★First workshop
Dates: June 2, 3, and 4, 2026
Data/instruments to be covered: NIRCam/MIRI coronagraphy, MIRI/MRS (circumstellar disk)
A hands-on session for environment setup will be held on Tuesday, June 2.
Please note that, separate from this first workshop, we are planning a second workshop covering different instruments.
Second workshop (planned): NIRCam/MIRI imaging, MIRI/MRS (star formation), NIRSpec
Scheduled time: around winter of FY2026
Further details will be announced separately once they are finalized.
★Venue: NAOJ Mitaka Campus
★Capacity: Approximately 20 to 30 participants (If the number of applications exceeds capacity, students will be given priority, but participants will be selected based on their statement of purpose.)
★Lecturers: Chikako Yasui (NAOJ), Taichi Uyama (ABC / NAOJ), Matthias Samland (Max Planck Institute for Astronomy), Kotomi Taniguchi (NAOJ), Natsuko Izumi (Nagoya University), and others
★Intended participants
・Students, researchers, and others who analyze data obtained with JWST.
・Those who plan to incorporate JWST data analysis into their own research, or have already done so, and who would like to learn the basics of data analysis.
★Contents
Since the start of JWST operations, a wide range of archival data has become publicly available. However, while resources such as JWebinars provide some introduction to data analysis methods, there are still relatively few opportunities within the Japanese community to share practical analysis techniques in a systematic manner. Through this workshop, we aim to help participants acquire the fundamental skills needed for JWST data analysis and to promote an environment in which JWST data can be utilized more easily and more actively.
In addition, this workshop aims to introduce reproducible data analysis workflows based on international standards, as practiced at leading overseas institutions, using real JWST datasets.
★Required knowledge and environment
・A Python environment is required for the workshop. Please also bring your own computer.
・You should be able to use a text editor (such as emacs, vi, or gedit).
・You should have basic Linux/UNIX knowledge (i.e., be able to use commands such as ls, cd, cp, rm, mkdir, and scp).
・Experience with programming in Python is required. In particular, experience with environment setup using Anaconda and with the interactive platform Jupyter Notebook is desirable.
・If any of the participants are not native Japanese speakers, the workshop may be conducted in English. We will announce this after the participants have been finalized.
13:00-16:30 Hands-on session for environment setup
This session is intended only for those who were unable to successfully install or download the pipelines and libraries required for data analysis. Participation is not mandatory for everyone.
This session is for troubleshooting only; introductions to the actual data analysis will begin on June 3 and later.
9:30-10:30 Registration
10:30-10:35 Opening remarks
10:35-11:05 Overview of JWST
11:05-11:10 Short break
11:20-11:50 How to download archival data
11:50-13:20 Lunch break
13:20-15:00 MIRI/MRS science and data analysis tutorial
15:00-15:15 Break
15:15-16:55 Coronagraph science and data analysis tutorial
17:00- A reception will be held after the end of the day's program.
10:00-12:00 Data analysis hands-on session
Participants will be divided into groups according to the instrument they wish to analyze (in principle, the hands-on session is intended to focus on only one instrument throughout both the morning and afternoon).
If you would like to participate in the hands-on sessions for both instruments, please consult us through the application form.
12:00-13:30 Lunch break
13:30-14:30 Data analysis hands-on session
14:30-14:45 Break
14:45-16:00 Presentation of practical session results
■How to apply
Applications for participation closed on May 7, 2026.
■Notes
・If the number of applications exceeds capacity, participants will be selected based on their motivation for using JWST data. Walk-in participation is not allowed, so anyone wishing to attend must submit an application in advance.
・Once the application form has been successfully submitted, a confirmation email will be sent automatically to the registered email address immediately afterward. If you do not receive this email, the form may not have been submitted properly, so please contact the workshop organizers below.
・We will contact applicants again in early May regarding whether they can participate in the workshop. Please note in advance that, if there are many applicants or if an applicant does not fall within the intended target group, participation may be declined.
・Travel support is not available for the first workshop. However, if you would like to stay at Cosmos Kaikan, please indicate this in the comments section of the application form. The organizers will check availability and respond accordingly.
