Photoionization modeling of oxygen K absorption in the interstellar medium:the Chandra grating spectra of XTE J1817-330
E. Gatuzz, J. García, C. Mendoza +6
We present detailed analyses of oxygen K absorption in the interstellar medium (ISM) using four high-resolution Chandra spectra towards the X-ray low-mass binary XTE J1817-330. The…
K-shell photoionization of Nickel ions using R-matrix
M. C. Witthoeft, M. A. Bautista, J. Garcia +4
We present R-matrix calculations of photoabsorption and photoionization cross sections across the K edge of the Li-like to Ca-like ions stages of Ni. Level-resolved, Breit-Pauli ca…
Modeling the oxygen K absorption in the interstellar medium: an {\it XMM}-Newton view of Sco X-1
J. García, J. M. Ramírez, T. R. Kallman +5
We investigate the absorption structure of the oxygen in the interstellar medium by analyzing {\it XMM}-Newton observations of the low mass X-ray binary Sco X-1. We use simple mode…
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…
