[Press Release] Understanding the last 1/100 seconds before falling into a black hole
Shinya Yamada has found that an accreting gas falling into a black hole is heated instantly within 1/100 seconds, by applying a shot analysis technique into the Suzaku HXD data taken from a famous black hole binary Cygnus X-1. Further improvements on this study is expected from the next to Suzaku satellite, ASTRO-H, and the first X-ray polarimetry […]
Katsuda's paper on the Cygnus Loop has been accpected for publication in The Astrophysical Journal Letters.
Dr. Katsuda and a team of scientist have discovered a pulsar wind nebula candidate in the Cygnus Loop supernova remnant, based on X-ray observations with Suzaku and XMM-Newton. While the origin of the Cygnus Loop has been believed to be a core-collapse of a massive star, no neutron star associated with the remnant has been […]
