Scope

Large millimeter/submillimeter interferometers such as ALMA have made numerous transformative discoveries in the Universe, from the phenomena surrounding stars and planets in the Milky Way galaxy to the characterization of dust and atomic lines in galaxies that are well within the Epoch of Reionization. VLBI networks such as VERA, JVN, and EAVN have revealed surprising structures and activities of AGN jets, part of which contributed to the success of the EHT observation of a black-hole shadow, as well as the dynamic and energetic nature of stars and compact objects. Such discoveries will presumably continue throughout this decade and well into the 2030s. In parallel, upcoming centimeter to millimeter interferometers would open up a new window on the Universe through sensitive imaging of line and continuum emission at unprecedented sensitivity and angular resolution. At the lower frequency bands, the Square Kilometre Array (SKA) would survey the nearby and distant universe with its exquisite sensitivity to the faintest emission, discovering thousands of new sources across the sky. At the higher frequency bands, the next generation Very Large Array (ngVLA) would study the detailed emission structure of astronomical sources with its superb angular resolution that would reach milli-arcseconds or even better. Both facilities are expected to provide scientific breakthroughs in many fields of astronomy and astrophysics, and a well-planned synergy between the new and existing facilities will inevitably amplify the scientific value of all ground-based radio interferometric facilities operating in the 2030s and beyond. Japan is currently investigating the possibility of entering the two spectacular projects, SKA and ngVLA, and gaining access to observing time when both arrays become available in the future. This workshop brings together scientists and students who are interested in the new science enabled by these instruments. Specifically, the goals of this workshop are to (1) identify scientific synergies between future large interferometers, SKA and ngVLA, and their synergies with current facilities such as ALMA and VLBI collaborations, (2) discuss the future science landscape with large interferometers (ALMA, VLBI, SKA, ngVLA) for the Japanese community in the 2030s and beyond.
We encourage early career stage scientists to participate and discuss the exciting new science cases enabled by linking the new and existing large interferometers in the 2030s.
