[22 September 2023] To celebrate this year’s European Researchers Night, we have prepared an international contest to learn about X-ray astronomy using the Quizizz platform. This contest is a joint international initiative of the following projects: the XMM2Athena project, the Athena Community Office, the Athena/X-IFU and Athena/WFI instruments consortia, and the AHEAD2020 project. The Quizizz…

A new version of the XMM-Newton EPIC Serendipitous Source Catalogue, 4XMM-DR13, has been released by the XMM-Newton Survey Science Centre (XMM-SSC) in collaboration with the SOC. This version includes an extra year of data with respect to 4XMM-DR12. 4XMM-DR13 includes 983948 X-ray detections which relate to 656997 unique X-ray sources from 13243 observations that were…

Pooja works in WP2 expanding the functionalities of the statistical multi-wavelength cross-matching software developed by the ARCHES FP-7 European project and in the scientific explotation of this tool.
Postdoctoral position at Strasbourg Astronomical Observatory The Observatory is one of the member institutions of the XMM-Newton Survey Science Centre (SSC) and it also harbours the CDS (Centre de Données astronomiques de Strasbourg). The SSC group is also actively involved in future missions such as SVOM and Athena or projets such as XMM2Athena. Within the…

Ultra-/hyperluminous X-ray sources (ULX/HLX) could be interesting laboratories to further improve our understanding of the supermassive black hole growth through super-Eddington accretion episodes and successive mergers of lighter holes. ULXs are thought to be powered by super-Eddington accretion onto stellar-mass compact objects, while HLXs may be accreting intermediate mass black holes (IMBH). However, a significant…

Tidal disruption events (TDEs) occur when a star passes close to a massive black hole, so that the tidal forces of the black hole exceed the binding energy of a star and cause it to be ripped apart. Part of the matter will fall onto the black hole, causing a strong increase in the luminosity.…

XMM-Newton, a European Space Agency observatory, has been observing the X-ray, ultra-violet and optical sky for 23 years. During this time, astronomy hasevolved from mainly studying single sources to populations and from a single wave-length, to multi-wavelength/messenger data. We are also moving into an era of timedomain astronomy. New software and methods are required to…

The Strasbourg Observatory has developed a new XCatDB feature, named Amora for “Asynchronous Multi-Observation Region-based Analysis”. Amora allows users to access all the events/photons that were collected by the XMM-Newton mission in the region of interest and to process them interactively. Users can draw a polygon or a circle isolating that region ; they can…
