Photoionization, fluorescence, and inner-shell processes

Major advances in state-of-the-art theoretical methods coupled with advances in computational architectures have opened the doorway to large-scale computations on elements across the periodic table, allowing the inclusion of fully relativistic effects. Whenever possible results have been benchmarked against high resolution measurements obtained from either synchrotron radiation facilities or satellite observations. Various stages of ionization, necessary for the many applications in astrophysics, can be studied in the absence of experimental values to obtain the necessary data. A simple review is presented of photoionization, fluorescence and inner-shell processes recently investigated.
