| Post-doctoral position in neutron stars astrophysics at IRAP (Toulouse, France) | Closing date: 2026-03-31
Contact: Sebastien Guillot |
The Institute for Research in Astrophysics and Planetology (IRAP) in Toulouse (France) invites applications for a postdoctoral position to work on neutron star modelling and observations funded by the French National Research Agency (Agence Nationale de la Recherche) through the DENSeR project. The application deadline is March 31st.
All details for the position and application procedure are below and are also available here:
http://userpages.irap.omp.eu/~sguillot/files/PostDoc_JobAnnoucement_ANR_DENSeR.pdf | | ▸ more | Context
Neutron stars, the dense remnants of the core-collapse of massive stars, are unique laboratories to study the strong force in physics. With the densities attained inside neutron stars (beyond the density of atomic nuclei), astrophysicists can study the composition and behaviour of stable states of dense matter and constrain nuclear physics theory. This also opens up the possibility of exploring strange or exotic states of matter, which may only exist inside neutron stars. To do so requires measuring their masses and radii, the macroscopic properties that are linked to the interior pressure and density of neutron stars via an equation of state. One promising method to do so arose from the analysis of the X-ray pulse profile of millisecond pulsars obtained from the NICER X-ray telescope. By exploiting the effects of general relativity on the trajectory of photons leaving the NS surface, one can determine the neutron star compactness (and therefore the mass and radius) from the modelling of the X-ray pulse profile. However, current measurements have relied on a number of assumptions that can potentially bias the inferred masses and radii. Several avenues are being studied to improve the reliability of these measurements, in particular those made with the software X-PSI (X-ray Pulse and Simulation and Inference, ...).
Activities
The successful candidate will be leading some work packages of the ANR DENSeR, notably regarding the modelling of the neutron star surface emission regions to compare to X-ray observational data. The optimisation of the existing models (in X-PSI) will be necessary, as well as the inclusion of GPU and/or Machine Learning capabilities for the simulation and inference. These improvements of the neutron star surface emission modelling will be quantified with actual data (from the NICER telescope) and with simulated data from upcoming instruments (such as NewAthena). Part of this work will be done in collaboration with researchers at the University of Amsterdam and at the University of Helsinki (Finland).
Some time for the successful candidate's own research should also be possible. The research interests of the group include neutron stars, X-ray binaries, Ultra Luminous X-ray sources (ULXs), gamma-ray bursts and merging compact objects, including massive black hole binaries.
Profile
The applicant should have a PhD in Astrophysics (or closely related fields), ideally with experience in X-ray and/or neutron star astrophysics. The ability to work collaboratively and within an interdisciplinary framework will be a crucial element in the application assessment. A very good level of written and spoken English is expected as this work will be done in the context of an international collaboration. The applicants should have knowledge of Python programming, and knowledge of C/C++ (or Cython) would be advantageous. Additionally, some experience with the modelling of neutron stars, or GPU, or Machine Learning could be appreciated.
Position description
The position is for a full-time commitment, with an initial contract for one year, renewable once, and with a negotiable start date in October 2026.
Compensation will be commensurate with experience, with gross monthly salary ranging between ?2800 and ?3900. The position includes full access to the French healthcare and welfare system (medical and dental, sick leave, parental leave, family allowances for children, pension and unemployment benefits).
Additional funding for conferences, collaboration, and personal equipment is available through the DENSeR project or other sources of funding at IRAP.
The IRAP offices are part of a Restricted Area Regime (ZRR ? Zone ŕ Régime Restrictif). After the selection procedure, this access authorisation (to be granted by the competent authorities) will be required to establish the work contract.
Application procedure
Applicants should deposit a single PDF file by the deadline of March 31st, on the following webpage: https://sdrive.cnrs.fr/s/iSda6xDoR28KHPi
The application file should include, in order:
- A brief cover letter (1 page)
- A curriculum vitae (maximum 2 pages)
- A list of publications, conference presentations, etc. (no page limit)
- A personal and research statement (see details below)
The personal and research statement should present the applicant's research experience, research interests, and outline their motivation to work with us at IRAP. The maximum is 4 pages, but shorter statements (1-2 pages) will be assessed depending on the level of experience of the applicant.
