Suzaku observations of Fe K α line in some Magnetic Cataclysmic Variables

Eze, R. N. C.

We resolved the 6.4 keV, 6.7 keV and 7.0 keV Fe K α lines in 19 Magnetic Cataclysmic Variables (mCVs) observed with the Suzaku satellite. The 6.7 keV and 7.0 keV emission lines are typically created by collisional excitation in the vicinity of the white dwarf arising from the shock front. The 6.4 keV iron emission line in contrast is formed in equ…

On the origin of the iron fluorescent line emission from the Galactic Ridge

Eze, R. N. C.

The Galactic Ridge X-ray Emission (GRXE) spectrum has strong iron emission lines at 6.4, 6.7, and 7.0 keV, each corresponding to the neutral (or low-ionized), He-like, and H-like iron ions. The 6.4 keV fluorescence line is due to irradiation of neutral (or low ionized) material (iron) by hard X-ray sources, indicating uniform presence of the cold …

On the origin of the Fe Kα emission line from intermediate polar EX Hyrae

Eze, R. N. C.; Esaenwi, S.

We present spectral analysis of intermediate polar EX Hya observed with Suzaku satellite on 18-07-2007 for 91 kilo seconds (ks). We model the spectrum with an absorbed thermal bremsstrahlung and three Gaussian lines for the Fe Kα line complex. We resolved the 6.4, 6.7, and 7.0 keV lines, each corresponding to the neutral (or low-ionized), He-like,…

Preliminary results of the spectral analysis of Suzaku data of SW Ursae Majoris and BZ Ursae Majoris

Gök, F.; İkis Gün, G.; Karagül, A.

Herein, we present the preliminary results of the spectral analysis of the Suzaku data of SW Ursae Majoris (SW UMa) and BZ Ursae Majoris (BZ UMa) which were obtained in their quiescent states. The aim of this study was to analyse 0.5-6.0 keV energy range X-ray photons of the Suzaku satellite and to determine their emission mechanisms and the areas…
