Category: SPEX CODE

History

Starting in the early seventies (Mewe 1972) Rolf Mewe and his colleagues of the Space Research Laboratory in Utrecht started developing a spectral code for the X-ray emission of optically thin plasmas. A milestone was reached in 1985 and 1986, when two papers describing the line emission (Mewe et al. 1985) and continuum emission (Mewe …

Spectral line lists For convenience of users, a list of spectral lines with intensities has been produced. This list may serve primarily as a quick guide to identify lines in an observed spectrum and to recognize the most important lines at a given temperature. This list should not be used to produces specific emissivity codes, …

SPEX

SPEX is an X-ray spectral analysis software package optimized for the interpretation of high-resolution astrophysical X-ray spectra. The software is especially suited for fitting spectra obtained by current X-ray observatories like XMM-Newton, Chandra, Suzaku, and Hitomi. SPEX will be continuously improved to handle spectra from high-resolution X-ray instruments on future missions like Athena. The advantages …
