Building Galaxies from Scratch: Advances and Challenges in Simulating Galaxy Evolution

19.-23. February 2024 in Vienna

Simulating galaxy formation is a challenging problem in theoretical astrophysics because of the wide range of scales and the large variety of physical processes involved. Feedback energy injected on scales of parsecs directly influences gas flows on scales as large as Megaparsec and important physical processes include not only gravity and (magneto)hydrodynamics, but also radiative cooling, star formation, radiation transport, as well as the physics of cosmic rays.
Despite these challenges, cosmological galaxy simulations have made drastic progress in the last decades, from being unable to produce disk galaxies at all to successfully reproducing the full population of galaxies in large cosmological box simulations (at least at low redshift). This success has been achieved with a broad number of different effective physics models and numerical schemes for galaxy physics, though even the numerical schemes for hydrodynamics and gravity are quite different.
In this meeting we present and examine the current state of the art of galaxy simulations in a cosmological context. We discuss the possible and best routes to the next generation of cosmological simulations that will further our insights into galaxy formation, one of the most complex problems in the Universe.

We are happy to provide you an invitation letter for a visa application! Note that this is only possible for registered participants (information on the registration can be found here). After registration, please send an email to both congress@univie.ac.at and bugs2024.astro@univie.ac.at (cc).  

 Poster presentations

If your abstract has been selected for a poster presentation, please bring a physical poster (max size: A0 portrait). The poster walls will be located in the same area as the welcome reception and the coffee breaks. For additional exposure, each poster presenter is given the opportunity to advertise their poster in a 1 minute flash talk during the main conference program.
