Abstract
One of the main goals of the JASMINE astro-photometric satellite is to measure precise proper motions and parallaxes for hundreds of thousands of stars in the direction of the Galactic centre. To observe these distant and dimmed stars at the required level of precision, we need to pioneer in the use of infrared astrometric detectors from space, and thus extensive testing is needed to understand the instrument and model all possible biases accurately. Here we present the largest mock catalogue of the Galactic centre in the near infrared, resulting from the smart combination of observed real stars and kinematic models of the Milky Way. This catalogue, as well as the methods used to create it, will be crucial for any future survey of this region like JASMINE, ROMAN, or even Gaia NIR.

Born and raised in Barcelona, I studied Industrial Engineering at University. Already then, I felt an attraction towards research and started collaborating with professors as soon as third year. By the end of my 5-year bachelor —which I finished at the Nagaoka University of Technology— I had already contributed to a publication on microchip power supply lines. After working on the private sector for a couple years, I joined a master course on Astrophysics and Instrumentation which lead me to purse a Ph.D. in Astronomy. For 3 years, I worked with the Gaia team in Barcelona deepening our understanding of Milky Way dynamics, using the revolutionary Gaia data that I helped to validate. During that time, I also joined the WEAVE survey team and helped build its selection function. After that, I did a postdoc at the Strasbourg Observatory, continuing to work on the validation and scientific exploitation of the Gaia data. And in 2022, I moved to Tokyo to become a member of the JASMINE team.
