X-ray warm absorber variability of the Seyfert Galaxy Arakelian 564
The aim of this paper is to study the variability of the warm absorber "clouds of ionised gas within AGN", for the Seyfert 1 galaxies Arakelian 564. The X-ray spectra for four XMM-Newton observations of this object are analysed in EPIC and RGS instruments. These four observations covered a...

| description | The aim of this paper is to study the variability of the warm absorber "clouds of ionised gas within AGN", for the Seyfert 1 galaxies Arakelian 564. The X-ray spectra for four XMM-Newton observations of this object are analysed in EPIC and RGS instruments. These four observations covered a period of eleven years. There are some changes in the ionisation parameter (\( \xi \)) of the absorbing matter from one observation to another( \(\log\xi =0.889 \pm 3.11 \times 10^{-2}\) for year 2000 observation and \(0.437 \pm 7.60 \times 10^{-2}\) for year 2001 ). Also the X-ray soft excess is studied for the four observation by using two blackbody parameters in EPIC spectra ( the first black-body temperature is \(\sim \) \(0.129 \pm 2.04 \times 10^{-3}\) Kev and the second is \(\sim 1.74 \pm 7.6 \times {10^{-2}}\) Kev) and one black body parameter in RGS spectra. |
