An RXTE Observation of the Seyfert 1 Galaxy MCG − 6 - 30 - 15 : X - ray Reflection and the Iron Abundance
نویسندگان
چکیده
We report on a 50 ks observation of the bright Seyfert 1 galaxy MCG−6-30-15 with the Rossi X-ray Timing Explorer. The data clearly show the broad fluorescent iron line (equivalent width ∼ 250 eV), and the Compton reflection continuum at higher energies. A comparison of the iron line and the reflection continuum has enabled us to constrain reflective fraction and the elemental abundances in the accretion disk. Temporal studies provide evidence that spectral variability is due to changes in both the amount of reflection seen and the properties of the primary X-ray source itself.

The X-ray variability of the Seyfert 1 galaxy MCG 6-30-15 from long ASCA and RXTE observations
We present an analysis of the long Rossi X-ray Timing Explorer (RXTE ) observation of the Seyfert 1 galaxy MCG 6-30-15, taken in July 1997. We have earlier used the data to place constraints for the first time on the iron abundance reflection fraction relationship, and now expand the analysis to investigate in detail the spectral X-ray variability of the object. Our results show that the behavi...
متن کاملFirst Constraints on Iron Abundance versus Reflection Fraction from the Seyfert 1 Galaxy MCG – 6 - 30 - 15
We report on a joint ASCA and RXTE observation spanning an 400 ks time interval of the bright Seyfert 1 galaxy MCG–6-30-15. The data clearly confirm the presence of a broad skewed iron line (WK 266 eV) and Compton reflection continuum at higher energies reported in our previous paper. We also investigate whether the gravitational and Doppler effects that affect the iron line may also be manifes...
متن کاملObservation of NGC 6300 : a new bright Compton reflection Dominated Seyfert 2 Galaxy
Scanning and pointed RXTE observations of the nearby Seyfert 2 galaxy NGC 6300 reveal that it is a source of hard X-ray continuum and large equivalent width Fe Kα emission. These properties are characteristic of Compton-reflection dominated Seyfert 2 galaxies. The continuum can be modeled as Compton-reflection; subsolar iron abundance is required and a high inclination preferred. However, the p...
متن کاملDetecting Compton Reflection and a Broad Iron Line in MCG−5-23-16 with RXTE
We report the detection with the Rossi X-ray Timing Explorer of a Compton reflection signature in the Seyfert galaxy MCG−5-23-16. RXTE also resolves the Fe Kα fluorescence line with FWHM ∼ 48,000 km s. This measurement provides the first independent confirmation of ASCA detections in Seyfert galaxies of broad Fe Kα lines that are thought to be the signature of emission from the inner regions of...

Context. The Seyfert I galaxy MCG−6-30-15 shows one of the best examples of a broad “red wing” of emission in its X-ray spectrum at energies 2 < E < 6.4 keV, commonly interpreted as being caused by relativistically-blurred reflection close to the event horizon of
