Eliciting an energetic secret from the Crab Nebula

The Crab Nebula is the remnant of a supernova in our Galaxy which was observed almost 1000 years ago. Although it corresponds to one of the most studied celestial objects, its extension in very high energy gamma-rays has up to now remained unknown. The international team of scientists of the H.E.S.S. telescopes now finally succeeded … Read more

Astrophysicists link brightening of pulsar wind nebula to pulsar spin-down rate transition

Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU Fangjun at the Institute of High Energy Physics of the Chinese Academy of Sciences, provides … Read more
