Announcements:


The first lecture will be on tuesday morning February 10, 13.7 minutes after 9 !!!!

The tutorial lectures of friday Feb. 27 will involve student presentations on Early Cosmology.

Because of a clash with the lecture series "Statistical Methods", it has been decided to shift the thursday lecture to friday morning 9:15-11:00. The tutorial lectures (werkcollege) will shift to friday morning 11:15-13:00. This will take effect as of the first week, the Feb. 12 lecture shifts to Feb. 13.




Required Knowledge:

There are no real requirements (except the usual basic knowledge of first and second year mathematics, physics and astrophysics. Although some familiarity with General Relativity will facilitate insight into the Universe, the lectures in the first week will provide the necessary background.



Lectures:

The lecture schedule will be:

      Tuesday 09:15-11:00    hoorcollege     ZG 161

      Friday 09:15-11:00      hoorcollege     ZG 161

       Friday 11:15-13:00    werkcollege    ZG 257


Exam:

The exam will consist of three/four elements:

      written exam -- tuesday April 21, 14:00-17:15, ZG161

      presentation (topic historical cosmology)

      2 computer tasks



General Information:

Practical information on the course -- literature, provisional schedule, topics presentation Early Cosmology -- you may find in:

     General Lecture Information




Literature:

The course will be based upon

     Lecture notes,
        to be distributed during the course
     Introduction to Cosmology
        Barbara Ryden
        Addison Wesley, 2002

        ISBN 0805389121 (hardcover)

This book entails a really fabulous introduction to the basic concepts of cosmology, nearly entirely up to date. It is one of the few textbooks really fun reading, a marvel of didactic writing. In particular for the later stages of the lecture series -- Cosmic Microwave Background, Cosmic Nucleosynthesis, Inflation -- I will assume you have the book.

In addition, there are three general cosmology books that from time to time you may wish to consult (but which are not obligatory fare for this course !!!). They are somewhat more demanding than the Ryden book, yet contain a lot of useful information,

     Cosmological Physics
        John Peacock
        Cambridge University Press, 1998

        ISBN 0521422701 (paper)

      Cosmology, The Origin and Evolution of Cosmic Structure
        P. Coles, F. Lucchin
        Wiley, 2n edition, 2002

        ISBN 0471489093

     Principles of Physical Cosmology
        P.J.E. Peebles
        Princeton Univ. Press

        ISBN 0691074283

Tentamen/Written Exam

The written exam is on:

      Tuesday April 21, 14:00-17:15; room ZG161




Presentation: Early Cosmology

Attached you find the files with topics for your presentation on "Early Cosmology".

Choose the topic of your choice, subsequently inform me about your choice. Alternatively you may choose a topic not mentioned in the list. In that case consult lecturer. After approval you can set to work on the subject.

      Early Cosmology

You are expected to prepare a 10-15 minute presentation (with ppt or pdf notes) !






Werkcollege (tutorials)

Attached you find the files with the werkcollege assignments.

     Werkcollege Feb 13, 20:      General Relativity, task 1-4

     Werkcollege Mar 6:             Newtonian Cosmology, Hubble expansion, Observational Cosmology, Anisotropic expansion, task 1-4

     Werkcollege Mar 13, 20:      Solutions to the FRW Universe, 1-2

     Werkcollege Mar 27:            Mattig Relations, Horizon at recombination, 1-2

     Werkcollege Apr 3:              Early Universe, 1-2

Important: the assignments that were not completed during the werkcollege/tutorial class, you are expected to solve yourself at home. Completed tasks should be turned in to your lecturer. Completed and approved tasks are required for completion of the course.

Thus: please turn them in to your tutor (ie. me) !

For questions and advice on the tasks you are of course welcome to contact your "werkcollegedocent", which is me ! Room 186 !





For searching the astronomical literature the two most important website to consult are those of

     ADS:       NASA Astrophysics Data System
     astro-ph:   astrophysics e-print server

Notice 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.
