Presentation #332.04 in the session Laboratory Astrophysics Division (LAD): World of Databases II.
The soon to be launched X-Ray Imaging and Spectroscopy Mission will host a microcalorimeter with an unprecedented photon energy resolution approaching 5 eV. As the only operating space-based microcalorimeter, it will place enormous pressure on the accuracy of fundamental atomic data needed to interpret and model X-Ray observations. To aid in modeling X-Ray emission due to charge exchange (CX), we have developed a convenient interface for our spectral simulation package Kronos and enhanced its underlying database. The database includes CX cross sections for all emitting H-like and He-like ions from C to Zn, many Li-like ions, and all Fe ions with initial charges q=16-26 interacting with a range of neutrals (H, He, H2, H2O, CO, CO2, N2, O). The emission model simulates an optically thin plasma and uses spectroscopic parameters from evaluated experimental data from the NIST Atomic Spectral Database supplemented by hydrogenic models and AUTOSTRUCTURE calculations. Example spectra will be presented for comets, supernova remnants, and AGNs. This work partial supported by NASA grants 80NSSC22K1168 and 80NSSC23K0648.
