Enhanced XMM-Newton Spectral-fit Database


The aim of this project is to:

  1. expand our XMMFITCAT project to the newly available 3XMM sources;
  2. derive photometric sources for all X-ray extragalactic sources with reliable optical counterparts in the SDSS or Pan-STARRS catalogues (XMMPZCAT);
  3. re-run the X-ray spectral fits taking into account the photometric redshift information (XMMFITCAT-Z).

Thanks to this project we can untap the full potential of XMMFITCAT: using the distance information (redshifts) we can derive rest-frame column densities, rest-frame energies of emission and absorption features, temperature of emitting plasma and luminosities.

This project is funded by the ESA-PRODEX program and consists of the collaboration between the X-ray Astronomy and Cosmology group group at the Institute for Astronomy, Astrophysics, Space Applications, and Remote Sensing (IAASARS) at the National Observatory of Athens (NOA), the X-ray and Observational Astronomy Group (XROA) at the Department of Physics and Astronomy at the University of Leicester, the Galaxies and AGNs group at the Instituto de Física de Cantabria, the Galaxies, High Energy and Cosmology (GAHEC) department at the Institut de Recherche en Astrophysique et Planétologie (IRAP), the Department of Astronomy at the University of Geneva, and the XMM-Newton Science Survey Centre (SSC).



Any publication based on data from the enhanced XMM-Newton spectral-fit database should acknowledge the use of this database as well as the use of XMM-newton data in the acknowledgement section:

"Based on results from the enhanced XMM-Newton spectral-fit database, an ESA PRODEX funded project, based in turn on observations obtained with XMM-Newton, an ESA science mission with instruments and contributions directly funded by ESA Member States and NASA".

In addition, publications using the XMMFITCAT should include a reference to Corral et al. (2015), A&A, 576, 61. The use of the XMMPZCAT should refer to Ruiz et al. (2018), A&A, 618, 52.. The use of the XMMFITCAT-Z should refer to Ruiz et al. (2021), A&A, 645, A74.
