Abstract:
Suzaku observation of the narrow line Seyfert 1 galaxy 1H0707-495
reveals a spectral drop around 7.3 keV, deepest ever observed.
We propose a new model for the spectral drop in which absorption in
corona is considered, alternative to the previously proposed
partial covering model or the relativistically blurred disk line model.
