The fate of a galaxy is governed by an intricate ballet of gas flows: the flow of cool gas into the system, the conversion of these baryons into stars, and the ejection of gas enriched with heavy elements. This material flow is known as the galaxy baryon cycle. Determining what rules and mutually relates these three aspects still remains a critical and very complex problem in cosmology.
​
Key scientific questions addressed by the conference
Phase 1. The flow of cool gas
-
What are the key observables to definitely probe the cold gas accretion?
-
Is the cold/hot accretion transition merely dependent on the halo mass scale or is there a more general environmental dependence?
-
Are galaxies self-regulated systems in which accretion and feedback mutually trigger/limit each other?
Phase2. The conversion of baryons into stars
-
How does the neutral and molecular mass content of galaxies vary with galaxy properties and how do the two cold gas phases relate to each other?
-
Are simulations able to reproduce the observed galaxy properties and cold gas content, and their evolution?
Phase 3. The ejection of gas
-
Is there consensus on the nature of the ejection mechanism driving galactic gas outflows?
-
Is the ejected material able to escape the halo potential well?
-
What is the inflow/outflow interplay?
