20.11.2025 Foundation Models in Astrophysics and Particle Physics (SciFM) in Aachen, Heidelberg, Hamburg and Munich We seek four postdoctoral research scientists and eight doctoral researchers to join a newly established joint collaborative project Foundation Models in Astrophysics and Particle Physics (SciFM) funded by the Federal Ministry of Research, Technology and Space (BMFTR). The goal of SciFM is to develop large-scale foundation models, aiming for powerful, interpretable and open-access models to answer fundamental scientific questions in astrophysics, particle physics and cosmology. We offer an exciting multidisciplinary collaborative network which includes researchers from astrophysics, cosmology and particle physics in Aachen, Heidelberg, Hamburg and Munich. The selected candidates will work closely with all…

20.11.2025 PhD Studentships at the University of Edinburgh The Institute for Astronomy (IfA) is located at the historic and beautiful Royal Observatory Edinburgh on Blackford Hill and makes up approximately one third of the School of Physics and Astronomy at the University of Edinburgh. PhD stipends are tax-free, and full-time students are typically exempt from council tax. Each year, the IfA admits a new cohort of about 10 PhD students from around the UK and the world. We are now accepting applications for admission in September 2026. Application deadlines from December 5th 2025 to January 5th 2026. Read more

20.11.2025 Two PhD Opportunities: Stellar Explosions and Asteroseismology in Binary Systems at KU Leuven Two PhD positions to join the new research team StarHearts of Prof. Eva Laplace at the Institute of Astronomy, KU Leuven, Belgium. When stars end their lives, their hearts continue to exist in a different, exotic form, known as a compact remnant: black holes, neutron stars, or white dwarfs. Understanding the exact origin of these objects is one of the most pressing scientific questions in astrophysics at this time. With the discovery of gravitational waves (GWs), we have a new way to study these extreme objects. To make breakthroughs in understanding the properties of stellar remnants…

20.11.2025 Postdoctoral positions at the University of Barcelona on Holographic Applications to Gravitational Waves Several postdoctoral positions funded by Prof David Mateos’ Advanced ERC Grant are now open at the Institute of Cosmos Sciences at the University of Barcelona (ICCUB). Selected candidates are expected to work with Profs David Mateos, Jorge Casalderrey-Solana and other members of the group on applications of Holography to Cosmology and Astrophysics, with a focus on Gravitational Waves. Topics of interest include cosmological phase transitions, baryogenesis, neutron star mergers, spacetime singularities and holography with dynamical boundary gravity. Application deadline: December 17th 2025. Read more

20.11.2025 2-year PostDoctoral Fellowship in theoretical physics at INFN Cagliari INFN is seeking candidates with broad expertise in gravitational waves, black hole perturbation theory, and/or cosmology. Potential research lines span from characterizing the quasi-normal mode spectrum of black holes to cosmological inference with gravitational waves (GWs) in synergy with multiple astrophysical probes. The gravitational theory group includes three staff members: Mariano Cadoni, Leonardo Modesto, and Riccardo Murgia, plus several graduate and undergraduate students. The successful candidate will be working within the Sardinian Gravitational Wave Science (SGWS) Community, in tight collaboration with the GW data analysis group at INFN and Cagliari University, and the GW group at GSSI L’Aquila. Application by…

20.11.2025 Simons Postdoctoral Fellowship at Montana State University Montana State University invites applications for a Simons Postdoctoral Fellowship position in Strong Gravity and Black Holes. The successful candidate will join a global network of Simons Postdoctoral Fellows in Strong Gravity and Black Holes that are part of the Simons-BHSG. This new, multidisciplinary and multinational collaboration explores the non-linear and dynamical nature of strong gravity and black holes in and beyond Albert Einstein’s theory of general relativity through gravitational observations. The collaboration brings together mathematicians, physicists, numerical experts and data analysts. Screening of applicants begins December 15, 2025. Read more

12.11.2025 Postdoctoral position in Gravitational-Wave Physics at Imperial College London Applications are invited for a Research Associate position in the Abdus Salam Centre for Theoretical Physics at Imperial College London. The successful candidate will work with Dr Andrea Mitridate on projects at the interface between gravitational-wave searches –with an emphasis on pulsar timing arrays observations– and physics beyond the Standard Model. Application deadline: December 5th 2025. Read more

12.11.2025 Postdoctoral position in theoretical cosmology and Gravitation at APC Paris 2-year postdoctoral position in theoretical cosmology and gravitation, starting in September 2026. The position is funded by the HERMES project, devoted to multi-messengers of the Earth and the Universe. More specifically, the aim of the research project is to explore theories of modified gravity on cosmological scales and identify how existing or future probes, using electromagnetic or gravitational wave signals, will be able to constrain these models. In this perspective, the postdoctoral researcher will be part of the theory team, but will also be expected to engage into collaborative work with the gravitation and/or the cosmology teams at APC.…
