» Simulations of X-Ray Telescopes for eROSITA and IXO
Presenter: Christian Schmid
We present a generic X-ray instrument simulation tool developed for studies of future X-ray missions. According to the concept of Monte Carlo simulations the software generates a sample of photons for different X-ray sources based either on several catalogs like the ROSAT all-sky survey or on images of light cones from cosmological hydrodynamical simulations. The imaging in a Wolter telescope and the detection process are modelled by means of standard calibration files like a point spread function and the detector response. The resulting event files have FITS format and can be analysed with standard tools. With this software we have done simulations of parts of the eROSITA all-sky survey for several fields of galaxy clusters, and we have studied the detector-specific pile-up behaviour for the High Time Resolution Spectrometer and the Wide Field Imager on the International X-ray Observatory.
