Postdoctoral positions in Gravitational-Wave Physics and Astrophysics at the Max Planck Institute for Gravitational Physics in Potsdam

The "Astrophysical and Cosmological Relativity" (ACR) department at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in Potsdam announces the opening of several postdoctoral appointments, which will be available at different levels, depending on experience and seniority, and can last from 2 to 5 years. We also have openings as part of the ERC-Synergy Grant  “Making Sense of the Unexpected in the Gravitational-Wave Sky”, one opening as part of the Simons Collaboration on Black Holes and Strong Gravity, and one opening for a postdoctoral position as part of the Center of Gravity. For the latter, the successful candidate will spend the first two years at the AEI and the subsequent two years at the Niels Bohr Institute in Copenhagen. The ACR department also offers Max Planck Fellowships to non-German scientists. Information on those fellowships and explanations on how to apply are summarized here. We are particularly interested in hiring creative and highly motivated candidates who are at ease working both collaboratively and independently in a vibrant, interdisciplinary, and synergistic group.

The ACR department, led by Alessandra Buonanno, is composed of about 45 scientists, including three permanent research group leaders, Jonathan Gair, Harald Pfeiffer and Jan Steinhoff, and the five-year research group leader Miguel Zumalacarregui. The department also hosts several long and short-term visitors, and has ties with the Physics Department at the University of Maryland, the Humboldt University in Berlin, and the University of Potsdam.

The ACR department is interested in  many aspects of gravitational-wave astronomy, including (i) analytical modeling of gravitational dynamics and radiation (effective field theory, post-Newtonian and post-Minkowskian expansions, gravitational self-force approach, perturbation theory and effective-one-body formalism), (ii) numerical relativity, most notably simulations in vacuum of compact objects on bound and unbound orbits in general relativity and alternative gravity theories, (iii) observation (including searches and detector characterization) and interpretation of data from gravitational-wave detectors on the ground (LIGO, Virgo, KAGRA, Cosmic Explorer, Einstein Telescope) and in space (LISA), (iv)  techniques for the acceleration of gravitational-wave inference, including machine learning, (v) astrophysics of compact objects and bi-nary’s formation scenarios, (vi) cosmography with gravitational waves (including dark energy, dark matter, gravitational lensing), and (vii) tests of gravity in the strong-field and highly dynamical regimes.

The ACR department participates in many international collaborations: the Simulating extreme Spacetimes Collaboration (SXS), the LIGO Scientific Collaboration (LSC),  the Einstein Telescope (ET) Collaboration, the LISA Consortium, and the LISA Distributed Data Processing Centre (DDPC), where our department plays a leading role in waveform generation and the global fit deep analysis.

Currently, the ACR department operates a high-performance compute cluster, Urania, with ~6,050 cores, a high-throughput compute cluster, Hypatia, with ~12,000 cores, and two servers, Saraswati and Lakshmi, each with 8 A100 GPUs. Those clusters are in the process of being extended. They are used to run numerical-relativity simulations of gravitational-wave sources, and to carry out source modeling and data-analysis studies for current and future gravitational-wave detectors.

ESA Archival Research Visitor Programme

To increase the scientific return from its space science missions, ESA welcomes applications from scientists interested in pursuing research based on publicly available data in the ESA Space Science Archives. The Archives host data from all current and past ESA space science missions in astronomy, planetary science, and heliophysics.

The ESA Archival Research Visitor Programme is open to scientists at all career levels who are affiliated with institutes in ESA Member States and Cooperating States (note that all visits must comply with the ESA Security Directives, which may necessitate additional checks). Early-career scientists are particularly encouraged to apply, including PhD students (see below). We encourage applications from women and minorities. The peer-review evaluation process is anonymised to ensure equal opportunities for all applicants.

Residence lasts typically between one and three months, also distributed over multiple visits, depending on the complexity of the research project. The research projects can be carried out at ESAC (Madrid, Spain) and at ESTEC (Noordwijk, Netherlands). To offset the expenses incurred by visitors, ESA covers travel costs from and to the home institution and provides support for lodging expenses and meals.

During their stay, visiting scientists have the opportunity to interact with archive and mission specialists for questions on the retrieval, calibration, and analysis of archival data. In principle, all areas of space research covered by ESA science missions can be supported. To ensure that technical expertise in the specific area of interest is available at ESAC or ESTEC, applicants should consult the table of expertise and contact the relevant scientists in their field of interest (this is very important). In case of doubts, write to the programme coordinators for assistance at arvp@cosmos.esa.int.

The next deadline for applications is Monday 10 November 2025, 23:59 UTC

Call for applications

Applications can be submitted at any time by sending email to arvp(at)cosmos.esa.int. The email should contain a single PDF document of at most three pages detailing:

  • description of the goals of the research project
  • public archival data on which help is sought
  • which type of expertise you expect to gain
  • proposed time and duration of the visit
  • expected publications
  • contact information

Please keep it short (max 3 pages) and follow the simple template provided here. Note that this is just a template, you can use the font type and size that you prefer (not smaller than 10), but please do not exceed three pages. You must indicate the (expected) year of your PhD.

