19.09.2025 ESA Archival Research Visitor Programme 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. The next deadline…

18.09.2025 PhD position in gravitational-wave astronomy and massive binary evolution at Radboud University Join a pioneering PhD project exploring how massive stars evolve into gravitational-wave sources. Combine stellar physics, simulations and cutting-edge data to uncover the origins of black holes and neutron stars, linking theory with the latest discoveries in this rapidly growing field. This PhD position is embedded in the Astrophysics Department at the Institute for Mathematics, Astrophysics and Particle Physics (IMAPP) at Radboud University (Nijmegen, Netherlands). We are a very tight-knit and socially active department, currently home to 18 faculty members (junior and senior) and about 65 postdoctoral researchers and PhD candidates. Research at the department covers a…
