Required Knowledge:
It will be assumed you will have followed the basic lecture course "Cosmology". It is
not a formal requisite.
A recapitulation, overview and summary of the necessary knowledge of basic Cosmology (including some General Relativity),
will be the subject of the first week's lecture.
Exam:
The exam will consist of three/four elements:
written exam -- January 27, 2015: 09:00-12:30
presentation special topic
2 computer tasks
Literature:
The course will be based upon the lecture notes, to be distributed during the course.
No specific book will be followed. Nonetheless, several books are recommended for the purpose
of the necessary backup information, overlapping substantially with parts of the lecture material:
Cosmology
Steven Weinberg
Oxford University Press, 2008
ISBN 978-0198526827
Cosmological Physics
John Peacock
Cambridge University Press, 1998
ISBN 0521422701 (paper)
The most up-to-date books focussing on structure and galaxy formation are:
Galaxy
Formation
Malcolm Longair
Astronomy & Astrophysics Library, 2nd ed., Springer
ISBN 9783540734772 (hb)
Galaxy Formation and
Evolution
H.J. Mo, F. van den Bosch, S.D.M. White
Cambridge Univ. Press
ISBN 978-0521857932 (hb)
In addition, THE book on basic cosmology that I will always warmly recommend (but which you are not required
to have) - one of the few textbooks really fun reading and a marvel of didactic writing -- is:
Introduction to Cosmology
Barbara Ryden
Addison Wesley, 2002
ISBN 0805389121 (hardcover)
Interesting Scientific Publications
During the course several papers relating to the lecture content will be handed out. Here you may download them.
Lecture Notes & Exam Material:
The course is based upon the lecture notes. Below you find a listing of the notes.
The notes you can download in 3 forms:
* ppt file, a colour pdf (handout, 2 slices/page) and a greyscale pdf (handout, 2 slices/page)
* pdf file texed notes
* xerox copy, distributed during the course
Below you find a listing of the notes, and I will notify you when they become available. Subsequently, they
will be available for downloading.
Please check the notes you have. When you are missing one or more items contact me.

Werkcollege I: FRW cosmologyPresentation Topics:
The presentation is part of the final exam. The intention is to investigate in some detail and to some depth one particular topic related to the formation of structure in the Universe. You are expected to acquaint yourself with a few of the essential literature references and to critically assess them (do not always take statements for granted, the field is moving quickly, knowledge may get outdated, viewpoints may change or be proven wrong).
A list of 19 topics from which you are invited to choose:
Presentation Topics pdf
The presentations will be on thursday January 15 (11:00-13:00) and friday January 16 (11:00-13:00).
We are looking forward to some illuminating and interesting presentations ! Recall this may be deep stuff and we need to learn far more ourselves about most issues too. So please educate us !

For searching the astronomical literature the two most important website to consult are those of
ADS: NASA Astrophysics Data SystemNotice that ADS allows you to expand your literature search via the references of the paper under consideration, as well as the links to the papers that refer to it. While using this possibility wisely you may quickly find most relevant studies. Also notice that the links of ADS to the journals in which the papers are published may need you to use your student number + password for the University library, or you have registered with the University Library, when working from outside the university (e.g. from home). Otherwise you will not be able to use the university subscription to these journals.
