Job Announcement Text: 

Caltech is a world-renowned science and engineering institute that marshals some of the world's brightest minds and most innovative tools to address fundamental scientific questions. IPAC, part of the Physics, Math, and Astronomy Division at Caltech, provides science operations, user support, data and archive services, and scientific vision to maximize discovery with observatories both in space and on the ground.

We invite applications for a Postdoctoral Scholar position in the field of extragalactic astrophysics at Caltech/IPAC to work on the successful JWST Cycle 1 NIRISS pure-parallel slitless spectroscopy program, PASSAGE (GO1571, PI Malkan). With a total allocation time of up to 500 hours, PASSAGE represents one of the largest JWST surveys providing a rich spectroscopic dataset to study galaxy evolution from the first billion years to the present-day universe. The postdoctoral scholar will take a lead role in the data reduction and analysis of the JWST grism observations as well as conduct scientific analysis on topics pertaining to galaxy evolution from the inferred galaxy physical properties.

Furthermore, this position will be partially supported by the ESA/NASA Euclid mission, which was launched in August 2023 and is now preparing to commence survey operations. The postdoctoral scholar will engage with members of the U.S. Euclid team and European colleagues to conduct galaxy physical parameter estimation and outlier detection with the Euclid photometry via machine learning techniques that leverage empirical relations.

The postdoctoral scholar will work with Dr. Vihang Mehta and be responsible for data processing, analysis and interpretation, and publication of scientific results. The work will be conducted in collaboration with Dr. Harry Teplitz, Dr. Anahita Alavi, Dr. James Colbert, and Dr. Daniel Masters at IPAC as well as other domestic/international collaborators. In addition, you will be encouraged to spend a fraction of your time on independent research, and will have access to observing facilities, including Palomar.
