Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure? No Offer Description Background of the recruitment and description of the project The National Astronomical Observatory of Japan (NAOJ) has the JASMINE Project aiming to develop the science payload and the mission operation system of the JAXA (Japan Aerospace Exploration Agency)’s infrared space astrometry mission, JASMINE. JASMINE will conduct high-precision infrared astrometry toward the central region of the Milky Way to study its formation and evolution, and will also carry out time-domain observations for the exploration of potentially habitable exoplanets. JASMINE completed the Mission Definition Review (MDR) at the JAXA Institute of Space and Astronautical Science (ISAS) in July 2024 and is currently advancing technical studies and organizational preparations toward the next phase of the mission. JASMINE will repeatedly observe stars over the mission period and produce an astrometric catalog for more than 100,000 stars. To achieve the required astrometric precision, the mission must establish, before launch, analysis methods and infrastructure that use large-scale observation simulations to evaluate performance, calibrate systematic effects, and derive astrometric parameters. The JASMINE Project therefore develops the instrument, observation strategy, and data analysis system in close coordination so that the required precision is achieved by the mission system as a whole. Work content and job description We invite applications for an assistant professor position at the JASMINE Project of NAOJ. A successful candidate for this position is expected: to lead the development of analysis methods to derive astrometric parameters from JASMINE observational data, including verification using mission-scale simulations and relevant observational data; to make a significant contribution to the design and construction of the data analysis infrastructure required for JASMINE, including adaptation to emerging computational technologies and environments; to make a significant contribution to the operation of JASMINE astrometric data analysis and to the public release of the JASMINE astrometric catalog; to collaborate with other NAOJ projects and centers to advance JASMINE data analysis, while also contributing to the development of astronomical big data analysis; to foster early career scientists and graduate students at NAOJ and to collaborate with them through activities related to the JASMINE mission and its broader scientific applications.
