| Abstract: |
High-resolution X-ray observations of the prototype starburst galaxy M82 obtained with the Advanced CCD (charge coupled device) Imaging Spectrometer on board the Chandra X-Ray Observatory provide a detailed view of hot plasma and energetic processes. Plasma with temperature ~40 MK fills the inner 1 kpc, far hotter than the 1--2 MK interstellar medium component in the Milky Way Galaxy. Produced by many supernova explosions, this central region is overpressurized and drives M82's prominent galactic wind into the intergalactic medium. We also resolved about twenty compact X-ray sources, many of which could be high-mass X-ray binary star systems containing black holes. |
