RU-D "From Cosmic Large-Scale Structure to Galaxies, Stars and Planets" Science Day at the Excellence Cluster ORIGINS

Wednesday Apr 19, 2023, 9:00 AM → 5:00 PM Europe/Berlin

auditorium Eridanus (ESO)

Alexandre Barreira (LMU & ORIGINS Excellence Cluster), Eleonora Bianchi (Excellence Cluster ORIGINS), Eric Emsellem (ESO), Simona Vegetti (MPA)

We take the opportunity of a RU-D Day meeting to both promote science conducted within the Research Units Galaxy, Stars and Planets, as well as brainstorm for ORIGINS 2 proposals.

The two morning sessions will be dedicated to hearing from and discussing science from 12 contributors associated with RU-D.

During the two afternoon sessions, we will provide details on the framework of the follow-up of ORIGINS (ORIGINS 2) and the timeline that will serve the set up of objectives and projects. New ideas for connectors and projects will be exposed, followed by a brain-storming session.

You are strongly encourage to join us in the Eridanus Auditorium at ESO for a live meeting. For those who unfortunately cannot join, here is a link:

Session 2: RU-D Science Talks

7 Tales from a multiphase Universe

Many astrophysical systems such as the interstellar, circumgalactic or intracluster media -- but also galactic winds, accretion disks or stellar coronae -- are multiphase, that is, colder gas phases are embedded in a larger, volume-filling hot phase. Such structure is hard to model and thus leads to usually unconverged large scale (e.g., cosmological) simulations. In spite of being present in such a variety of settings and scales, I will show in my talk that we can use a common theory to model the coupling between the phases -- inspired by the completely different field of turbulent combustion. This theory helps us understand incomplete observations (as we can often only observe one phase), fueling processes or convergence criteria for larger-scale simulations. Time provided, I will discuss how magnetic fields can suppress
mixing and cooling and thus potentially alter the previously described theory.

Speaker: Max Gronke (MPA)
