The Properties of the Absorbing and Line Emitting Material in IGR J16318-4848

Guainazzi, M.; Matt, Giorgio

We analyzed the 2003 Target of Opportunity XMM-Newton observation of IGR J16318-4848, to derive the properties of the matter responsible for the obscuration and for the emission of Fe and Ni lines. The line of sight material has a column density of about 2×10²⁴ cm^-2 but, from the Fe Kα line EW and Compton Shoulder, we argue t…
