Accurate Determination of Chemical Abundances near a Supermassive Black Hole
The XRISM collaboration
The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…

The Problem of the High Iron Abundance in Accretion Disks around Black Holes
J. A. García, T. R. Kallman, M. Bautista +4
In most accreting black-hole systems the copious X-rays commonly observed from the inner-most regions are accompanied by a reflection spectrum. The latter is the signature of energ…

Nitrogen K-shell photoabsorption
J. Garcia, T. R. Kallman, M. Witthoeft +6
Reliable atomic data have been computed for the spectral modeling of the nitrogen K lines, which may lead to useful astrophysical diagnostics. Data sets comprise valence and K-vaca…
