by the Square Kilometre Array (SKA) organization, an intergovernmental organization with 10 international member states, the Global Times learned from the National Astronomical Observatories of the Chinese Academy of Sciences on Monday.
The recognition is expected to offer new opportunities for scientific exploration and test innovative detection technologies for the SKA.
The project is located at an observation station in Hami, Northwest China's Xinjiang Uygur Autonomous Region. It primarily conducts neutral hydrogen surveys, which is used to study the large-scale structure of the universe, dark energy, and other cutting-edge cosmological topics.
According to astronomical observations, about 70 percent of the universe is composed of mysterious dark energy, which is causing the accelerated expansion of the universe.
The array features both cylindrical and dish-shaped antennas. The cylindrical array consists of three paraboloid reflector antennas, each equipped with 96 feeds, while the dish array includes 16 six-meter diameter parabolic antennas.
As a SKA Pathfinder project, the Tianlai array can test technologies for detecting neutral hydrogen, allowing for the extraction of faint 21-centimeter hydrogen signals. "These techniques can be applied to the SKA project. Through practical observations and data analyses, we can identify real-world issues that theoretical analyses alone cannot fully address," said Chen Xuelei, chief scientist of the Tianlai project and researcher at the National Astronomical Observatories.