To prevent unconscious biases, your name, email address, and other contact information (on the third page) will not be visible to reviewers. To help in the process, you must write your application in an “anonymous” way, i.e. do not identify yourself in the text. For instance, do not mention the name of your institute or collaborators in the scientific description of the project (page 1 and 2) and when you are referring to one of your papers, do not write “I have shown that … (Author Name, 2023, Journal, 954, 125)”, but rather write “It has been shown that … (Author Name, 2023, Journal, 954, 125)”. If you identify yourself, the application will not be considered.

We encourage you to contact us if you have any questions about the data that could support your research project. You will find the names of our experts in the various science areas in the table of expertise below. Or write to the programme coordinators for assistance at arvp(at)cosmos.esa.int.

Students

We welcome proposals by graduate students. The proposals can be submitted by the students themselves or in collaboration with their supervisors. If you are a student and would like to visit ESA to learn more about doing science with archival data, make sure that you coordinate and agree your research project with your supervisor. Mention this in the application, but omit the name of the supervisor, otherwise the application is not anonymous.

Deadlines

Applications can be submitted at any time and are reviewed twice a year, with deadlines usually on 30 April and 31 October. The results of the review will be communicated to applicants within about two months of the deadlines. Applicants are encouraged to contact the ESA scientists or the programme coordinators well ahead of the deadlines in order to discuss their research plans.

Applications received by 10 November 2025 (23:59 UTC) will be considered for visits in spring and summer 2026.

CDD researcher (M/F) : Ultra-dense matter equation of state and gravitational Waves, Caen, France

The determination of the equation of state and composition of ultra-dense matter from multi-messenger astrophysical observations remains a central challenge in nuclear physics and high-energy astrophysics. Within this context, the LuTH-Caen theory group, as part of the Virgo collaboration, itself part of the LIGO-Virgo-KAGRA consortium, has established a recognized expertise in the theoretical modeling of ultra-dense stellar matter and the development of advanced statistical methods for quantifying theoretical uncertainties and their impact on the confidence intervals of astronomical observables.

Application Deadline: March 27th 2025

This postdoctoral project aims to generate quantitative predictions for the key parameters governing the emission of detectable gravitational wave signals from compact objects, incorporating the uncertainties inherent in the underlying microphysics. Specifically, the successful candidate will focus on parameter estimation in one of two contexts: neutron star binary coalescence, either during the inspiral or post-merger phase, or the continuous gravitational waves emitted by isolated neutron stars.
Within this framework, the successful candidate will contribute to the interpretation of signals from past and ongoing LVK observational campaigns, as well as to the preparation for third-generation interferometers, including post-O5 and the Einstein Telescope. The research will specifically aim to constrain the microscopic properties of dense hadronic matter, such as the nuclear equation of state, and to identify potential signatures of deconfinement phase transitions.

Activities

The successful postdoctoral fellow will be responsible for maintaining and further developing the Bayesian analysis tools for equation-of-state inference within the LPC theory group. This work will be carried out in close collaboration with group members from GANIL and the Strasbourg Observatory, the latter being conducting numerical relativity simulations of post-merger remnants. Depending on the candidate’s previous research experience and interests, there may also be opportunities to contribute to the group’s theoretical developments related to the modeling of dense and superfluid matter in neutron stars. The candidate is expected to contribute to research activities and topics such as:

  • Development of the CUTER tool for the improvement of parameter estimation using microphysics informed equations of state, see https://zenodo.org/records/10781539
  • Numerical simulations for the physics case prospects of third generation interferometers
  • Theoretical modelling of the zero and finite temperature nuclear equation of state and its possible phase transitions, with both effective and microscopic models
  • Development and analysis of neutron star cooling simulations and applications to the measurable properties of the neutron star crust

Skills

The successful candidate must have a PhD in theoretical nuclear physics, gravitational wave data analysis or numerical hydrodynamics. Proficiency in scientific programming (C, C++, Python) and numerical simulations is expected. Familiarity with software development tools such as git and gitlab, while not essential, would be an advantage.

Work Context

The successful candidate will be assigned to the theory and phenomenology team, within the Corpuscular Physics Laboratory of Caen.
The team has a longstanding experience in theoretical nuclear modelling. Since 2020, it is part of the Virgo collaboration within a theoretical group including researchers from the astronomical observatory in Strasbourg, and the GANIL laboratory in Caen.
The LPC CAEN, with about 100 staff, is a joint research unit (UMR 6534) under the supervision of three institutions: the CNRS, the University of Caen Normandy (UCN) and the Ecole Nationale Supérieure d’Ingénieurs de Caen (ENSICAEN). It is located on Campus 2 of the University of Caen (Campus Côte de Nacre) and is part of the research park of ENSICAEN (www.lpc-caen.in2p3.fr/).
