▸ more
ESO astronomers are participating in the design of a new facility, the Wide-field Spectroscopic Telescope (WST: https://www.wstelescope.com/, https://arxiv.org/abs/2403.05398), an innovative 12-m class wide-field spectroscopic telescope with simultaneous operation of a large field-of-view (3 sq. degree) and high multiplex (30,000) multi-object spectrograph facility with both medium and high resolution modes (MOS), and a giant panoramic (3x3 sq. arcmin) integral field spectrograph (IFS). The WST project is a research and innovation action funded by the EU's Horizon Europe programme (under agreement number 101183153 (WST)). Under this agreement, ESO is offering a postdoctoral researcher the opportunity to work on time-domain science with WST. Time-domain astronomy is a key component of WST's science drivers, and thus, it is being built into WST from the start. This includes the generation and ingestion of a spectroscopic alert stream, which aims to report on spectral changes, like variations in emission or absorption lines or changes in the continuum, among others. The development of this alert stream will be conducted in the context of the WST time-domain working group (led by Richard Anderson - EPFL, Cyrielle Opitom - University of Edinburgh, and Paula Sanchez Saez - ESO), whose aim is to maximize the information offered by WST time-resolved observations, enabling breakthrough science across all scales, from Solar System Objects to Cosmology, and offering a major opportunity for serendipitous discoveries. In this context, the postdoctoral fellow will work for one year on the definition and characterization of the WST spectroscopic alert stream. Main Duties and Responsibilities: Work in close collaboration with members of the WST Time-Domain group on the definition of the WST alert stream. Interact with other members of the WST Time-Domain group to collect requirements for the alert stream. Collect available optical spectra for classes of targets for which the alert stream is relevant. Use the WST ETC to simulate optical spectra for testing. Estimate expected alert rates. Provide inputs to the operational model team. Develop and test algorithms for the identification of spectral changes. Key competencies and requirements Essential Competences and Experience: Experience with optical spectral analysis Good working knowledge of Python. Experience with statistical analysis in astronomy Desirable Competences and Experience: Strong background in time-domain astronomy Experience with large spectroscopic surveys. Experience with multi-object spectroscopy (MOS) or integral field spectrograph (IFS) observations Background in machine learning applied to astronomy Experience with photometric alert streams (e.g., ZTF or LSST) Qualifications: Applicants must have a PhD in astronomy, physics or a related discipline by 1 October 2025. Language Skills: The position requires an excellent command of English, both written and spoken. Remuneration and Contract: We offer an attractive remuneration package including a competitive salary and allowances, comprehensive social benefits, and we provide financial support for relocating families. Salary will be in line with ESO Fellow salaries. The position includes the benefits as outlined under https://www.eso.org/public/jobs/conditions/fellows/ however, the duration of the contract is limited to one year. The starting date is flexible, but should not be later than December 2025. Duty Station: Garching near Munich, Germany. Application: If you are interested in working in areas of frontline science and technology and in a stimulating international environment, please visit http://www.eso.org for further details. Applicants are invited to apply online at: https://recruitment.eso.org. Applications must be completed in English and should include the following material: A Cover Letter of up to one page outlining relevant experience and motivation for the role; A research statement of up to two pages; A CV including personal data, education, skills, expertise, and publication list; The position also requires two letters of reference to be submitted. Referees will be automatically invited to submit a recommendation letter by the application deadline. Applicants are strongly advised to trigger these invitations (using the web application form) well in advance of the application deadline. Deadline for applications is 20 June 2025.

Postdoctoral Position in Galactic Archaeology	Closing date: 2025-05-31 Contact: Nad�ge Lagarde
We invite applications for one postdoctoral position at the Bordeaux Laboratory for Astrophysics, France, to work on the characterisation of old Galactic stellar populations.
▸ more
The successful candidate will join the research team led by Dr N. Lagarde and work on PRIMA (PRobing the origIns of the Milky WAy's oldest stars), a project funded by the French National Research Agency (ANR) and the Swiss National Science Foundation (SNSF). PRIMA is an international collaboration with a team led by Prof. C. Charbonnel at the Department of Astronomy of the University of Geneva, Switzerland. PRIMA focuses on the Galactic structures hosting the oldest stars of the Milky Way, namely the halo, thick disc, and globular clusters (GC), which are key tracers of the Galaxy's merger history. The project employs stellar population synthesis models to simulate the present-day stellar content of the Milky Way, combining state-of-the-art stellar evolution models with Galactic formation scenarios. By comparing simulated mock catalogues with multi-wavelength survey data, including Gaia data combined with spectroscopic and asteroseismic constraints, PRIMA offers a unique perspective on Galactic evolution. Unlike other approaches, it eliminates selection biases in data analysis and accounts for internal stellar processes that alter chemical abundances and impact stellar lifetimes. The project aims to disentangle in situ and ex situ origins of old stars and to assess the effects of mergers and secular evolution (e.g., radial migration) on Galactic stellar populations, including globular clusters and their escaped stars. The postdoctoral researcher based in Bordeaux will focus on characterising and dating merger events in the halo and thick disc, using the Besan�on Galactic Model (BGM), a well-established Galactic stellar population synthesis tool. We seek a highly motivated and creative researcher capable of developing new strategies to interpret Galactic surveys and correct for selection biases to better understand the oldest stellar populations of the Milky Way. We welcome applications from candidates with expertise in observational, theoretical, or computational astrophysics, particularly in the fields of stellar and Galactic evolution. The ideal candidate has good knowledge of English and solid programming skills. We treasure diversity in the Prima�collaboration and strive to foster an inclusive, collegial and supporting environment where anyone can feel welcome and valued regardless of background or identity. Position Details - Duration: 2 years - Starting Date: Autumn 2025 (flexible within reasonable limits) - Location: Laboratoire d'Astrophysique de Bordeaux, University of Bordeaux, France - Benefits: Full health insurance and social security coverage (as per French law) - Funding: Support for travel to international conferences and collaborations Application Process Applicants should submit the following documents in a single PDF file: 1) Curriculum Vitae (including a list of publications); 2) Research statement (max. 4 pages) outlining past achievements, research interests, and envisioned contributions to PRIMA; 3) PhD diploma (or an official statement confirming its expected completion date). Additionally, at least two letters of recommendation should be sent directly by the referees. Send all applications and information requests to nadege.lagarde @ u-bordeaux.fr. The review of applications will start immediately and will continue until May 31, 2025 or until the position is filled. The hiring process and the working relationship will adhere to the principles of diversity and inclusion upheld by our parent institutions.
