| On why the Iron K-shell absorption in AGN is not a signature of the local Warm/Hot Intergalactic Medium (2008) | |||||||||
Abstract | |||||||||
| We present a comparison between the 2001 XMM-Newton and 2005 Suzaku observations of the quasar, PG1211+143 at z=0.0809. Variability is observed in the 7 keV iron K-shell absorption line (at 7.6 keV in the quasar frame), which is significantly weaker in 2005 than during the 2001 XMM-Newton observation. From a recombination timescale of 0.004 particles/cm3, while the absorber column is 5e22. Comment: accepted for publication in MNRAS LETTERS. 5 pages, 4 figures | |||||||||
