xmm_simulator generates mock XMM-Newton images and spectra from 3D galaxy cluster simulations from hydrodynamical simulations. It generates particle background spectra from filter-wheel-closed data, a realistic sky background model, energy-dependent vignetting, energy redistribution, and PSF convolution. Users can extract lists of simulated events, corresponding photon images, exposure maps, non-X-ray background maps, and spectra with redistribution matrices and weighted ancillary responses. xmm_simulator also includes tools to sum maps from multiple instruments and to organize simulation outputs into FITS files suitable for further analysis.

Hydromass analyzes galaxy cluster mass profiles from X-ray and/or Sunyaev-Zel’dovich observations. It provides a global Bayesian framework for deprojection and mass profile reconstruction, including mass model fitting, forward fitting with parametric and polytropic models, and non-parametric log-normal mixture reconstruction. Hydromass easily loads public X-COP data products and applies reconstruction tools directly within a Jupyter notebook.
