X - ray continuum variability of MCG – 6 - 30 - 15
This paper presents a comprehensive examination of the X-ray continuum variability of the bright Seyfert 1 galaxy MCG–6-30-15. The source clearly shows the strong, linear correlation between rms variability amplitude and flux first seen in Galactic X-ray binaries. The high frequency power spectral density (PSD) of MCG–6-30-15 is examined in detail using a Monte Carlo fitting procedure and is fo...
متن کاملIonized Disc Models of MCG – 6 - 30 - 15
Ionized reflection is one of the possible mechanisms proposed to explain the small short-timescale variability of the MCG–6-30-15 Fe Kα line. In this contribution, we fit the Ross & Fabian ionized reflection models to the 325 ks XMM-Newton observation of MCG–6-30-15. It is found that the spectrum above 2.5 keV can be fitted with a combination of an ionized reflector from 5 r g and a neutral rep...
متن کاملRelativistic ionized accretion disc models of MCG–6-30-15
We present results from fitting ionized disc models to three long ASCA observations of the Seyfert 1 galaxy MCG–6-30-15. All three datasets are well fit by a model consisting of ionized reflection from the inner region of the accretion disc (with twice solar Fe abundance) and a separate diskline component from farther out on the the disc. The diskline is required to fit the height of the observ...
متن کاملImplications of the X-Ray Variability for the Mass of MCG -6-30-15.
The bright Seyfert 1 galaxy MCG -6-30-15 shows large variability on a variety of timescales. We study the less, similar3 day timescale variability using a set of simultaneous archival observations that were obtained from the Rossi X-Ray Timing Explorer (RXTE) and the Advanced Satellite for Cosmology and Astrophysics (ASCA). The RXTE observations span nearly 106 s and indicate that the X-ray Fou...
متن کاملAn absorption origin for the X - ray spectral variability of MCG – 6 - 30 - 15
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
