The available atomic data used for interpreting and modeling x-ray observations are
reviewed. The applications for these data can be divided into several levels of detail …

We describe the latest release of AtomDB, version 2.0. 2, a database of atomic data and a
plasma modeling code with a focus on X-ray astronomy. This release includes several major …

The CHIANTI atomic database contains atomic energy levels, wavelengths, radiative
transition probabilities, and collisional excitation data for a large number of ions of …

We calculate the efficiency of iron K line emission and iron K absorption in photoionized
models using a new set of atomic data. These data are more comprehensive than those …

We report calculations of energy levels, radiative rates, and electron impact excitation rates
for transitions in Li-like ions with 12≤ Z≤ 20. The grasp (general-purpose relativistic atomic …

As part of a project to compute atomic data for the spectral modeling of iron K lines, we
report calculations and comparisons of atomic data for K-vacancy states in Fe xxiv. The data …

Spectroscopic observations made by the Extreme Ultraviolet Variability Experiment (EVE) on
board the Solar Dynamics Observatory (SDO) during the 2012 March 7 X5. 4-class flare …

The determination of a good relative and absolute sensitivity calibration for wideband VUV
spectrometers is challenging. On JET, the possible T and Be contamination of the VUV …

We report calculations of energy levels, radiative rates and electron impact excitation cross
sections and rates for transitions in He-like Cl XVI, K XVIII, Ca XIX and Sc XX. The GRASP …

We analyze the physical processes that should be taken into account when modeling young
type-Ia supernova remnants (SNRs) with ages of several hundred years in which forward …
