Abstract
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.
Papers
Authors marked in red are (co-)investigators in the proposal
Classification of papers are:
- CLASS 1:
papers that present specific XMM-Newton observations
- CLASS 2:
papers that refer to published XMM-Newton results with
complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3:
further deliveries which resulted from the program and which are made
available to the community (e.g. source catalogues, processed images or
spectra in public data base)
- CLASS 4:
comments and suggestions from PI
