Research Associate/Fellow â XRISM observations of cluster cores (Fixed-Term) (SCI400726)

Applications are invited for a postdoctoral research position analysing X-ray observations of galaxy clusters with Dr Helen Russell at the University of Nottingham. The successful candidate will play a lead role in the analysis of new XRISM observations of cluster cores that were awarded to PI Russell in Cycles 1 and 2. Built and operated jointly by JAXA and NASA, with participation from ESA, XRISM's incredible spectral resolution now allows us to map the dynamics of cluster atmospheres. This position is funded by a 5-year Leverhulme Trust award, `The physics underpinning feedback from supermassive black holes', and therefore includes generous funding for travel to conferences and computing equipment.

Applicants with experience analysing X-ray observations and research interests in supermassive black hole or galaxy cluster physics are especially encouraged to apply. Applicants should have, or be close to completion of, a Ph.D. in astrophysics or a related subject area. Applicants should complete the online submission form and attach a copy of their CV, publications list (if not included in the CV), and a description of their research interests and relevant work to date (up to two pages).

The vacancy is funded until 31/08/2029, with a flexible start date, but preferably by 1st October 2026. Hours of work are full-time (36.25 hours per week). Job share arrangements may be considered. 

Successful candidates will join the Astronomy Group in the School of Physics & Astronomy at Nottingham. The group has a collaborative focus on extragalactic astronomy with expertise spanning observations, theory, computer simulations and machine-learning analyses.

The University of Nottingham offers a wide range of employee benefits. More information can be found at: https://www.nottingham.ac.uk/hr/your-benefits/a-z-of-benefits/benefits-a-z.aspx

As part of our commitment to improving equality, diversity, and inclusion within the school, shortlisted candidates will be given the opportunity to talk to a member of staff representing women, racially minoritized people, LGBTQIA+, or disabilities communities. This will be separate from the assessment process and will play no role in the decision to appoint.

Informal enquiries are encouraged and should be sent to Helen Russell [helen.russell@nottingham.ac.uk]. Please note that applications sent directly to this email address will not be accepted.
