Lancaster University 
Lancaster, United Kingdom Descrição do projeto
Lancaster University's School of Physics and Astronomy seeks to appoint a Postdoctoral Research Associate in Supernova Cosmology. The successful candidate will work with Dr Mathew Smith on an STFC-funded project to build an independent, homogeneous, low-redshift sample of SNeIa from the Zwicky Transient Facility (ZTF), and combine it with measurements at high redshift (e.g. from the Dark Energy Survey, the Vera Rubin Observatory’s Legacy Survey of Space and Time (LSST)) to measure the equation-of-state of dark energy.
The work will primarily focus on two closely related areas: developing a simulation and cosmological inference framework for the ZTF survey; and measuring and modelling environmental biases, including how these interact with the survey's selection effects. The output of this project will be a low-redshift anchor suitable for use by the Vera Rubin/LSST and 4MOST-TiDES surveys.
Candidates with experience in supernova cosmology are encouraged to apply. The post is available immediately, with an anticipated start date of 1st January 2027 (a later start, up to early Spring 2027, can be accommodated). The appointment is a fixed-term contract until September 2029.
In addition to joining the ZTF Collaboration, the selected candidate will join the wider Observational Astrophysics group at Lancaster, a friendly and collaborative research environment. The candidate will be welcome to participate in group research activities, which cover diverse topics including transients, high-redshift galaxies, galaxy evolution, gravitational waves and citizen science projects, and will have regular opportunities to exchange ideas across these areas.
If you have any queries regarding this position, please contact Mathew Smith at mat.smith@lancaster.ac.uk.
Qualifications:
A PhD (or near completion) in astrophysics, physics, cosmology or a related field; strong scientific programming skills (Python); research experience in supernova cosmology, statistical or systematic-uncertainty analysis, or large-scale survey science. Excellent communication and teamwork skills.
Application Requirements: CV, publication list, and a 2-page research statement describing past research experience and its relevance to the project's science goals.
Deadline: Applications received by Friday 6th November 2026, midnight UK time will receive full consideration.
Compensation: Salary commensurate with a standard postdoctoral researcher role at Lancaster.
Application instructions: Applications must be submitted through the Lancaster University online portal.
