Radio astronomers bypass disturbing Earth's atmosphere with new calibration technique
Mon 6 May 2024- An international team of researchers led by astronomers from Leiden University (the Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Earth's ionosphere. They used the new method to study plasmas from ancient black hole bursts. Potentially, the technique might be useful for finding exoplanets that orbit small stars. The researchers report their technique in the journal Nature Astronomy.
