China's FAST telescope releases largest neutral hydrogen catalog, surpassing US survey

By PulseAugur Editorial · [1 sources] ·

China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) has released the world's largest catalog of neutral hydrogen beyond the Milky Way. This new dataset, containing over 156,000 extragalactic sources, significantly surpasses the data from the now-defunct Arecibo Radio Telescope in Puerto Rico. The FAST All-Sky H I Survey (FASHI) aims to provide astronomers globally with a comprehensive resource for studying the formation and evolution of stars and galaxies, serving as a bridge to future projects like the Square Kilometre Array.

    China’s FAST telescope maps neutral hydrogen, the cosmic gas for making stars

    China’s FAST telescope has compiled the world’s largest catalogue of neutral hydrogen beyond the Milky Way, replacing a long-dominant US survey as the main reference for mapping the gas that fuels the formation of stars and galaxies. The FAST All-Sky H I Survey (FASHI), conducted…
