资源简介:

We propose a ToO observation of the highly variable Seyfert galaxy NGC 2992 withXMMNewton for 250 ks. The pointing will be triggered by SwiftXRT to catch thesource during its bright flux state. Even though the source has been extensivelyobserved by all major Xray satellites, its high flux state is still poorlystudied. The time behavior of the iron line is very interesting, suggesting thepresence of a relativistic component which becomes more extreme at high fluxlevels. In addition, an outflow component has been found in the recent NuSTARspectrum and confirmed by a reanalysis of the 2003 XMM observation. We aim atinvestigating the spectral evolution of the accretion disk features in the highstate, on a time scale of a few hours. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
