Uitgebreide vaknaam Gas Flows in Galaxies (Capita Selecta, 22/23)
Leerdoelen At the end of the course, the student is able to:
- describe processes of gas inflow into galaxies from a theoretical and/or an observational point of view;
- describe processes of gas outflow from galaxies from a theoretical and/or an observational point of view;
- discuss the importance of gas flows for galaxy evolution;
- criticise the reliability of both theory and observations of gas flows from and to galaxies.
Omschrijving Gas flows are fundamental ingredients of the formation and the evolution of galaxies. This course gives an overview of the processes that bring gas from the intergalactic medium into galaxies and viceversa (inflow and outflow).
The inflow of gas, also called gas accretion, is at the basis of the growth of galaxies. It is a natural expectation of current cosmological models but the details of the process are very complex and poorly understood. In this course we investigate both the theoretical expectations and the observational evidence of gas accretion.
The outflow of gas is produced by energetic processes in galaxies mainly stellar and AGN feedback. Both processes are necessary to build models that reproduce populations of galaxies similar to the observed ones. We will review the current theoretical models of feedback and compare them with observations and back-of-the-envelop calculations.

Toetsvorm Presentatie (P)
(Each student will study carefully at least 2 papers and give at least 2 presentations. Typically, presentations last 20 minutes + discussion. The student will not pass if they do not give the minimum number of presentations or if their level is insufficient. To pass one needs a mark of 6/10 or higher on all presentations. The final mark is obtained as the average of the individual marks.)

Opmerkingen It is mandatory that the students are present on the two (or more) days of their own presentations. The first four hours of lectures by the teacher are also extremely important. The participation in the discussion following the presentations of other students is highly recommended and can increase the final mark
