Permanent Hawking radiation was measured in the acoustic black hole at the Technion

In an article published in the journal Nature Physics in early 2021, the research group showed that permanent (stationary) Hawking radiation was indeed emitted from the acoustic black hole. They measured 97,000 repetitions of the experiment which is equivalent to 124
