The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly‑talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA‑affiliated research institute. These one‑ to three‑year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

The X‑ray Imaging and Spectroscopy Mission (XRISM) is a JAXA/NASA collaborative mission with ESA participation, expected to launch in the fall of 2022. XRISM is capable of high‑resolution, non‑dispersive X‑ray spectroscopy over a 3′ square field of view, as well as imaging over a much larger 40′ square field of view. Four categories of science objectives have been defined for the mission: (1) Structure formation of the Universe and evolution of clusters of galaxies;

(2) Circulation history of baryonic matter in the Universe; (3) Transport and circulation of energy in the Universe; (4) New science with unprecedented high resolution X‑ray spectroscopy. XRISM will observe virtually all classes of celestial objects, including clusters of galaxies, active galactic nuclei, X‑ray binaries, supernova remnants, hot stars, and many others. The successful applicant will carry out a research program in any area related to the science of XRISM.

This can include, but is not limited to: theoretical studies of celestial sources observable with XRISM, simulations of potential XRISM observations, relevant laboratory astrophysics, development of spectral models or atomic codes, or exploring synergies between XRISM and other contemporaneous observatories.
