Unbiased correction relations for galaxy cluster properties derived from Chandra and XMM-Newton.

Abstract (from CDS):

We use a sample of 62 clusters of galaxies to investigate the discrepancies between the gas temperature and total mass within r500 from XMM-Newton and Chandra data. Comparisons of the properties show that (1) both the de-projected and projected temperatures determined by Chandra are higher than those of XMM-Newton and there is a good linear relationship for the de-projected temperatures: TChandra= 1.25xTXMM-0.13. (2) The Chandra mass is much higher than the XMM-Newton mass with a bias of 0.15 and our mass relation is log10MChandra= 1.02xlog10MXMM+0.15. To explore the reasons for the discrepancy in mass, we recalculate the Chandra mass (expressed as MChmo/d) by modifying its temperature with the de-projected temperature relation. The results show that MChmo/d is closer to the XMM-Newton mass with the bias reducing to 0.02. Moreover, MChmo/d are corrected with the r500measured by XMM-Newton and the intrinsic scatter is significantly improved with the value reducing from 0.20 to 0.12. These mean that the temperature bias may be the main factor causing the mass bias. Finally, we find that MChmo/d is consistent with the corresponding XMM-Newton mass derived directly from our mass relation at a given Chandra mass. Thus, the de-projected temperature and mass relations can provide unbiased corrections for galaxy cluster properties derived from Chandra and XMM-Newton.
