Scientific paper

XMM observations have shown that relativistically-broadened iron-K lines and reflection features are common in the spectra of Seyfert 1 galaxies. These offer a means to understand the inner working of accreting black holes, which are the most powerful persistent sources in the Universe. Our XMM observation of the NLS1 galaxy 1H0707-495 shows broad iron-L and K emission which confirm the reflection model. The combination of high soft X-ray count rate in the iron-L band and long exposure has enabled us to measure X-ray reverberation of 30s for the first time. Here we propose long observations of a similar exceptional object, IRAS 13224-3809, which shows extreme spectral features and variability. Long exposures on such objects enables us to take accreting black hole studies to the next level.
