Write an essay describing the current standard cosmological model including aspects of theory and evidence for the model, focusing on the content of the universe (cold dark matter, baryons, etc.) and how galaxies have grown from seed fluctuations in the early universe.
1. Overview.
Give an overview of the current standard model for the context of the essay. Include one
figure for this section.
2. Dark Matter.
Describe two lines of evidence for dark matter. These should be distinct and complementary.
A line of evidence can consist of more than one observational phenomenon that together provide the evidence. Include two figures for this section.
3. Baryons.
Describe one indirect constraint on the baryon density (BBN or CMB), and key direct measurements of various baryonic components. Include two figures for this section.
4. Dark Energy.
Describe two lines of evidence for dark energy. Comment on possible modifications to the
standard model. Include two figures for this section.
5. Growth of structure.
Describe how initial fluctuations from inflation have grown to form galaxies. Consider the
growth rate on various scales, and the different behaviour of dark matter and baryons.
Include two figures for this section.
6. Conclusions.
Providing some concluding remarks and comment on future tests of the standard model.
