HI in the Universe (Ocasys
code STHIU-09)
This course consists of 4 weeks of lectures (from 08/02/2010 until 02/3/2010
(inclusive)). The final exam will consist of a paper.
Every week there are 2 lectures: on Mondays from 13.45-15:30 (J 5419.02161) and Tuesdays from 11.15-13:00 (J 5419.0161).
Lecture
outline:
Week 1: basic
physics, determination of HI properties of
galaxies, overview of HI
properties of galaxies
in
relation to other global galaxy properties
Week 2: HI as a tracer of galaxy dynamics, galaxy
evolution,
galaxy structure, star
formation
Week 3: HI surveys: HI properties, HI Mass Function,
HI
properties
as a function of environment
Week 4: relevance
for galaxy formation and evolution, the
cosmic
picture, future observational capabilities
Topics in week 2-4 will be
discussed on the basis of papers to be presented by the participants in the
course
The final grade will be based on the paper and the
presentation in class

Term Papers (hand in before
24 April 2010):
Write
a term paper on the basis of literature research on any of the following topics
or one of your own choosing. Structure it as a paper for the astronomical
literature with an introduction giving an overview of the status of the topic
and the relevant question(s) to be addressed, a section providing all the
information you found that is relevant to answering the question, a section
discussing the results and a section with conclusions.
Suggested subjects for term papers:
1. Discuss the Baryonic Tully-Fisher relation
2. Discuss the evidence for and applicability of star formation thresholds
3. Are there and should there be any starless galaxies
4. How well do we know HI spin temperatures
5. Discuss the properties of the lowest HI mass galaxies
6. Discuss the evidence for and importance of the Galactic Fountain
7. Discuss the importance and origin of damped Ly alpha systems
8. Discuss the possible origin and importance of warps
9. HI and the environment: evidence and implications for galaxy evolution
10. How well do we know the global gas density in the Universe
11. Discuss the HI properties of Elliptical galaxies
12. Discuss gas removal mechanisms
13. Discuss the importance of HI for tracing gravitational interaction
