Long term X-ray spectroscopy of the Seyfert 1 galaxy MCG-6-30-15

GT This 100 ksec long observation of MCG63015 will be used to separate andcharacterise the components of its Xray spectrum, to study their evolution withtime and in relation to the Xray continuum and optical/UV behaviour.The galaxy shows evidence for variable absorption by ionized oxygen (whichindicates a warm absorber), for doublepeaked asymmetric profile in the FeKalpha line (attributed to the strong gravitational effects of the nuclear blackhole) and for rapid variability. We will derive physical parameters (ionizationstages, densities, gas distribution and velecities, etc.) versus time and versusXray continuum flux, and will use RGS to search for emission features(particularly OVIII Lyman alpha) from the warm absorber. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
