The turbulent life of cosmic giants: How chaotic are galaxy clusters?

Kosmisches Kino on 8 May

11 April 2025

In this Kosmisches Kino, Dr Frederick Groth from the University Observatory Munich, LMU takes us on a journey into the turbulent interiors of galaxy clusters. He will show us what they are, how they work, and what we can learn about their history and evolution from supercomputer simulations. This English-language event will take place on 8 May 2025 at 19:00 in the ESO Supernova. Tickets cost 6.50 Euro each and can be booked online.

Galaxy clusters are groups of galaxies that can contain thousands of objects. They are held together by their own gravity and are the most massive bound structures in the universe. When entire galaxy clusters collide and merge, chaos ensues! What drives it? Join us on a journey through the turbulent universe and discover the stormy side of these cosmic giants!

The total mass of a galaxy cluster can be several hundred trillion times the mass of the Sun. However, the dominant component of its visible matter is not the stars or galaxies but the hot, diffuse gas in between the galaxies. Powerful large-scale gas flows, shock waves, and chaotic turbulence propagate through this so-called intracluster medium - processes that take many billions of years. These incredibly slow dynamics shape the intracluster medium and are key to understanding galaxy clusters and their evolution. But how can they be observed?

High-resolution computer simulations make it possible to calculate the evolution of galaxy clusters in time and bring order to this cosmic chaos. They help to understand the effects of cluster collisions, galaxy motions, active supermassive black holes, and stellar winds on the intracluster gas.

The event takes place on 8 May 2025 at 19:00 in the planetarium of the ESO Supernova and will be held in English. Tickets can be booked online. Since this is a live presentation there will be no translation available. The ESO Supernova will remain open until the start of the event for visitors, who can explore the exhibition at any time or watch a planetarium show beforehand.

 

More information

What is Kosmisches Kino?

Kosmisches Kino (Cosmic Cinema) takes visitors into the breathtaking depths of space. Researchers from the ORIGINS Cluster of Excellence will accompany you on your journey through the cosmos with selected excerpts from planetarium films and an associated lecture.

Sit back and marvel. Want to know more? Just ask! Kosmisches Kino events take place under the dome of the planetarium. They offer all visitors, no prior knowledge required, an atmospheric insight into the world of research and provide you with new insights. At the end of the event, the researchers answer questions from the audience.

The lecture series Kosmisches Kino is a collaboration between ESO and the ORIGINS Cluster of Excellence and presents current research topics. The ORIGINS Excellence Cluster combines astrophysics, particle physics and biophysics to investigate the formation of the Universe and the origin of life. The lectures address exciting questions that current research is investigating: Is there a common thread connecting the Big Bang with the origin of life? How do you measure radiation from space and its effect on humans? Where and how do planets and stars form? What is Dark Matter? What are the building blocks of life on Earth and do they exist elsewhere in space? These and many other questions will be addressed over the course of the event series.

Admission to the approximately one-hour-long evening event with planetarium visualisations, a live lecture and open discussion costs 6.50 Euros per person. Events are aimed at people aged 12 years and over.
