Astrophysical and Cosmological Relativity Department · Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Potsdam, Germany

Gravitational-wave astronomy is moving from discovery to precision science. The Astrophysical and Cosmological Relativity (ACR) department at the Albert Einstein Institute (AEI) in Potsdam works across the full chain of that transition — from first-principles modeling of strong-field gravity, through numerical relativity, to the analysis and interpretation of data from LIGO, Virgo and KAGRA today, and from Einstein Telescope, Cosmic Explorer and LISA in the decade ahead.

We invite applications for several postdoctoral appointments, offered at different levels according to experience and seniority, with durations from two to five years. Application deadline: November 23rd 2026.

Positions

• General appointments in the ACR department, at junior and senior postdoctoral level.
• Several positions within the ERC Synergy Grant “Making Sense of the Unexpected in the Gravitational-Wave Sky”.
• One position within the Simons Collaboration on Black Holes and Strong Gravity.
• One position within the Center of Gravity, shared between the AEI (two years) and the Niels Bohr Institute in Copenhagen (two years).

The department also hosts Max Planck Fellowships for scientists from outside Germany; details and application instructions are available here.

We are looking for creative, highly motivated researchers who work equally well independently and within a large, interdisciplinary group.

The department

Led by Alessandra Buonanno, ACR comprises about 45 scientists, including three permanent research group leaders — Jonathan Gair, Harald Pfeiffer and Jan Steinhoff. The department hosts a steady flow of long- and short-term visitors and maintains close ties with the Department of Physics at the University of Maryland, Humboldt University of Berlin and the University of Potsdam.

Research areas

• Analytical modeling of gravitational dynamics and radiation: effective field theory, post-Newtonian and post-Minkowskian expansions, gravitational self-force, black-hole perturbation theory and the effective-one-body formalism.
• Numerical relativity: vacuum simulations of compact objects on bound and unbound orbits, in general relativity and in alternative theories of gravity.
• Observation and interpretation of gravitational-wave data from ground-based (LIGO, Virgo, KAGRA, Cosmic Explorer, Einstein Telescope) and space-based (LISA) detectors, including searches and detector characterization.
• Acceleration of gravitational-wave inference, including machine-learning methods.
• Astrophysics of compact objects and binary formation scenarios.
• Cosmography with gravitational waves: dark energy, dark matter and gravitational lensing.
• Tests of gravity in the strong-field and highly dynamical regime.

Collaborations

ACR participates in the Simulating eXtreme Spacetimes (SXS) Collaboration, the LIGO Scientific Collaboration, the Einstein Telescope Collaboration, the LISA Consortium, and the LISA Distributed Data Processing Centre, where the department leads waveform generation and the global-fit deep analysis.

Computing

The department operates Urania, a high-performance cluster with ~6,050 cores; Hypatia, a high-throughput cluster with ~12,000 cores; and two GPU servers, Saraswati and Lakshmi, each with eight NVIDIA A100 GPUs. Both clusters are currently being extended.

The Laboratoire d’Annecy de Physique Théorique (LAPTh) invites applications for two postdoctoral positions within ADACSI (Accelerating Discoveries in Astrophysics and Cosmology with Simulation-based Inference), funded by the Multidisciplinary Institute for Artificial Intelligence (MIAI) through an AIforScience Research Chair.

ADACSI will develop a multi-probe simulation-based framework for the joint analysis of large-scale structure (LSS) and gamma-ray data. By combining these complementary probes of the same underlying matter distribution, the project aims to sharpen constraints on astrophysical source populations and dark-matter signals, exploiting statistical correlations across datasets to break degeneracies that limit single-probe analyses. The framework will be validated on synthetic data and applied to public datasets, e.g. Fermi-LAT and DESI.

The two postdocs will be recruited simultaneously and will work as a team toward a single joint pipeline.

Position 1 — LSS forward modelling and SBI methodology. Developing fast simulations of the LSS observables, in particular data from spectroscopic galaxy surveys and CMB lensing and the inference machinery, building on and extending the SimBIG pipeline. This forward model is also the baseline for the gamma-ray side of the project.

