Postdoctoral Research Associate ; Cosmology, Extragalactic Astronomy

Position Highlights

The University of Arizona (UA) Department of Astronomy and Steward Observatory (SO) invite applications for a Postdoctoral Research Associate who will play a leading role in the newly initiated Subaru Hyper Suprime-Cam (HSC) medium-band (MB) survey. The HSC/MB filters cover the 400–1000 nm range with 16 bands (R ~ 20), and will be used to conduct a large 3-tier survey (wide/deep/ultradeep) over the next several years.

This large international collaboration, including the Euclid and DESI2 teams, is headed by a group in Japan, and UA/SO is a major partner providing the four reddest MB filters.

The successful candidate will work with Dr. Eiichi Egami and is expected to make major contributions to all aspects of the survey. Technical experience/expertise in developing an imaging data-processing pipeline would be highly desirable. We are especially interested in candidates working in the fields of cosmology and/or high-redshift galaxies who can design and lead exciting science programs in collaboration with the survey team members at UA/SO (Behroozi, Eifler, Fan, Krause, Rozo) and NOIRLab (Dey).

This position is a year-to-year appointment, expected to last for two years initially with the possibility of renewal for a third year. Candidates must have completed all requirements for a PhD before the commencement of the position. The HSC/MB survey is currently expected to start in Spring 2026, so special consideration will be given to those candidates who can start early in 2026.

• Planning and execution of the observations.
• Development of the data processing/analysis pipelines.
• Follow-up observations using ground/space telescopes.
• Publication of scientific results.

• Design and lead exciting science programs in collaboration with the survey team members at UA/SO (Behroozi, Eifler, Fan, Krause, Rozo) and NOIRLab (Dey).
• Supervise/mentor graduate and undergraduate students.
• Take part in outreach activities as needed.

• Must have completed all the requirements for a PhD in Astronomy, Physics, Astrophysics, or related science at the time of hire.

• Candidates with a PhD in Astronomy/Astrophysics or Physics are preferred.
• Research experience relevant to one or more of the following scientific areas: cosmology, high‑redshift galaxies.
