Welcome to the XMM-Newton Science Operations Centre

 

The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton 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.

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 is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.

News and Highlights

Astronomers investigate Astronomers investigate the evolution of a supersoft X-ray source 28-Nov-2024
Using ESA's XMM-Newton satellite and NASA's Chandra spacecraft, German astronomers have observed a supersoft X-ray source designated RX J0513.9−6951. Results of the observations, published on the arXiv preprint server, shed more light on the evolution of this source.

Unlocking the secrets of the first Quasars Unlocking the secrets of the first Quasars: how they defy the laws of Physics to grow 20-Nov-2024
New evidence has been discovered explaining how supermassive black holes formed in the first billion years of the Universe's life. The study, conducted by INAF researchers, analyses 21 distant quasars and reveals that these objects are in a phase of extremely rapid accretion. This provides valuable insights into their formation and evolution, together with that of their host galaxies.[...] The study, led by researchers of the National Institute for Astrophysics (INAF), analyses a sample of 21 quasars, among the most distant ever discovered, observed in the X-rays band by the XMM-Newton and Chandra space telescopes.

Quasi-periodic eruptions Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds 11-Nov-2024
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated period of over three and a half years. The finding was reported November 1 on the pre-print server arXiv.[...] Follow-up observations of eRO-QPE2 with ESA's XMM-Newton satellite have revealed that it exhibits QPEs with intrinsic luminosities oscillating between approximately 0.12 and 1.2 tredecillion erg/s in the 0.5–2-keV band.

XMM-Newton Announcement of Opportunity (AO-24) Closed

The XMM-Newton Twenty-fourth Announcement of Opportunity (AO-24) closed on the 11th of October 2024.

In total, 462 valid proposals were received. This Announcement of Opportunity covers a period of one year, with 12 Ms of observing time available for distribution. A total of 86.3 Ms of science time were requested. The over-subscription factor is 7.2.

A total of 36 proposals were received for Large Programmes, and 13 for Fulfil Programmes. Anticipated Target of Opportunity observations were requested in 65 proposals.

For the joint programmes, 94 proposals were submitted: 42 request time for the XMM-NuSTAR programme, 24 for the XMM-HST programme, 11 for the XMM-SWIFT programme, 10 for the XMM-VLT programme, 9 for the XMM-Chandra programme, 6 for the XMM-JWST programme, 10 for the XMM-NRAO programme and 1 for the MAGIC programme.

SOC received proposals from 381 different principal investigators from 32 countries. Considering principal investigators and co-investigators, about 1600 individual scientists were involved in the response to the Twenty-fourth Announcement of Opportunity.
