| Abstract: | We present a high spatial resolution study of metal distributions in the nearby,gas-rich elliptical galaxies NGC 4374 and NGC 4636 with the Chandra ACIS archive data.We define the hardness ratio HRFeL as the ratio of the emission in 0.65-1.4keV to that in 0.3-0.6keV and 1.4-3.5keV(after the magnesium and silicon lines are excluded),and HRcont as the ratio of the emission in 1.4-3.5keV to that in 0.3-0.6keV,so that the HRFeL and HRcont maps can be used to trace the iron abundance and gas temperature distribu... |
