The European Organisation for Astronomical Research in the Southern Hemisphere (ESO) is the foremost intergovernmental astronomy organisation in Europe and the world's most productive ground-based astronomical observatory. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries.

ESO operates three unique world-class observing sites in northern Chile: La Silla, Paranal and Chajnantor (home to ALMA), and the ESO Headquarters are located in Garching, near Munich, Germany.

At Paranal, ESO operates the Very Large Telescope, the world's most advanced visible-light astronomical observatory, and will host and operate the southern array of the Cherenkov Telescope Array, the world's largest and most sensitive high energy gamma-ray observatory. ESO is a major partner in ALMA. On Cerro Armazones, ESO is building the 39-metre Extremely Large Telescope (ELT), which will become "the world's biggest eye on the sky" and whose operations will be fully integrated into the Paranal Observatory.

Within the Directorate for Science at its Headquarters in Garching, near Munich, Germany, ESO is inviting university students to apply to our ESO Summer Research Programme. The ESO Summer Research Programme is an opportunity for university students from science, technology, engineering, and mathematics (STEM) fields who have not yet started a PhD programme and have completed at least two years of their degree.

Your application is welcome if you would like to be considered for Project A: Assessing Assembly Bias Through the Satellite Populations of X-ray-Selected Halos

Applications for the ESO Summer Research Programme will be considered from students taking any astronomy, physical science, computer science or mathematical degree subjects. However, it is expected that students have some knowledge of physics, programming, data analysis techniques and, preferably, astronomy.

Students will be selected for the programme based on their academic achievements, research potential and likelihood to significantly benefit from the experience. Particular attention will be given to the motivation of the students to join the programme and specific motivation for Project A:

Project A: Assessing Assembly Bias Through the Satellite Populations of X-ray–Selected Halos

Galaxy groups and clusters are key environments for studying how galaxies evolve, because satellite galaxies in these systems experience a range of physical processes - such as gas stripping, starvation, and tidal interactions - that depend strongly on their surroundings. A useful way to characterize these environments is through their X-ray luminosity (Lx), which reflects the amount and density of hot gas in the system. Since Lx is linked not only to halo mass but also to a system's formation history and the density of the surrounding large-scale structure, it may serve as a broader indicator of environmental conditions and possible assembly bias.

This project will investigate how the properties of satellite galaxies - such as colors, star-formation activity, stellar masses, and simple morphology indicators - vary across groups and clusters with different X-ray luminosities. By combining X-ray-selected systems with optical galaxy data, and by using either observational datasets and/or cosmological simulations, the study will test whether Lx provides information about galaxy evolution that goes beyond what halo mass alone can account for.

Head of the Office for Science Garching

Students must be proficient in both spoken and written English.

Contract:

The duration of the ESO Summer Research Programme is six weeks: 15 June - 24 July 2026.

Participation in the programme will only be possible on-site at ESO in Garching, near Munich.

Travel costs to/from Garching will be offered to students of the programme. Accommodation will also be provided in a shared apartment in Garching (utilities included). Students will also be provided with a modest stipend to cover living costs for the duration of the programme.

Students that require a visa to travel/work in Germany are responsible for fulfilling the necessary requirements for obtaining a visa in good time. Successful applicants are encouraged to start the procedure as soon as they receive the offer of acceptance into the programme (approx. three months before the start of the programme). The ESO Human Resources department will also be able to provide any specifically required documents required for the visa request to the consulate/embassy.

Applicants are invited to apply online at http://jobs.eso.org/ . Applications must be completed in English and should include the following material:

• a Motivation Letter containing both motivation for the ESO Summer Research Programme and specifically for this project (max one page). Please state if you also have an interest in one of the other six projects offered within the scope of the ESO Summer Research Programme. A separate application is not required.
• a CV containing details of your highest qualification level / degree to date (for example, BSc or MSc). If you are currently enrolled in a programme which you have not yet finished, please state the university/institute and the start and expected finish dates. Please outline the programming languages you can use (and your level of proficiency), any experience using astronomical software, and any other relevant technical skills. Please also list any workshops, research schools, or conferences that you have attended with the corresponding dates and website if available.
• a Research Plan describing a research project that you have carried out in the past and the skills that you acquired (max. half page). Please include the university/institute where the research was undertaken and the start and end dates of the project. This could be a project as part of your degree programme or another research experience. Please note that if you have no previous experience, this will not negatively affect your application.
• the name and contact details of a Referee who is familiar with your academic or research achievements and can write a recommendation letter on your behalf. Once you enter their details in the online application form, they will automatically receive an invitation to submit the letter. To ensure your referee has enough time to draft and upload their letter before the application deadline, you are strongly encouraged to initiate the invitation well in advance. You have the possibility to partially complete your application, initiate the invitation to your Referee, and finalise preparing your other material at a later point in time before the deadline.

By submitting an application, you verify that:

• the information provided in your application is correct and complete to the best of your knowledge.

Deadline for applications is 31 January 2026.

Interviews are expected to be held in late March 2026, online via MS Teams.

For any enquiries related to the programme contact us via: [e-mail]
