Scientific paper

The warm absorber of the low-luminosity Seyfert NGC 3227 is characterized by low levels of ionization, making it relatively unique among Seyferts. A high-quality grating spectrum, taken when the source is not in an obscured state, is needed for further detailed study of the warm absorber. We propose a 110 ksec XMM-Newton observation to obtain RGS and EPIC spectra, probe the warm and neutral absorber properties, search for expected signatures of dust embedded in the warm absorber, and search for flux-dependent spectral changes. We will also characterize energy-dependent timing properties to fully explore Seyfert/X-ray Binary analogies, and search for correlated X-ray/UV flux variability to test reprocessing models.
