Applications are invited for a postdoctoral research position analysing X‑ray observations of galaxy clusters with Dr Helen Russell. The successful candidate will play a lead role in the analysis of new XRISM observations of cluster cores awarded to PI Russell in Cycles 1 and 2. This position is funded by a 5‑year Leverhulme Trust award, ‘The physics underpinning feedback from supermassive black holes’, and includes generous travel funding and computing equipment.

• Lead analysis of XRISM observations of cluster cores and map dynamics of cluster atmospheres.
• Conduct X‑ray data reduction, spectral fitting and interpretation of cluster physics.
• Collaborate with theory, simulations and machine‑learning groups within the Astronomy Group.
• Publish results in high‑impact refereed journals and present at conferences.
• Assist in the development of new analysis pipelines and support junior researchers.

• Ph.D. in astrophysics, X‑ray astronomy or related area (or near completion).
• Experience with analysis of X‑ray observations, XRISM or similar missions.
• Strong computational skills and experience with data analysis software.
• Excellent written and oral communication and teamwork skills.
• Interest in supermassive black hole feedback, galaxy cluster physics or related topics.

• Flexible start date, but preferably by 1 October 2026; funded until 31 August 2029.
• Full‑time (36.25 h per week). Job‑share arrangements may be considered.
