摘要

Tycho’s supernova remnant was observed by the XIS and HXD instruments onboard the Suzaku satellite on 2006 June 26–29 for 92 ks. The spectrum up to 30 keV was well fitted with a two-component model, consisting of a power-law with a photon index of 2.7 and a thermal bremsstrahlung model with a temperature of 4.7 keV. The former component can alternatively be modeled as synchrotron emission from a p...
