Why we meet, and what we will discuss.
Submillimeter astronomy, spanning the terahertz frequency regime, offers a critical observing window onto the mysteries of the Universe. Leading facilities such as ALMA, NOEMA and the EHT, together with upcoming next-generation facilities, are actively advancing our understanding of the dark and cold Universe — of black holes, galaxies, star formation and exoplanetary systems. Taking this chance, we initiate a focused, discussion-driven meeting in Hong Kong in 2026: the International Terahertz / Submillimeter Observing Universe Symposium (iTHUS). Three main themes will frame our discussions:
Terahertz / Submillimeter Astronomy Development
Next-generation facilities and technological advances poised to open new discovery space — from large single-dish telescopes to interferometric arrays — and the scientific breakthroughs they aim to unlock.
Black Holes · Star Formation · Galaxy Evolution
State-of-the-art science enabled by infrared, terahertz, and (sub)millimeter observations — from black hole imaging at the galactic centers to the cold gas reservoirs of the early Universe. Drawing on results from EHT, VLTI, ALMA, NOEMA and other facilities.
Forging Collaborations and Charting Future Routes
Opportunities for strategic collaboration across institutions, facilities, and continents — building a coordinated community around the next generation of terahertz and submillimeter science, aligning ambitions, sharing expertise, and defining a collective roadmap.
Keynotes, talks, and everyone joining us — badges show each person's role.
Speaker list as of November 2026. Final confirmations and talk titles will follow.
