XMM-Newton observation of the low-metallicity galaxy cluster A1674 Original Research Article

We present the XMM-Newton observation of an X-ray faint cluster of galaxies A1674. Three regions of diffuse X-ray emission (A1674-NE, A1674-Center, and A1674-West) are detected from A1674. We measure the temperature and metal abundance of this diffuse emission. The diffuse X-ray emission from A1674-Center can be characterized by a thermal plasma with a characteristic temperature of image and a metal abundance of 0.07(<0.2) Z⊙. The low metal abundance of A1674-Center suggests that not enough metals are supplied from member galaxies.
