Iron and nickel line properties in the X-ray-reflecting region of the Circinus galaxy
We discuss the iron and nickel properties in the nuclear X-ray reflecting region of the Circinus Galaxy, studied with XMM-Newton. The main results are: a) from the depth of the Fe Kalpha edge, a value of A_Fe=1.7 in number with respect to the cosmic value (as for Anders & Grevesse …
