The RING project in Germany: 1 Postdoc and 14 PhD positions in Physics, Geophysics, Geodesy

we would like to draw your attention to the 4-year RING project recently funded by the German Research Foundation (extendable to 8 years). The project has strong overlap with gravitational wave detection research on instrumentation.

The project aims at pushing the sensitivity and stability limits of rotational motion sensing with ring laser technology into new realms using approaches from quantum optics and metrology. The ultimate goal is to enable ring laser observations as a complement to classic space-geodetic methods towards more precise, high-rate estimation of Earth Orientation Parameters (EOP). Furthermore, we plan to develop (trans-) portable ring lasers fit for weak, broadband 6 degree-of-freedom ground motion observations towards better understanding of atmosphere-solid Earth coupling (also relevant for seismic decoupling of gravitational wave detection facilities).

The project offers postdoctoral and PhD topics in laser physics, geodesy, geophysics, hydrology, and seismology. The successful candidates will be part of a multi-disciplinary research team at various institutions in Germany with excellent training and experimental facilities.

PhD Scholarships – Statistics, Astrophysics, Cosmology and Gravitational Wave Astronomy in New Zealand

The NZ Astrostatistics and General Relativity Group (NZ Gravity) is coordinating applications for several PhD scholarships within an interdisciplinary team to work on 
• interstellar objects, stellar populations, supernovae, large scale structure formation and ultralight dark matter, engaging with the Vera Rubin Observatory Legacy Survey of Space and Time (LSST) and
• gravitational wave astronomy and statistical data analysis for the Laser Interferometer Space Antenna (LISA) mission.

The cross-institutional research team spans astrophysics, cosmology, mathematics and statistics with members at five New Zealand universities as well as international collaborators within the Vera Rubin Observatory and the International LISA Consortium.

The LSST is a ten-year, wide-field astronomical survey designed to image the entire southern sky every few nights using a 3.2 gigapixel camera, creating a massive 200-petabyte dataset for studying dark energy and dark matter, mapping the Milky Way, exploring the transient optical sky, and identifying potentially hazardous near-Earth asteroids. The space-based gravitational wave mission LISA raises deep challenges regarding source modelling and numerical simulation and requires new statistical methodologies. We are seeking highly motivated and skilled students with a strong background in statistics, physics, mathematics or a related discipline, with sound computing skills and a keen interest in interdisciplinary research in gravitational wave science. All PhD and MSc candidates will have the opportunity to join the NZ Gravity Group, obtain academic support from an interdisciplinary supervisory team and will contribute to cutting-edge research for the LSST and the LISA mission. The PhD scholarships will be available from May 2026 and provide an annual (tax-free) stipend of NZ$35,000 plus tuition fees for three years. Starting dates are flexible throughout the year.

ESA Archival Research Visitor Programme Madrid, Noordwijk

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 (the data must be publicly available in the archives). 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 Wednesday 30 April 2026, 23:59 UTC

Call for applications

Applications can be submitted at any time by sending email to arvp@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 2 pages for the text of the proposal, max 1 page for figures, references, and contact information) 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 two pages for the text and one page for figures, references, and contact information. You must indicate in which year you obtained (or will obtain) 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@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

ERC-funded Postdoc and PhD positions on gravitational-wave theory, source modeling, and science interpretation at the MPI 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 Science Park announces the opening of several Ph.D. students and postdoctoral appointments in gravitational-wave theory, source modeling, and science interpretation. Successful candidates will join the GWSky project, which an ERC Synergy Grant  has recently funded. We are particularly interested in hiring creative and highly motivated candidates who can work collaboratively and independently in a vibrant, welcoming, and synergistic group. The deadline for full consideration is December 6, 2024.

The ERC-funded project called “Making sense of the unexpected in the gravitational-wave sky (GWSky)” is led by PIs Alessandra Buonanno, head of the ACR department, Enrico Barausse (SISSA, Trieste, Italy), Zvi Bern (University of California, Los Angeles, US), and Maarten van de Meent (Niels Bohr Institute, Copenhagen, Denmark). Given the synergistic aspect of the GWSky project, we anticipate that for a few postdoctoral scholars, there will be the opportunity to spend two years at the AEI and the subsequent two years in another node. One of the supervisors of the Ph.D. students at the AEI may be located in another node.

The aim of the GWSky project is 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. This includes the current LIGO-Virgo-KAGRA detectors, as well as the future ground-based observatories Cosmic Explorer and Einstein Telescope, and the space-based detector LISA. By leveraging the PIs and their groups’ expertise, the GWSky project aims to develop a groundbreaking framework capable of solving the highly nonlinear equations by Einstein’s General theory of Relativity, creating waveform models with unprecedented accuracy, and translating these results into practical tools for interpreting the data.

As a consequence, we are looking at candidates in the following research areas: post-Minkowskian formalism, scattering amplitudes, gravitational self-force, post-Newtonian theory, effective-one-body formalism, numerical-relativity surrogate models, methods to accelerate waveform generation, numerical-relativity simulations in General Relativity and alternative theories of gravity, environmental effects for binary systems, tests of General Relativity, gravitational-wave data analysis and machine learning.

To apply, please submit your application via our job portal
for the postdoctoral positions here.
for the PhD positions here.

You will be asked to upload a cover letter, curriculum vitae, list of publications and a statement of past and future research activities of not more than 3 pages.
