We are pleased to announce the 21cm & Cosmological Lines 2026 – Online Workshop (CLiW 2026), a three-day online event organized by the National Institute for Space Research (INPE), Brazil, to be held on October 21–23, 2026.
Registration and abstract submission are now open. Further information, including the scientific program, registration, abstract submission, and important deadlines, is available on the workshop website:
https://www.gov.br/inpe/en/events/21cm-cosmological-lines-2026
The workshop will bring together researchers working on the 21 cm signal and other cosmological emission lines, spanning topics from late-time cosmology to the Epoch of Reionization. The scientific program covers a broad range of observational approaches, including intensity mapping, interferometric observations, and global signal experiments, fostering discussions between theorists, observers, and instrumentalists.
The program features seven invited talks by leading researchers, contributed presentations, and a hands-on session based on publicly available MeerKLASS data, providing participants with practical experience in the analysis of cosmological line observations.
Important dates
• Abstract submission deadline: September 7, 2026.
• Registration deadline: October 15, 2026.
• Workshop: October 21–23, 2026.
Participation is free of charge.