Reference letters
In order to not burden reference letter writers with an excessive load, we only ask, at this stage, for names, positions, email addresses and telephone numbers of three referees/colleagues who have agreed to write reference letters. These will only be requested from short-listed candidates.

| 2+1 year postdoctoral position on detection of strongly-lensed supernovae in Rubin/LSST data in Marseille, France | Closing date: 2026-03-31
Contact: Stéphane Blondin |
The Laboratoire d'Astrophysique de Marseille (LAM) invites applications for a postdoctoral research associate position focused on the search of lensed supernovae with Rubin/LSST. The successful candidate will join the international French-German project "SuperEarly: Constraining Supernova Progenitors through Strong Lensing in the Rubin LSST Era".
- Starting date: September 2026
- Duration: 2 years initially + possible 1 year extension (fully funded)
- Salary range (depending on experience): 3130-4340 EUR / month (gross) + employee benefits
- Application deadline: 31st March 2026 | | ▸ more | *** Project background and description ***
A strongly lensed SN offers a unique opportunity to access the first hours/days of its evolution, providing key information on the progenitor and explosion mechanism. The Vera Rubin Observatory is expected to discover more than 100 lensed SNe of all types during its ten-year Legacy Survey of Space and Time (LSST). Our three-year project SuperEarly will allow us to obtain the earliest rest-frame UV observations of SNe ever made. Our complementary expertise in deep-learning classification, lens and SN modelling, combined with our access to LSST data and follow-up facilities, will yield unprecedented constraints on the progenitors of all types of SNe shortly after they explode.
The main task will be to lead the development of advanced deep-learning methods to discover the rare gravitationally lensed supernovae in Rubin/LSST data. This work will be done with the support from the machine learning division of the LAM data centre. The candidate will also contribute to the observational follow-up of confirmed lensed SNe, and to the comparison with synthetic spectra and light curves of SNe at early phases. The resulting catalog of static gravitational lenses, and the candidate and confirmed lensed SNe will be key for the overall project on constraining SN progenitors and will have a value for the overall community.
Our proposed project builds upon the results from the HOLISMOKES program (http://www.holismokes.org/) that was funded by the European Research Council until May 2024. The PI of that program, Sherry Suyu (TUM/MPA, Germany), is also part of the project team. At LAM, in addition to the project co-PI J.-C. Bouret, the postdoc will also work closely with postdoc Raoul Cańameras (expert on deep-learning algorithms to search for lensed supernovae) and a PhD student to be recruited for this project. There will be regular collaboration visits (twice per year) to our German collaborators on the Garching campus near Munich, Germany. There would also be a possibility for more extended visits (up to 1 year, TBD) at the European Southern Observatory (ESO) on the same campus, where the co-PI S. Blondin is also located. The postdoc will benefit from full data access rights to the Rubin/LSST project.
Keywords: Supernovae ? Gravitational lensing ? Radiative transfer ? Deep learning ? Transient surveys
*** Work Environment ***
The Laboratoire d'Astrophysique de Marseille (LAM, https://www.lam.fr) is a multidisciplinary research institute jointly funded by CNRS (the French National Research Center), CNES (the French Space Agency), and Aix-Marseille University (amU). At LAM, the successful candidate will join the GECO (Galaxies, Stars, and Cosmology) team, which comprises approximately 60 members, about half of whom are PhD students and postdoctoral researchers. A significant fraction of the team comes from outside France. Within GECO, a rapidly growing Transients subgroup brings together researchers working on gamma-ray bursts (GRBs; progenitors and host galaxies), fast radio bursts (FRBs), black holes, and related topics.
*** Requirements ***
Applicants should:
- Hold a PhD in Astronomy or Astrophysics by June 2026
- Have experience in Machine Learning and Deep Learning techniques
- Possess computing skills and/or observational experience
Experience with Supernovae, GRBs and other peculiar transients will be particularly valued. Teaching experience, student supervision are considered assets but are not required.
