Astronomers discover ultra-fast radio bursts in archived data

An international team of researchers has discovered radio pulses that last only millionths of a second. With this, the team – led by Dutch Ph.D candidate Mark Snelders (ASTRON and University of Amsterdam) – have proven that previously discovered fast radio bursts (FRBs) can last even shorter than a thousandth of a second, giving life to the term ‘ultra-fast radio bursts’.

Where FRBs are possibly caused by magnetic neutrons stars, the origin of ultra-fast radio bursts is still unknown. Snelders and his team published about their results in Nature Astronomy.
