Michael Smith, ESAC


Calibration Source (I)

CalClosed line width monitoring: First single events, complete FOV.

Al-K: 9.4 ± 0.7 x 10-4 eV/Rev

Mn-K: 3.2 ± 0.1 x 10-3 eV/Rev

Calibration Source (II)

CalClosed line width monitoring: First single events, RAWY > 180.

Al-K: 1.5 ± 0.2 x 10-3 eV/Rev

Mn-K: 5.9 ± 0.2 x 10-3 eV/Rev

Astrophysical Sources
From previous results: Analysis of line width trends at Fe-K energies of SNR N132D and Eta Carinae (F. Haberl, 2010) do not confirm the time dependence of the energy resolution seen in the calibration source. E.g., even comparing over a base line of ~1000 revolutions the measured line widths were statistically consistent.

Now: analysis of Fe-K emission line widths in obscured AGN. X-ray spectrum dominated by reflection components. Fe-K emission assumed to be essentially neutral in origin, and intrinsically narrow. Sample consisting of 20 observation of 12 sources. Sources are either point-like or compact extended, located at the bore sight. Spectra created w/ single + double events.
