SKA Non-imaging Processing Software 2025 - 2027

The Square Kilometre Array (SKA) will generate 1500 simultaneous beams from its MID telescope and 500 from its LOW telescope to scan the entire visible sky for pulsars and fast radio bursts. Each beam acts like a separate radio eye, and software must sift through every one for the faint, periodic signals of spinning neutron stars. Pulsars are nature’s most precise cosmic clocks, but only a fraction of those in our galaxy have been found. Current telescopes miss most of them because they cannot cover enough sky quickly enough. The SKA’s non-imaging processing software solves this by combining signals from hundreds of dishes or dipoles into many narrow beams at once, then searching each beam independently for pulsar candidates and rejecting false positives. This is fundamental science. Success means cataloguing thousands of new pulsars, which will test theories of gravity, map the interstellar medium, and improve the timing arrays used to detect gravitational waves. There is no immediate practical application, but pulsar discoveries have historically enabled tests of general relativity and provided the first exoplanet detection. Deeper knowledge of neutron stars could one day inform extreme-matter physics or navigation systems that rely on cosmic timing.
