The Compton shoulder of the Fe Kalpha fluorescent emission line in active galactic nuclei
The Compton shoulder the Fe Kalpha fluorescent emission line
2011/1/11
We present new, high signal-to-noise ratio results from a Monte Carlo study of the properties of the Compton shoulder of the Fe Kalpha emission line in the toroidal X-ray reprocessor model of Murphy &...
Fe-K line probing of material around the AGN central engine with Suzaku
galaxies active — galaxies Seyfert — X-rays galaxies
2010/11/11
We systematically analyzed the high-quality Suzaku data of 88 Seyfert galax-ies, about 31% of which are Compton-thick AGNs. We obtained a clear relation between the absorption column density and the e...
Monte Carlo simulations of the Nickel K$\alpha$ fluorescent emission line in a toroidal geometry
galaxies active - line formation - radiation mechanism general - scattering - X-rays general
2010/11/12
We present new results from Monte Carlo calculations of the flux and equivalent width(EW) of the Ni K fluorescent emission line in the toroidal X-ray reprocessor model of Murphy & Yaqoob (2009, MNRAS...
Evidence of Decay of Flux Ratio of Fe to Fe–Ni Line Features with Electron Temperature in Solar Flares
Sun flares corona—X-rays
2010/9/15
We report observational evidence of the decay of the flux ratio of Fe to Fe–Ni line features as a function of plasma electron temperature in solar flares in comparison to that theoretically predicted ...
