The origin and evolution of the primordial perturbation is the key to understanding structure formation in the earliest stages of the Universe. It carries clues to the types of physical phenomena active in that extreme high-density environment. Throu
A new model of thermal inflation is introduced, in which the mass of the thermal waterfall field is dependent on a light spectator scalar field. Using the $\delta N$ formalism, the "end of inflation" scenario is investigated in order to ascertain whe

This book gives an accessible account of the history of the Universe; not only what happened, but why it happened. An author of textbooks on the early Universe and inflation, David Lyth now explains both cosmology and the underlying physics to the ge

Before we get to physics and cosmology, there are some things I need to deal with. I’ll begin with the most important thing. s an analogy that might be helpful. Suppose you’ve completed a crossword, and somebody suggests that your solution may be

Physics explains how a rather ordinary sequence of events led to the present Universe. Wouldn’t you agree, now that you’ve read the book? If you would, you are forgetting about ourselves. We are part of the Universe but we somehow don’t fit int

It is natural to ask what happened, between the end of inflation and the beginning of the known history. To answer that question, we have to make assumptions which may or may not be correct. Most importantly, we have to make an assumption about the e

The previous chapter makes no reference to time. It simply asserts that the Universe is in thermal equilibrium during the first stage of the history, and that the temperature is then proportional to 1∕a. To understand the rest of the history, as de

In this chapter we will see how the second era of inflation can generate the energy density perturbation, that exists at the beginning of known history. The job might be done by a perturbation in the inflaton field, or else through a perturbation in
