We are pleased to announce the East Asian (EA) ALMA Science Workshop 2025. The EA ALMA community of Taiwan, Korea, and Japan has gotten together every year to share new results and to promote collaborations among the researchers in the EA region. The workshop will be hosted at the Inamori Hall, Korimoto Campus of the Kagoshima University on September 22-24, 2025, which is near the Kagoshima Chuo Station in Kagoshima City. All researchers interested in ALMA are welcome to join. Following the successful EA ALMA Data Analysis Workshop held last year in Korea, we will also have the second EA ALMA Data Analysis Workshop on September 25-26, to facilitate collaboration and skill development among young astronomers. Through group work guided by experienced supervisors, we promote close interactions among the EA members.
With the Wideband Sensitivity Upgrade project making progress, we will have a discussion on synergies between ALMA and other facilities. Researchers working on synergetic studies with new facilities (e.g., JWST, …) and leading facilities that will be in operation in the near future (e.g., SKA, Vera C. Rubin Observatory) in the EA community are invited to discuss their works. We also hope to see many scientific results based on ALMA from the EA community. This will provide an opportunity to initiate collaborations aiming at EA-led ALMA Large Projects, while looking for avenues to further promote the presence of EA to the world.

Workshop Topics and Groups
- Multi-bands
(Mentor; Dr. Kotomi Taniguchi, NAOJ, Tutor; Dr. Jinshi Sai, Kagoshima Univ. )

Members: Yang Erh Ching, Shu Ishibashi, Kibeop Lee, Lihwai Lin, Kushagra Srivastav, Hung Yu - Polarization
(Mentor; Dr. Hiroshi Nagai, NAOJ, Tutor; Dr. Natsuko Izumi, NAOJ)
This topic will aim to derive spatial distributions of the polarization-intensity, -fraction, and -angle from observed Stokes I, Q, U (and V) images and visualize those quantities.
Members:Shivani Gupta, Takeshi Hoshino, Jyun-Heng Lin, Jongho Park, Saurav Sen, Yu-Syuan Tu - Self-calibration
(Mentor; Dr. Yu-Nung Su, ASIAA, Tutor; Ms. Miyu Kido, Kagoshima Univ.)
This topic will aim to apply the phase only and phase + amplitude self-calibration and investigate effects of various parameters, such as the solution time interval and clean threshold.
Members: Chikato Asaba, Kazuto Haraguchi, Soochan Kim, Hinako Okimura, Hsien-Ju Tsai - Sparse modeling
(Mentor; Dr. Masayuki Yamaguchi, Kyushu Univ., Tutor; Mr. Ayumu Shoshi, Kyushu Univ.)

Members: Suzuka Arai, Hiroma Okubo, Pialy Saha, Yuma Sugahara - Total power combining + mosaic
(Mentor; Dr. Pei-Ying Hsieh, NAOJ, Tutor; Dr. Sheng-Jun Lin, ASIAA)

- Visibility fitting
(Mentor; Dr. Zhengyi Chen, NAOJ, Tutor; Dr. Hsi-Wei Yen, ASIAA)

Members: Minori Esaki, Donghyeok Koh, Keisuke Nakashima, Wei-Ling Tseng - Basic course
(Mentor; Dr. Seokho Lee, KASI, Tutor; Dr. Aran Lyo, KASI)

Announcements from LOC
1. Transportation
The easiest way to get to the Korimoto Campus of Kagoshima University is to take Kagoshima city tram. The nearest station is Toso (唐湊) or Kogakubu-mae (工学部前). If your hotel is close to the Kagoshima Chuo station (鹿児島中央駅), you can also walk to the university for ~30 minutes. The Inamori Kaikan, the workshop place, is close to the tram stations. https://www.kagoshima-u.ac.jp/en/about/access.html
2. Registration
We will open the registration desk from 8:00 am on Sep. 22. The registration space is not so large, so please avoid the last-minutes registration. We will provide each participant with an eduroam internet account there. Each participant is supposed to pay 1000 yen for coffee, tea / snacks. If you will also attend the banquet, you also need to pay 7500 yen, thus 8500 yen in total. Please do your best to provide the exact amount of the Japanese cash, no change allowed. We will not accept any credit card or foreign currency.
3. Conference Hall in the Inamori Kaikan
The total number of the participants is 133, while the conference hall has 270 seats. Thus it is a little bit crowed, and please try to accommodate all the participants equally. We will distribute power cables for your laptop in the hall as much as we could. But it is impossible that everyone accesses the cable at the same time. Furthermore, because of the limitation of the power supply, the maximum number of the laptops to be connected simultaneously to the power is ~50. Please try to share the limited power supply equally. No food / drink is allowed in the hall, but presenters could bring a plastic bottle during their presentations.
4. Poster Hall
Poster place is outside the conference hall, facing to the tram street. As already announced, please put your poster with the relevant number tag. The number of the available poster boards is 30, and in total 60 posters can be put on the front and backsides. Several posters need to put on the wall. Coffee, tea, and snacks will be provided in that place. The poster hall is probably not big enough to accommodate 133 people at the same time. So again your corporation is helpful.
5. Meeting Rooms
Inamori Kaikan has middle-size (1st floor) and small-size (3rd floor) meeting rooms. You can freely use the rooms for your discussion / chat. In the lunch time of Sep. 24, the middle-sized room will be used for EASAC.
6. Lunch, Toilet
Toilet is in the basement of the Inamori Kaikan. You can also use the toilets in the separate buildings next to the Inamori Kaikan. For lunch, the easiest solution is to use the University cafeteria. There are two cafeterias open in the campus. However, Sep. 23 is the Japanese National Holiday (秋分の日), so the university is basically closed. The cafeterias will be closed, and you cannot enter any of the buildings except for the Inamori Kaikan. On Sep. 23, please try restaurants outside the campus. https://maps.app.goo.gl/8KXv1BLymGJJxTnB6
7. Banquet
There are 70 registrations plus two accompanying persons. No additional request, no cancellation, is allowed. Special requests are no pork or beef, vegetarian, and no seafood. Please note that those special requests are best-effort basis. The banquet place, Inamori memorial Hall (稲盛記念館), is on the 2nd floor of one of the university cafeterias. We will provide an Italian-style course menu. You can drink as much as you want, and thus you should drink as much as you could!
8. Others
The LOC members will wear a name tag with a red strap. If you have any question, please do not hesitate to ask the LOC members.
Sincerely,
Shigehisa Takakuwa, on behalf of LOC
