| Description |
The third version of the XMM-Newton slew survey catalogue, XMMSL3, has been released on 19th February 2025 by the XMM-Newton Survey Science Centre (XMM-SSC) in collaboration with the SOC. This version includes an extra 8.5 years of data with respect to XMMSL3. There are 140735 X-ray detections which relate to 116598 unique sources, doubling the number of detections available in the previous version, XMMSL2. These detections come from 3120 pn slew observations that were taken by the 23rd Auguest 2023. This catalogue version covers more than 90% of the sky, where some regions of the sky have been pointed as many as 78 times. Around 8% of all the detections are classified as extended. The median positional uncertainty of the clean catalogue detections is 4 arcseconds. Median fluxes in the catalogue are ~1.1E-12 and ~9.0E-12 erg/cm2/s in the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively. |

| Mission description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) is ESA’s flagship of high-energy astronomy. Launched by an Ariane 504 on December 10th 1999, it is ESA’s second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations and a long baseline for multiwavelength timing analysis. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission looks deep into galaxy centres, studies stars at all stages of their lives, follows up on explosive events, investigates what happens around black holes and in this way allows us to learn how the Universe was formed and evolved, and how matter behaves under the most extreme conditions. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
