Two postdoc positions in the Nikhef Gravitational Wave Group

Nikhef is the national institute for subatomic physics in the Netherlands. At Nikhef, approximately 250 physicists and 80 technical staff work together in an open and international scientific environment. Together they perform theoretical and experimental research in the fields of particle and astroparticle physics. Nikhef is a partnership between six major Dutch universities and NWO-I Foundation, the Institutes Organization of the Dutch Research Council (NWO).

Nikhef participates in a wide range of research collaborations, including the ALICE, ATLAS and LHCb experiments at CERN, the KM3NeT neutrino telescope in the Mediterranean, the Virgo gravitational waves interferometer in Pisa, the Xenon-nT dark matter experiment in Gran Sasso, the Pierre Auger cosmic ray observatory in Argentina, and the eEDM research programme in Groningen. Nikhef furthermore has scientific groups on theoretical particle physics, physics data processing, and detector R&D, and has excellently equipped technical departments in mechanics, electronics, and computing. Nikhef is preparing to take a leading position in the future Einstein Telescope.

The group and the Einstein Telescope

The Gravitational Wave group consists of about 20 staff scientists, 20 postdoctoral researchers, and 30 PhD candidates. The group is engaged in gravitational-wave observational science through active participation in the LIGO and VIRGO interferometer collaborations, and in instrumentation R&D with a particular emphasis on components for the VIRGO detector, such as advanced seismic isolation and suspension systems.

Nikhef has established ETpathfinder, a dedicated R&D infrastructure located in Maastricht, aimed at developing and testing key technologies to enable the low-frequency sensitivity of third-generation detectors like the Einstein Telescope (ET).

The group also plays a central role in the preparatory efforts for the Einstein Telescope. The Netherlands, in collaboration with Belgium and Germany, is coordinating a transnational initiative to propose the EMR (Euregio Meuse-Rhine) region as a candidate site for the ET. Over the coming years, detailed site characterization and environmental studies will be conducted to assess the EMR’s viability, which will be a decisive factor in the final site selection process for the observatory.

The positions

The postdoctoral researchers will focus on advancing the detailed understanding of site-specific noise sources in the geology of the EMR region, and their impact on the Einstein Telescope. This includes the characterization of seismic activity, electromagnetic disturbances, and the modeling and prediction of Newtonian Noise that impacts the detector’s low-frequency performance. A key aspect of the research will be the development of noise mitigation tools.

The successful candidates will have a strong background in mathematical and computational methods, with demonstrated experience in the data analysis of complex physical systems. You will collaborate with a team of experts at Nikhef, as the position is embedded within the Gravitational Wave Group. This team provides a collaborative and multidisciplinary research environment covering all aspects of gravitational wave research. The deadline for applications is September 5, 2025.

Offer

The candidates will be employed by the NWO-I foundation for a period of 2 years. You will be embedded in the Nikhef Gravitational Wave group and stationed either in Amsterdam or Maastricht. The salary is competitive, and the conditions of employment (https://www.nwo-i.nl/en/employees/) are excellent.

Requirements
A background in computational methods is required. Applicants should have a PhD in physics or mathematics (or a closely related topic) by the time they start their appointment at Nikhef.

Further information and application
Qualified applicants are encouraged to apply by clicking the ‘apply now’ button below. Please be prepared to upload a curriculum vitae and a motivation letter, and have the email addresses of at least two referents ready, who are willing to send a letter of recommendation on your behalf. The deadline for applications is September 5, 2025. For further information, feel free to contact Stefan Hild.

Nikhef is committed to being an inclusive and diverse organisation. Applications from women and people belonging to minority and underrepresented groups are especially welcomed.

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/).
