ABSTRACT
PG 1244+026 is a `simple' Narrow Line Seyfert 1 galaxy, showing neither strong reflection features at iron, nor dramatic spectral-variability. Spectral-timing analysis strongly supports the soft X-ray excess being an additional component rather than ionised reflection. Yet the current data show lag-frequency and lag-energy spectra that are similar to those from sources apparently dominated by ionised reflection. We propose a 600 ks observation (5 full orbits) of this source to better constrain these higher order spectra, and interpret them in light of the known spectral components. This will i) revolutionise our understanding of the reverberation signal in a simple spectrum source; ii) allow for the first time two independent spin methods to be tested in the same AGN.

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
