Chinese astronomers discover energetic pulsar wind nebula

The LHAASO instrument has spotted a natural particle accelerator that should not exist. The conventional theories of particle acceleration in pulsar wind nebulae are challenged by the discovery.

New Delhi: The Large High Altitude Air Shower Observatory (LHAASO) in China has detected energetic gamma-ray emission from a pulsar wind nebula, powered by a pulsar designated as PSR J1849-001 in the constellation of Aquila, which challenges the conventional theories on particle acceleration in Pulsar Wind Nebulae. The discovery is important because the calculated particle acceleration efficiency of the celestial structure approaches or even exceeds the........
