  • We present the results of a detailed element abundance study of hot gas in M 87, observed by XMM-Newton. We choose two radial bins, $1'{-}3'$ and $8'{-}16'$ ($8'{-}14'$ for EMOS; hereafter the central and the outer zones), where the temperature is almost constant, to carry out the detailed abundance measurements of O, Ne, Mg, Si, S, Ar, Ca, Fe and Ni using EPIC-PN (EPN) and -MOS (EMOS) data. First, we find that the element abundance pattern in the central compared to the outer zone in M 87 is… CONTINUE READING
