Suzaku observations of X-ray excess emission in the cluster of galaxies A3112

Understand

We analysed the Suzaku XIS1 data of the A3112 cluster of galaxies in order to examine the X-ray excess emission in this cluster reported earlier with the XMM-Newton and Chandra satellites.

• The best-fit temperature of the intracluster gas depends strongly on the choice of the energy band used for the spectral analysis.
• This proves the existence of excess emission component in addition to the single-temperature MEKAL in A3112.
• We showed that this effect is not an artifact due to uncertainties of the background modeling, instrument calibration or the amount of Galactic absorption.
