ORIGINS RU-D Science Day

Tuesday Sep 29, 2026, 8:50 AM → 10:30 PM Europe/Berlin

Main lecture hall (University Observatory Munich (USM))

Daniel Gruen (LMU Munich), Eric Emsellem (ESO), Stefan Heigl (LMU)

The ORIGINS RU-D Science Day is a one-day in-person workshop bringing together scientists from across the Munich area who work on the implications of cosmic evolution for habitability across various scales. The event aims to create an opportunity for researchers at all career stages to exchange ideas, learn about each other's work and encourage collaborations that extend beyond the event itself.

The event will focus on the central questions of research unit D: 

• How do physical processes govern the cascade of scales that drives the formation of galaxies, stars, and planets?
• How is cosmic matter processed and transformed across scales in diverse astrophysical environments?
• How do feedback processes and their chemo-energetic signatures shape, regulate, and enrich turbulent matter across all scales?
• How can observations be used to constrain the underlying physical processes operating on different scales?
• How can we build a synthetic Universe that enables robust comparisons between theoretical predictions and observations?

Whether you work directly on these topics or in related areas, we warmly invite you to join us for a day of scientific exchange. If you would like to present your work, we encourage you to submit an abstract until the 31st of August. There will be plenary talks and plenty of opportunities for focused break-out and discussion sessions. Therefore, we especially welcome work in progress that would benefit from discussion. Bring your questions as much as your answers.
