Einstein Probe detects strange cosmic explosion – Media INAF

Less than three months after its launch, the Einstein Probe telescope has discovered a burst of low-energy X-rays that could lead scientists to reconsider how gamma-ray bursts are emitted. The explosion in question lasted more than 17 minutes – the longest ever observed – and, strangely, only after six minutes did the gamma-ray burst appear. The details are in Nature Astronomy where we find among the signatories of the article our researcher Giancarlo Ghirlanda and ApJ Letters – Read the full story on Media INAF

The Einstein Probe detected the faint X-ray signal of the transient EP240315a long before its gamma-ray counterpart. This demonstrates the high sensitivity of its optics. Follow-up observations showed that the burst came from about 12.5 billion light-years away, starting its cosmic journey towards us when the universe was just 10 percent of its current age.
