"Cosmic Whistle" Packs a Surprisingly Energetic Punch
Cosmic Whistle Surprisingly Energetic Punch
2016/11/29
Penn State University astronomers have discovered that the mysterious "cosmic whistles" known as fast radio bursts can pack a serious punch, in some cases releasing a billion times more energy in gamm...
We report the discovery of a prominent non-thermal X-ray feature located near the Galactic centre that we identify as an energetic pulsar wind nebula. This feature, G359.95-0.04, lies 1-lyr north of S...
