New version of the XMM-Newton EPIC Serendipitous Source Catalogues: 4XMM-DR14 and 4XMM-DR14s

A new version of the XMM-Newton EPIC Serendipitous Source Catalogue, 4XMM-DR14, has been released by the XMM-Newton Survey Science Centre (XMM-SSC) in collaboration with the XMM-Newton SOC.This version includes an extra year of data with respect to 4XMM-DR13. 4XMM-DR14 now has over a million X-ray detections (1035832) which relate to 692109 unique X-ray sources from 13864 observations that were public by the 31st December 2023. 4XMM-DR14 covers a total sky area, with at least 1 ks exposure, of 1383 square degrees.

With the detection catalogue 4XMM-DR14, we release the stacked catalogue 4XMM-DR14s, created from overlapping observations. Some sources have a total of ~3 Ms of observation. 4XMM-DR14s is built from 1751 groups drawn from 10332 observations. 4XMM-DR14s contains 427524 sources, of which 329972 have several contributing observations. 4XMM-DR14s reaches a median depth of ~2.5E-15 and ~6.8E-15 erg/cm2/s in the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively. 7798 sources are variable on the long term.