Position 2 — Gamma-ray astrophysics and data analysis. Modelling how gamma-ray emitters populate the cosmic web and linking source populations to the underlying halo and galaxy distribution; developing SBI pipelines for Fermi-LAT data, first standalone and then jointly with LSS.

Qualifications. A PhD in astrophysics, cosmology, or a related field completed by the start date; strong programming skills; working knowledge of machine learning applied to astrophysics and cosmology, in particular simulation-based inference. For Position 1, experience with LSS simulations and analysis, and ideally galaxy redshift surveys and HPC. For Position 2, experience with gamma-ray data analysis and its astrophysical interpretation. Applicants with a strong machine-learning or statistics background moving into astrophysics are welcome.

Supervision and environment. Both positions will be co-supervised by Dr. Azadeh Moradinezhad and Dr. Francesca Calore, within the Astroparticle and Cosmology group at LAPTh (astrocosmolapth.com). External collaborators include Christoph Weniger (GRAPPA, University of Amsterdam) and Francisco Villaescusa-Navarro (Flatiron Institute, New York), as well as SimBIG collaboration. A PhD student and several Master’s students will also be recruited within ADACSI, offering co-supervision opportunities. The positions provide access to CNRS/LAPTh computing resources and generous travel support and, as an MIAI-funded chair, connect the postdocs to the institute’s interdisciplinary AI community; the group also benefits from its proximity to the University of Geneva and CERN.

Terms. Position 1 is a two-year appointment; Position 2 is a three-year appointment. Salary on the USMB scale, commensurate with experience, including social security and health coverage. The expected start date is 1st October 2027with some flexibility.

Applications. Submit via AcademicJobsOnline:

1. a cover letter, indicating Position 1, Position 2, or both;
2. a CV with a list of publications;
3. a research statement (up to four pages);
4. three letters of recommendation, arranged by the applicant.

Applications received before November 20th – 2026 will receive full consideration; the positions remain open until filled. Shortlisted candidates will be invited to a remote interview.

Interested individuals are encouraged to upload all material before November 15th, 2026. The search will remain open until finished.

We seek international outstanding individuals eager to join an ambitious research program addressing the exploration of black holes as engines of discovery. This call is seeking specifically outstanding candidates to study the effect of environments in gravitational wave physics and data analysis strategies to robustly identify these in future events. However, outstanding individuals in complementary fields are also warmly welcomed to upload their material.

We are also looking for a candidate to join the GWSkyproject. This project, funded by an ERC Synergy Grant, aims to use gravitational-wave measurements by existing and future observatories on the Earth and in space as precision laboratories for fundamental physics, cosmology, and astrophysics. The GWSky project aims to develop a groundbreaking framework capable of solving the highly nonlinear equations of Einstein’s General theory of Relativity, creating waveform models with unprecedented accuracy, and translating these results into practical tools for interpreting the data. For the GWSky position we are primarily looking for candidates in the field of Gravitational Self-Force and its applications to gravitational waveform modelling. While previous experience in this field is desirable, expressions of interest from excellent candidates with relevant related expertise will be considered.

This search is part of a vigorous expansion at the Niels Bohr Institute into the field of Gravitational Physics, bringing together several scientists from several areas of theoretical physics and astrophysics, and addressing some of the most burning questions related to gravity.

The Center of Gravity (CoG) is a center for new ideas about the foundations of physics. We bring together cutting-edge research in observations of black holes and in the formal theory of relativistic and quantum aspects of gravity, completing the visions of Bohr and Einstein for the gravitational interaction. Our research endeavor spans from data analysis to theoretical disciplines within astrophysics and high-energy physics, and we aim to drive gravitational-wave physics to an exciting future. We have our physical home in the beautiful and legendary building at Blegdamsvej 17, established by Niels Bohr. This is the place where quantum theory was born and where many exciting new developments in gravity are now taking place. Today, the Niels Bohr Institute carries an important legacy in physics and is one of the leading institutes in theoretical and experimental physics. At the Center of Gravity, we hope to carry on the pioneering spirit that has defined our predecessors at the Niels Bohr Institute through trailblazing and fundamental research.
