Q&A: Chandra Mission
Relating to X-ray absorption spectroscopy: Because of X-ray data
coming from new telescopes such as Chandra, laboratory
experiments are a good test bed for extreme plasma conditions,
for which there are no known models. Could you point out a
marking example of data coming out from Chandra that constitutes
a challenge for plasma atomic physics?

A few of the many recent observations with Chandra that show
the richness of the spectra, and the need for more precise
calculations are given below. In general, Chandra is
demonstrating the need for better theoretical X-ray spectra
for a wide variety of objects, including comets & planets
(fluorescence and charge-exchange) to stellar coronas,
supernova remnants (non-equilibrium effects are especially
important here), accretion disks around stellar and
supermassive black holes, and galaxy clusters.
