Growth of Structure
This important topic is covered only sketchily by Liddle and
Rowan-Robinson, and you will find some useful additional material in
Bothun's book, which can be accessed online here,
though the Level 5
site. You will need to assemble a set of notes covering the topics
listed below. You may find my Unit 3 Lecture, and also section 9.2 from
the
Year 2 Structure in the
Universe course, useful to get an overview of the subject. You can
then fill in this framework by consulting the references below.
The main areas to address are:
- CMB fluctuations - RR(5.5), B(3.1), L(A5.4). Don't worry
if you don't
follow equation 3.5 in Bothun - I don't get it either.
- Jeans mass and the effects of pressure - B(5.1-5.1.3) is
useful
but more detailed than you need. No need to work through it in detail.
See also B(5.1.7), RR(6.1).
- Growth of density perturbations - B(3.1, 5.1.4-5.1.6) -
again
this
is rather detailed, aim to follow the idea and get the main
results, rather than working through blow-by-blow. L(A5.2) and R(6.1)
give it a brief mention.
- Collapse and virialisation - Unit 3 lecture, B(4.1.1).
Strangely absent from Liddle and R-R.
- Hierarchical merging - B(5.2.1, 5.3.1-5.3.2), unit 3
lecture,
RR(6.1-6.2)
Where RR=Rowan-Robinson, L=Liddle (2nd Ed.), and B=Bothun.
