[50.10] Re-evaluation of the Temporal behavior of the Gravitationally Redshifted Fe K alpha line in MCG-6-30-15 and with Archival Ginga Data

R. Sivron, T. Franklin (Bucknell University)

We have re-analized ~200 ks of old archival X-ray data from the Ginga satellite observations of the Seyfert 1 galaxy MCG-6-30-15. We have re-evaluated the results of the 1987, 1989, 1990 and 1991 observations in the light of the discovery of a variable red shifted Fe line in the Asca 1994 (Iwasawa et. al. 1996) and RXTE 1997 data (Lee et. al. 1999), believed to be gravitationally redshifted (Tanaka et.al. 1995). Once a "core" non-redshifted line, similar to that found in the later observations,is added to the models the variable gravitationally redshifted line is statistically significant. We also find interesting temporal correlation between the continuum spectrum, the compton reflection hump and the red shifted line on time scales of hours and days. We interpret these correlations in the context of linear and non - linear models of AGN central engines.
