Symposium S12  3-4 July 2024

Zooming In, Zooming Out: Exploring Galaxy Formation through Simulations

Aims and scope

Galaxy formation is a complex, multi-scale process that involves the interplay of various physical mechanisms, including gravity, gas dynamics, radiation, star formation, feedback from stars and active galactic nuclei (AGN), and the influence of dark matter. Galaxy formation occurs on a wide range of spatial scales, from the formation of individual stars within galaxies to the clustering of galaxies in cosmic filaments and clusters. Hence, simulations must cover an enormous dynamic range, from sub-parsecs to Megaparsecs, to capture all relevant physical processes.

With this symposium we aim to discuss the latest developments in cosmological simulations, focusing on challenges in the implementation of feedback processes, interstellar medium (ISM) physics, and radiative transfer. We aim at discussing the latest developments regarding the modelling of line emission from different gas phases and the state-of-the-art on dust emission and production mechanisms. Moreover, we will review recent updates on codes and models and the efforts in self-consistently considering key physical processes, such as radiative transfer and metal enrichment, on different scales.

Some of the questions we aim to tackle are the following: How do feedback processes from supernovae, stellar winds, and AGN influence galaxy evolution? How can simulations shed light on the impact of these processes on galaxy formation at early epochs? How do the synergy between data and numerical simulations can enhance our understanding of galaxy evolution? We will address the latest challenges in reproducing and interpreting data from ALMA and JWST observations and how observational data can help refining models and simulations.


The symposium consists of 6 blocks of 1.5 hour and includes invited talks, contributed talks, and flash talks. The following represent an overview of the expected talks and discussions in this Symposium:

  • Zoom in and zoom out: simulations across different scales
  • Feedback mechanisms and the ISM-CGM connection
  • ISM physics and radiative transfer
  • Dust and metals in simulations
  • Simulating AGN and black hole growth
  • Challenges in interpreting and reproducing ALMA/JWST data
