09 July 2024 * Contents: [1] New release of the XMM-Newton Serendipitous Source Catalogues, 4XMM-DR14 and 4XMM-DR14s * 1. New release of the XMM-Newton Serendipitous Source Catalogues, 4XMM-DR14 and 4XMM-DR14s More than a million X-ray detections in the XMM-Newton 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 if overlaps are taken into account, where some regions of the sky have been pointed as many as 90 times. Around 9% of all the detections are classified as extended, and spectra and time series have been extracted for 36% of the detections. The median positional uncertainty of the catalogue detections is 1.57 arcseconds (with a standard deviation of 1.43). Median fluxes in the catalogue are ~5.2E-15 and ~1.2E-14 erg/cm2/s in the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively. 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. Stacking results in better source parameters, higher sensitivity, and direct access to measures of long-term flux variability. 4XMM-DR14s is built from 1751 groups drawn from 10332 observations. Stacked source detection is performed on all overlapping exposures of reasonable quality. For lower-quality exposures, parameters are provided from PSF photometry. 4XMM-DR14s contains 427524 sources, of which 329972 have several contributing observations. From the individual observations, 1.8 million flux measurements (and related parameters) of all the sources are derived in total during stacked source detection and photometry. 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. The detection catalogue is described in the paper Webb et al. (2020) and the stacked catalogue is further described in Traulsen et al. (2020). Details of the catalogue, the catalogue files and full 4XMM documentation are available on the XMM-SSC webpages (https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fxmmssc.irap.omp.eu%2F&data=05%7C02%7Cxmmnews%40lists.nasa.gov%7C5c2a9779e4ad4d40e06a08dca0562143%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638561538995593047%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=hP3tENSkt95HKEgrqUwYiC0UVpKxH9Yh%2BZTWAmZ7eUw%3D&reserved=0) at: https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fxmmssc.irap.omp.eu%2FCatalogue%2F4XMM-DR14%2F4XMM_DR14.html&data=05%7C02%7Cxmmnews%40lists.nasa.gov%7C5c2a9779e4ad4d40e06a08dca0562143%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638561538995593047%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=caxBUKsrAHjewEMiRZ1FSNOXBBJfudxrBF1GT%2B0uHMA%3D&reserved=0 and https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fxmmssc.aip.de%2Fcms%2Fcatalogues%2F4xmm-dr14s%2F&data=05%7C02%7Cxmmnews%40lists.nasa.gov%7C5c2a9779e4ad4d40e06a08dca0562143%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638561538995593047%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=UwQvNkM7X7%2Be%2FlNsGEhrz2wvEURl0k7Ua2WJl7Sui9E%3D&reserved=0 FITS files containing summary information about the observations used in the catalogue are also provided.
