2023 Fiscal Year Research-status Report

• Project/Area Number: 23K13150
• Research Institution: National Astronomical Observatory of Japan
• Principal Investigator: Zavala Jorge 国立天文台, アルマプロジェクト, 特任助教 (80933150)

• Keywords: Galaxies / Galaxy formation / Star-forming galaxies / Early universe / Galaxy evolution

Outline of Annual Research Achievements

The researcher conducted various research activities that resulted in the acceptance of several observational proposals for telescopes such as ALMA and JWST. The first of these programs led to the confirmation of one of the most distant known galaxies at a redshift of 12.3. These findings have been submitted for publication and are currently under review in a reputable scientific journal.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

The JWST data from the accepted proposal was executed and delivered on time. This allowed for the recent submission of a scientific publication. However, the ALMA data was not completed on time, which slightly affected (but not critically) the progress of the project. These astronomical observations are expected to be conducted in the next two semesters, allowing a smooth continuation of the project.

Strategy for Future Research Activity

During FY2024, the researcher will focus on the analysis of the ALMA data. The results of this project are expected to be published by the end of FY2024. During FY2025, the researcher will focus on the combination of the JWST and ALMA data that will become available by the end of FY2024. This will allow the preparation of a third scientific publication during FY2025 and FY2026.
