ASCA and ROSAT X-ray Spectra of IC 5063 and NGC 3998

الأصل · EN

The results of the 0.1-10 keV spectral analysis of IC 5063 (Narrow Line Radio Galaxy) and NGC 3998 (LINER) are presented. In both cases there is evidence of a FeKα emission line, but its width is poorly constrained. The highly absorbed spectrum of IC 5063 is well described by a double power law model. The X-ray luminosity of a few × 10⁴³ ergs s⁻¹ reveals a Sey 1 nucleus seen nearly edge-on, as confirmed by optical and IR studies. NGC 3998 is well fitted by a power law model (Γ 1.9) without reflection and weak absorption. The weak X-ray emission detected by ASCA and ROSAT suggests a low-luminosity AGN or an active nucleus in a low-accretion period.
