CAIXA ivo://nasa.heasarc/caixa NASA/GSFC HEASARC Bianchi et al. 2026-05-08 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov AGN This table comprises CAIXA, the "Catalog of AGN In the XMM-Newton Archive". It consists of all the radio-quiet, X-ray unobscured (N<sub>H</sub> < 2 x 10<sup>22</sup> cm<sup>-2</sup>) active galactic nuclei (AGN) observed by XMM-Newton in targeted observations, whose data were public as of March 2007. With its 156 sources, this is the largest catalog of high signal-to-noise X-ray spectra of AGN. All the EPIC pn spectra of the sources in CAIXA were extracted homogeneously, and a baseline model was applied in order to derive their basic X-ray properties. These data are complemented by multiwavelength data found in the literature: black hole masses, full width half maximum (FWHM) of H(beta), radio and optical fluxes. In their paper, the authors describe their homogeneous spectral analysis of the X-ray data in CAIXA and present all the results for the parameters adopted in their best-fit models. This table was created by the HEASARC in March 2009 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/495/421">CDS catalog J/A+A/495/421</a> files table1.dat, table2.dat and table3.dat.
