East Asian ALMA Science Workshop 2025 &
East Asian ALMA Data Analysis Workshop 2025
22-26 September, 2025

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

  1. Multi-bands (mentored by Dr. Kotomi Taniguchi, NAOJ)
    This topic will aim to obtain physical quantities (temperature, column density, dust grain size, etc.) from continuum and/or line data in multiple ALMA bands after beam matching.
    Members: Yang Erh Ching, Kibeop Lee, Lihwai Lin, Kushagra Srivastav, Hung Yu
  2. Polarization (mentored by Dr. Hiroshi Nagai, 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
  3. Self-calibration (mentored by Dr. Yu-Nung Su, ASIAA)
    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
  4. Sparse modeling (mentored by Dr. Masayuki Yamaguchi, Kyushu University) 　　
    This topic will aim to learn the idea of sparse modeling, apply the method to observed image(s) tuning parameters, and compare the output images with cleaned images.
    Members: Suzuka Arai, Hiroma Okubo, Yi Ren, Pialy Saha
  5. Total power combining + mosaic (mentored by Dr. Pei-Ying Hsieh, NAOJ) 　
    This topic will aim to learn the method for combining interferometric data and total-power (single dish) data together with the method for making images from mosaic ALMA observations.
    6. Members: Manojit Chakraborty, Yo-Ling Chuang, Jihye Hwang, Satyajeet Moharana, Yurika Nakamura
  6. Visibility fitting (mentored by Dr. Zhengyi Chen, NAOJ) 　
    This topic will aim to learn the process of fitting models directly to the visibility data obtained from interferometers. This method is used to determine source positions, flux densities, and structural parameters of astronomical objects.
    Members: Minori Esaki, Donghyeok Koh, Keisuke Nakashima, Wei-Ling Tseng, Ishizuka Yushi
  7. Basic course (mentored by Dr. Seokho Lee, KASI)
    This topic will target beginners, unlike the other topics. This topic will aim to learn basic ideas of imaging process (and calibration process if possible) of ALMA and make continuum and/or line images.
    Members: Ming-Tang Chen, Wei-Li Ling, Anzu Okazaki, Vinod Chandra Pathak, Majidul Rahaman, Shuntaro Sato


    –Please note that some of the topics, Polarization, needs some basic knowledge of interferometer data reduction, like clean etc.
