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.

Topics
- Multi-bands
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. - Polarization
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. - Self-calibration
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. - Sparse modeling
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. - Total power combining + mosaic
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. - Visibility fitting
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. - Basic course
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.
please note that some of the topics, Polarization, needs some basic knowledge of interferometer data reduction, like clean etc.
