Soft X-Ray Absorption by Fe to Fe in Active Galactic Nuclei

Ehud Behar, Masao Sako, Steven M. Kahn

A full set of calculations is presented for inner-shell n = 2 to 3 photoexcitation of the 16 iron charge states: Fe I through Fe XVI. The blend of the numerous absorption lines ari…

Dielectronic Recombination (via N=2 --> N'=2 Core Excitations) and Radiative Recombination of Fe XX: Laboratory Measurements and Theoretical Calculations

D. W. Savin, E. Behar, S. M. Kahn +13

We have measured the resonance strengths and energies for dielectronic recombination (DR) of Fe XX forming Fe XIX via N=2 --> N'=2 (Delta_N=0) core excitations. We have also calcul…

Soft X-ray Spectroscopy of Seyfert 2 Galaxies

A. Kinkhabwala, M. Sako, E. Behar +6

Soft X-ray spectroscopy of Seyfert 2 galaxies offers perhaps the best method to probe the possible connection between AGN activity and star formation. Obscuration of powerful radia…

Confronting atomic data with Fe L-shell spectra of stellar coronae

E. Behar, J. Cottam, J. R. Peterson +5

It is common to suggest the uncertainties in the atomic data for explaining difficulties that arise in interpreting astrophysical x-ray spectra. The atomic data for the Fe L-shell…

A physically consistent model for X-ray emission by Seyfert 2 galaxies demonstrated on NGC 1068

E. Behar, A. Kinkhabwala, M. Sako +5

Preliminary analysis of the X-ray spectrum of NGC 1068 obtained by the RGS spectrometer on board XMM-Newton is presented. A physically consistent model is developed in order to qua…
