Postdoctoral position in High-Energy Astrophysics in Strasbourg (France) XMM2ATHENA

We invite applications for a postdoctoral position at Strasbourg Astronomical Observatory (ObAS) to participate in the EU-funded project H2020 SPACE  XMM2ATHENA. The ObsAS harbours the Centre de Donnees astronomiques de Strasbourg (CDS) and is one of the member institutions of the XMM-Newton Survey Science Centre (SSC). The institute is also actively involved in future projects such as SVOM, IXPE, eXTP and Athena.

XMM2ATHENA is a collaboration of 9 European Institutes including members of the XMM-Newton SSC to develop innovative methods to maximize the return from the current X-ray observatory XMM-Newton and prepare for the forthcoming X-ray mission Athena.

The postdoc will lead efforts to expand the functionalities of the statistical multi-wavelength cross-matching software developed by the ARCHES FP-7 European project formerly led by Strasbourg. The improved identification and classification tool is key for the project. We also expect the successful applicant to actively take part in the scientific exploitation of this tool; Scientific interests close to those of the hosting team (X-ray binaries, ULXs, X-ray source populations in the Milky Way, the Magellanic Clouds and nearby galaxies) would be welcome.

The applicant is expected to have a PhD in Physics or Astronomy, experience in high energy astrophysics and programming skills. The salary is based on the French public service scale and the applicant’s previous experience. Additional funding for conferences, collaboration, personal equipment and publication is available. The position includes full access to the French healthcare system (medical and dental, sick leave, maternity leave) and pension fund. The initial appointment is for one year, starting before April 2023, with the possibility of extension for a second year depending on availability of funds. 

Candidates should send a curriculum vitae, a list of publications, a summary of research interests (2-3 pages max) and contact details of two referees to Ada Nebot ( before the 9th of January 2023. Late applications will be cosidered. ObAS is an equal-opportunity employer. We encourage applications from women and minorities.

PostDoctoral Position

H2020 SPACE XMM2ATHENA postdoctoral position


Applications are invited for a post-doctoral position at the Institute of Astronomy Astrophysics Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens (NOA). The successful applicant will closely collaborate with the X-ray group of the IAASARS (Dr. Akylas, Dr. Georgantopoulos, Dr. Georgakakis) to develop novel tools, largely based on Artificial Intelligence algorithms, that will generate value-added products (e.g. photometric redshifts, upper limits) for the 4XMM serendipitous source catalogue. The scientific exploitation of these products will also be part of the contract. 

The position is funded by the EU H2020 XMM2ATHENA project. It brings together 9 European nodes with extensive expertise in high energy astrophysics, including members of the XMM-Newton and Athena Science ground segments, to develop innovative X-ray analysis methods and algorithms. These will be tested on existing XMM-Newton data and will form the basis for the Athena data analysis software, currently at the beginning of the developmental phase. 

Preferred qualifications include  a PhD in Astronomy, Astrophysics or related field by the start date as well as experience in (i) high energy astrophysics, (ii) programming of complex algorithms with emphasis on machine/deep learning, (iii) handling of large multiwavelength datasets and (iv) population studies of extragalactic sources.

The post is for 18 months, starting in early 2022. For informal inquiries please contact Dr. Thanassis Akylas (

Interested candidates can apply via email by sending a curriculum vitae, a summary of research interests (limited to 3 pages) and a list of publications (all as pdf files) to the secretary before Oct. 15th  2021. Please also arrange for two letters of reference to be sent to the same email address by the above deadline. NOA is an equal-opportunity employer. We encourage applications from women and minorities.

Additional Benefits: Funding for conference and collaboration traveling, personal equipment and publication costs is available. The position includes full access to the Greek healthcare system and pension fund.
