The modelling work on supernova remnants made at ABBL & iTHEMS is highlighted in the latest image release from NASA's Chandra observatory
On October 17 the Chandra X-ray Observatory released an updated image of the supernova remnant known as Tycho. Supernova remnants, the aftermath of a stellar explosion, are key to understand how stars...続きを読む
Tracking down the origin of photons in gamma-ray bursts, article on RIKEN Research by Drs. S. Nagataki & D. Warren
The photons released by long gamma-ray bursts - the most powerful electromagnetic phenomena in the Universe - originate in the photosphere, the visible portion of the ‘relativistic jet’ emitted by exp...続きを読む
