For the community

The X-IFU Consortium produced several resources that are made available to the scientific community.

X-IFU response matrices (2023)

Following the reformulation of the Athena mission, a new set of X-IFU resources is now available for download at the link below. Check the INSTRUCTIONS.README file for a description of the response files distributed.

Mirror resource products for the baseline mission configuration are available from :

You will find information on the instrument efficiency assumed in generating these response files in Barret et al. (Experimental Astronomy, 2023). Please refer to this paper if you intend to use those response files in your work. Thanks !

Download the .arf and .rmf files


X-IFU non X-ray background files (2023)

The X-IFU non X-ray background files were originally produced by the IAPS/INAF group led by Simone Lotti. They are provided for different extraction regions. See the INSTRUCTIONS.README for use. Please see Lotti et al. (The Astrophysical Journal, 2021) for a review of the X-IFU particle background.

SIXTE files related to X-IFU (2023)

SIXTE is a software package for X-ray telescope observation simulations developed at the Remeis Observatory (ECAP). It allows to undertake instrument performance analyses and to produce simulated event files for X-IFU and other instruments. The formal repository for files used by SIXTE for the reformulated X-IFU is here. They are provided to the community by Edoardo Cucchetti, X-IFU performance manager.
