29.04.2026 Research Associate for the Project “Cluster of Excellence Quantum Universe” Project “MADMAX” Duties include academic services in the project named above. Research associates may also pursue independent research and further academic qualifications. The Cluster of Excellence “Quantum Universe” performs research to understand mass and gravity at the interface between quantum physics and cosmology. The research team includes leading scientists from mathematics, particle physics, astrophysics, and cosmology at the University of Hamburg and DESY. The Axion is a prime candidate to explain the Dark Matter problem of the universe. It is independently predicted by Peccei Quinn (PQ) symmetry breaking to explain the strong CP problem. Application deadline: May 7th, 2026.…

28.04.2026 GSSI PhD in Astroparticle Physics 2026 The Physics Division of the GSSI – Gran Sasso Science Institute (L’Aquila, Italy) is opening 10 PhD positions in Astroparticle Physics, starting in the Academic Year 2026/2027. Two additional PhD positions are offered through the FIS project Deep Loop Shaping for Gravitational-wave Detection, and another position through the AstroCent+ project on dark-matter searches with DarkSide-20k. The research pursued by the Physics Division focuses on neutrinos, gravitational waves, dark matter detection, and cosmic rays. The Gravitational-Wave Group is active in the LVK, ET, LGWA, and LISA collaborations. Its research activities are in instrument science, data analysis, waveform and population modelling, multi-messenger and transient astrophysics,…
